+
+Meson_UT_Enhancements
+=====================
+
+The meson build support for unit tests is now available and the more enhancements are done to the build system
+to classify unit tests under different categories. The build `test/test/meson.build` file has been
+modified for these enhancements. This document will further down describe the below list.
+
+*  Building and Running the unit tests.
+*  Grouping of testcases.
+*  Parallel and non parallel tests.
+*  Test suites.
+*  How to run different test suites.
+*  Support for skipped tests.
+
+
+Building and Running the unit tests
+-----------------------------------
+
+*  Create the meson build output folder using command.
+
+   ``$meson <build_dir>``
+
+*  Enter into build output folder, which was created by above command.
+
+   ``$cd build``
+
+*  Compile DPDK using `$ninja`.
+   The output file of the build will be available in meson build folder.
+   After successful ninja, binary `dpdk-test` is created in `build/test/test/`.
+
+*  Run the unit testcases.
+
+   ``$ninja test`` (or) ``$meson test``
+
+*  To rebuild the build directory, after any changes to meson.build.
+
+   ``$meson configure``
+
+*   To run specific test case via meson command.
+
+   ``$meson test <test case>`` (or) ``$ninja test <test case>``
+
+
+Grouping of testcases
+---------------------
+
+Testcases has been grouped into below four different groups based on conditions
+of time duration and performance of the individual testcase.
+
+*  fast_parallel_test_names
+*  fast_non_parallel_test_names
+*  perf_test_names
+*  driver_test_names
+*  dump_test_names
+
+Parallel and non parallel tests
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Unless specified the meson will run all unit tests as parallel by default.
+So the test cases are categorized into parallel and non parallel tests purely
+based test case functionality using `is_parallel` argument of `test()`
+in meson.build. Test cases marked with `is_parallel : true` will run in
+parallel and tests marked with `is_parallel : false` will run in non-parallel.
+While non-parallel test is running, any other test should not be run.
+Parallel and non parallel test cases are grouped under the
+`fast_parallel_test_names` and `fast_non_parallel_test_names`.
+
+Test suites
+~~~~~~~~~~~
+
+Test groups are considered as "suite” in `meson.build` and can be provided
+as argument to `test()` as  `suite ‘project_name:label’`
+
+    Ex: ``suite ‘DPDK:fast-tests’``
+
+Running different test suites
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Below are commands to run testcases using option `suite`
+
+*  Test cases from the groups `fast_parallel_test_names` and `fast_non_parallel_test_names`
+   are run under 10seconds and below is the meson command to run them.
+
+   ``$meson test --suite DPDK:fast-tests``
+
+*  Test cases from the group `perf_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$meson test --suite DPDK:perf-tests``
+
+*  Test cases from the group `driver_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$meson test --suite DPDK:driver-tests``
+
+*  Test cases from the group `dump_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$meson test --suite DPDK:dump-tests``
+
+
+Skipped testcases
+-----------------
+
+Some unit test cases have dependency on external libraries, driver modules or
+config flags, without which the test cases cannot be run, such test cases
+should return TEST_SKIPPED when mentioned dependencies are not enabled. To make
+test cases run user should enable relevant dependencies. Below are the few
+current scenarios when test cases are skipped:
+
+#. External library dependency paths are not set.
+#. Config flag for the dependent library is not enabled.
+#. Dependent driver modules are not installed on the system.
+
+Dependent library paths can be set using below
+
+*  Single path ``export LIBRARY_PATH=path``
+
+*  Multiple paths ``export LIBRARY_PATH=path1:path2:path3``
+
+Dependent library headers path can be exported as below.
+
+*  Single path ``$CFLAGS=-I/path meson build``
+
+*  Multiple paths ``$CFLAGS=-I/path1 -I/path2 meson build``
+
+Below examples shows how to export libraries and their header paths.
+
+To export single library at a time.
+
+        ``$export LIBRARY_PATH=/root/wireless_libs/zuc/``
+        ``$CFLAGS=-I/root/wireless_libs/zuc/include meson build``
+
+To export multiple libraries at a time.
+
+        ``$export LIBRARY_PATH=/root/wireless_libs/zuc/:/root/wireless_libs/`` \
+                                                    ``libsso_kasumi/build/``
+        ``$CFLAGS=-I/root/wireless_libs/zuc/include -I/root/wireless_libs/`` \
+                                        ``libsso_kasumi/include meson build``
+
+
+
+Commands to run meson UTs
+-------------------------
+
+*   To run all test cases
+       ``$meson test``
+*   To run specific test
+       ``$meson test testcase_name``
+        Ex:``$meson test acl_autotest``
+*   To run specific test suite
+       ``$meson test --suite DPDK:suite_name``
+        Ex:``$meson test --suite DPDK:fast-tests``

When incorrect core value or range provided,
as part of -l command line option, a crash occurs.

Added valid range checks to fix the crash.

You did not take my other comments into account and the ut updates are
missing.

Create bonded device test is failing due to improper initialisation in
bonded device configuration. which leads to crash while setting up queues.

The value of nb_rx_desc is checked if it is not in range of rx_desc_lim of
bonded device which fails.
This is due to "rx_desc_lim" is set to 0 as default value of bonded device
during bond_alloc().
Hence nb_rx_desc (1024) is > 0 and test fails.

Fix is to set the default values of rx_desc_lim of bonded device to
appropriate value.

The default values for the bond device aren't known until the first
slave is added.  Can you explain your setup?  What PMD are you
using for testing?

As far as I understand, 'rte_eth_rx_queue_setup()' is failing with bond eth
device since 'nb_rx_desc' should be less than 'dev_info.rx_desc_lim.nb_max' but
bonding sets 0 to 'nb_max'.

But not sure how to handle this from bonding point of view, this patch gives
most permissive values, but should bonding get these values from its slaves?

We ran link_bonding_autotest in test application and was failing the test_create_bonded_device as in below log.
Slaves are added during test suite setup and then bonded device is created as per ut.

eal_parse_corelist can error for both invalid core number but also for
incorrectly formatted input.
How about "invalid core list, please check core numbers are in [0, %u]
range" ?

Well, the maximum value is not really "999999999".
Please check against RTE_MAX_LCORE.

When incorrect core value or range provided,
as part of -l command line option, a crash occurs.

Added valid range checks to fix the crash.

Added ut check for negative core values.
Added unit test case for invalid core number range.

I did not see this before, but you fixed the "-l" eal option, not
"--lcores" option.
So those unit tests are wrong.

Passing "RTE_MAX_LCORE+1" is indeed wrong (be it with "-l" or "--lcores"
options), but I would still prefer to check the formatted value of
RTE_MAX_LCORE (no need for that +1, btw).
So please, in next version, test against "-l", RTE_STR(RTE_MAX_LCORE) and
"-l", "1-" RTE_STR(RTE_MAX_LCORE).


Thanks.

I relooked into this, these values should be filled from salve data like the way done for max_nb_rx_queues and max_nb_tx_queues
Existing code snippet:
if (slave_info.max_rx_queues < max_nb_rx_queues)
                          max_nb_rx_queues = slave_info.max_rx_queues;

 if (slave_info.max_tx_queues < max_nb_tx_queues)
                        max_nb_tx_queues = slave_info.max_tx_queues;

So, something like below you should add for rx/tx desc limit I guess.

if (slave_info.rx_desc_lim.nb_max < max_rx_desc_lim)
                                max_rx_desc_lim = slave_info.rx_desc_lim.nb_max;

if (slave_info.tx_desc_lim.nb_max < max_tx_desc_lim)
                                max_tx_desc_lim = slave_info.tx_desc_lim.nb_max;

dev_info->rx_desc_lim.nb_max = max_rx_desc_lim;
        dev_info->tx_desc_lim.nb_max = max_tx_desc_lim;

@Williams/Declan: Does this make sense?

Thanks,
Reshma

Separate issue, from my pov.
I would say the issue happens with a dpdk process that has no cpu available
wrt CONFIG_RTE_MAX_CORES.
eal_auto_detect_cores() then removes all cores from cfg->lcore_role[], then
eal_adjust_config() an incorrect master lcore is chosen at
cfg->master_lcore = rte_get_next_lcore(-1, 0, 0); ?

+Meson_UT
+========
+
+The meson build for unit tests under different categories is supported using 'test/test/meson.build'.
+
+This document describes the below list in detail.
+
+*  Building and Running the unit tests.
+*  Grouping of testcases.
+*  Parallel and non parallel tests.
+*  Test suites.
+*  How to run different test suites.
+*  Support for skipped tests.
+
+
+
+Building and Running the unit tests
+-----------------------------------
+
+*  Create the meson build output folder using command.
+
+   ``$meson <build_dir>``
+
+*  Enter into build output folder, which was created by above command.
+
+   ``$cd build``
+
+*  Compile DPDK using `$ninja`.
+   The output file of the build will be available in meson build folder.
+   After successful ninja command, binary `dpdk-test` is created in `build/test/test/`.
+
+*  Run the unit testcases.
+
+   ``$ninja test`` (or) ``$meson test``
+
+*  To rebuild the build directory, after any changes to meson.build.
+
+   ``$meson configure``
+
+*   To run specific test case via meson command.
+
+   ``$meson test <test case>`` (or) ``$ninja test <test case>``
+
+
+
+Grouping of testcases
+---------------------
+
+Testcases has been grouped into below four different groups based on conditions
+of time duration and performance of the individual testcase.
+
+*  fast_parallel_test_names
+*  fast_non_parallel_test_names
+*  perf_test_names
+*  driver_test_names
+*  dump_test_names
+
+Parallel and non parallel tests
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Unless specified the meson will run all unit tests as parallel by default.
+So the test cases are categorized into parallel and non parallel tests purely
+based on test case functionality using `is_parallel` argument of `test()`
+in meson.build. Test cases marked with `is_parallel : true` will run in
+parallel and tests marked with `is_parallel : false` will run in non-parallel.
+While non-parallel test is running, any other test should not be run.
+Parallel and non parallel test cases are grouped under the
+`fast_parallel_test_names` and `fast_non_parallel_test_names`.
+
+
+
+Test suites
+~~~~~~~~~~~
+
+Test groups are considered as "suite” in `meson.build` and can be provided
+as argument to `test()` as  `suite ‘project_name:label’`
+
+    Ex: ``suite ‘DPDK:fast-tests’``
+
+Running different test suites
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Below are commands to run testcases using option `suite`
+
+*  Test cases from the groups `fast_parallel_test_names` and `fast_non_parallel_test_names`
+   are run under 10seconds and below is the meson command to run them.
+
+   ``$meson test --suite DPDK:fast-tests``
+
+*  Test cases from the group `perf_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$meson test --suite DPDK:perf-tests``
+
+*  Test cases from the group `driver_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$meson test --suite DPDK:driver-tests``
+
+*  Test cases from the group `dump_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$meson test --suite DPDK:dump-tests``
+
+
+
+Skipped testcases
+-----------------
+
+Some unit test cases have dependency on external libraries, driver modules or
+config flags, without which the test cases cannot be run, such test cases
+should return TEST_SKIPPED when mentioned dependencies are not enabled. To make
+test cases run user should enable relevant dependencies. Below are the few
+current scenarios when test cases are skipped:
+
+#. External library dependency paths are not set.
+#. Config flag for the dependent library is not enabled.
+#. Dependent driver modules are not installed on the system.
+
+Dependent library paths can be set using below
+
+*  Single path ``export LIBRARY_PATH=path``
+
+*  Multiple paths ``export LIBRARY_PATH=path1:path2:path3``
+
+Dependent library headers path can be exported as below.
+
+*  Single path ``$CFLAGS=-I/path meson build``
+
+*  Multiple paths ``$CFLAGS=-I/path1 -I/path2 meson build``
+
+Below examples shows how to export libraries and their header paths.
+
+To export single library at a time.
+
+        ``$export LIBRARY_PATH=/root/wireless_libs/zuc/``
+        ``$CFLAGS=-I/root/wireless_libs/zuc/include meson build``
+
+To export multiple libraries at a time.
+
+        ``$export LIBRARY_PATH=/root/wireless_libs/zuc/:/root/wireless_libs/`` \
+                                                    ``libsso_kasumi/build/``
+        ``$CFLAGS=-I/root/wireless_libs/zuc/include -I/root/wireless_libs/`` \
+                                        ``libsso_kasumi/include meson build``
+
+
+
+Commands to run meson UTs
+-------------------------
+
+*   To run all test cases
+       ``$meson test``
+*   To run specific test
+       ``$meson test testcase_name``
+        Ex:``$meson test acl_autotest``
+*   To run specific test suite
+       ``$meson test --suite DPDK:suite_name``
+        Ex:``$meson test --suite DPDK:fast-tests``

This should not be necesary. If you make any changes to meson.build then
ninja will automatically detect that and call meson to reconfigure itself
automatically.

Also, I don't think the rebuilding of the software is within the scope of
the section of the document. I'd omit the whole bullet point.

"meson" rather than "the meson" sounds better. Comma needed after
"specified". I'd also look to shorten the next sentence and merge it with
the one above, which sounds incomplete.

"any other test should not be run" -> "no other tests should run".

Watch out for the use of smart-quotes in the text above. Regular single and
double quotes are recommended.

When passing a suite to the meson to run, you use "--suite", so please
include the "--" prefix to avoid confusion.

Break the sentence after "run".

Please be consistent with use of "export" or not. Also, consistently (or
not) using "$" for prompt would be good too.

+========
+
+The meson build for unit tests under different categories is supported using 'test/test/meson.build'.
+
+This document describes the below list in detail.
+
+*  Building and Running the unit tests.
+*  Grouping of testcases.
+*  Parallel and non parallel tests.
+*  Test suites.
+*  How to run different test suites.
+*  Support for skipped tests.
+
+
+
+Building and Running the unit tests
+-----------------------------------
+
+*  Create the meson build output folder using command.
+
+   ``$ meson <build_dir>``
+
+*  Enter into build output folder, which was created by above command.
+
+   ``$ cd build``
+
+*  Compile DPDK using `$ ninja`.
+   The output file of the build will be available in meson build folder.
+   After successful ninja command, binary `dpdk-test` is created in `build/test/test/`.
+
+*  Run the unit testcases.
+
+   ``$ ninja test`` (or) ``$ meson test``
+
+*   To run specific test case via meson command.
+
+   ``$ meson test <test case>`` (or) ``$ ninja test <test case>``
+
+
+
+Grouping of testcases
+---------------------
+
+Testcases has been grouped into below four different groups based on conditions
+of time duration and performance of the individual testcase.
+
+*  fast_parallel_test_names
+*  fast_non_parallel_test_names
+*  perf_test_names
+*  driver_test_names
+*  dump_test_names
+
+Parallel and non parallel tests
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, meson will run test cases in parallel. However `is_parallel` argument
+of `test()` in meson.build can be used to run tests in parallel or non-parallel
+mode based on its functionality. Test cases marked with `is_parallel : true` will
+run in parallel and tests marked with `is_parallel : false` will run in non-parallel.
+While non-parallel test is running, no other test should run.
+Parallel and non parallel test cases are grouped under the `fast_parallel_test_names`
+and `fast_non_parallel_test_names`.
+
+
+
+Test suites
+~~~~~~~~~~~
+
+Test groups are considered as `--suite` in `meson.build` and can be provided
+as argument to `test()` as  `--suite ‘project_name:label’`.
+
+    Ex: ``$ mesin test --suite ‘DPDK:fast-tests’``
+
+Running different test suites
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Below are commands to run testcases using option `suite`
+
+*  Test cases from the groups `fast_parallel_test_names` and `fast_non_parallel_test_names`
+   are run under 10seconds and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:fast-tests``
+
+*  Test cases from the group `perf_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:perf-tests``
+
+*  Test cases from the group `driver_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:driver-tests``
+
+*  Test cases from the group `dump_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:dump-tests``
+
+
+
+Skipped testcases
+-----------------
+
+Some unit test cases have dependency on external libraries, driver modules or
+config flags, without which the test cases cannot be run. such test cases
+should return TEST_SKIPPED when mentioned dependencies are not enabled. To make
+test cases run user should enable relevant dependencies. Below are the few
+current scenarios when test cases are skipped:
+
+#. External library dependency paths are not set.
+#. Config flag for the dependent library is not enabled.
+#. Dependent driver modules are not installed on the system.
+
+Dependent library paths can be set using below
+
+*  Single path ``$ export LIBRARY_PATH=path``
+
+*  Multiple paths ``$ export LIBRARY_PATH=path1:path2:path3``
+
+Dependent library headers path can be stated as part of meson build command as below.
+
+*  Single path ``$ CFLAGS=-I/path meson build``
+
+*  Multiple paths ``$ CFLAGS=-I/path1 -I/path2 meson build``
+
+Below examples shows how to export libraries and their header paths.
+
+To specify single library at a time.
+
+        ``$ export LIBRARY_PATH=/root/wireless_libs/zuc/``
+        ``$ CFLAGS=-I/root/wireless_libs/zuc/include meson build``
+
+To specify multiple libraries at a time.
+
+        ``$ export LIBRARY_PATH=/root/wireless_libs/zuc/:/root/wireless_libs/`` \
+                                                    ``libsso_kasumi/build/``
+        ``$ CFLAGS=-I/root/wireless_libs/zuc/include -I/root/wireless_libs/`` \
+                                        ``libsso_kasumi/include meson build``

+
+
+
+Grouping of testcases
+---------------------
+
+Testcases has been grouped into below four different groups based on conditions
+of time duration and performance of the individual testcase.
+
+*  fast_parallel_test_names
+*  fast_non_parallel_test_names
+*  perf_test_names
+*  driver_test_names
+*  dump_test_names
+
+Parallel and non parallel tests
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, meson will run test cases in parallel. However `is_parallel` argument
+of `test()` in meson.build can be used to run tests in parallel or non-parallel
+mode based on its functionality. Test cases marked with `is_parallel : true` will

+While non-parallel test is running, no other test should run.
+Parallel and non parallel test cases are grouped under the `fast_parallel_test_names`
+and `fast_non_parallel_test_names`.
+
+
+
+Test suites
+~~~~~~~~~~~
+
+Tests are grouped into test suites in meson.build and these suite names can be provided
+as argument to `meson test` as `--suite ‘project_name:label’`.
+
+    Ex: ``$ meson test --suite ‘DPDK:fast-tests’``
+
+Running different test suites
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Below are commands to run testcases using option `suite`
+
+*  Test cases from the groups `fast_parallel_test_names` and `fast_non_parallel_test_names`
+   are run under 10seconds and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:fast-tests``
+
+*  Test cases from the group `perf_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:perf-tests``
+
+*  Test cases from the group `driver_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:driver-tests``
+
+*  Test cases from the group `dump_test_names` are run under 600 seconds
+   and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:dump-tests``
+
+
+
+Skipped testcases
+-----------------
+
+Some unit test cases have dependency on external libraries, driver modules or
+config flags, without which the test cases cannot be run. Such test cases
+should return TEST_SKIPPED when mentioned dependencies are not enabled. To make
+test cases run user should enable relevant dependencies. Below are the few

+
+Dependent library paths can be set using below
+
+*  Single path ``$ export LIBRARY_PATH=path``

Create bonded device test is failing due to improper initialisation in
bonded device configuration. which leads to crash while setting up queues.

The value of nb_rx_desc is checked if it is not in range of rx_desc_lim of
bonded device which fails.
This is due to "rx_desc_lim" is set to 0 as default value of bonded device
during bond_alloc().
Hence nb_rx_desc (1024) is > 0 and test fails.

Fix is to set the default values of rx_desc_lim of bonded device to
appropriate value.

Some sections I think need rewording to be written more from an end-user
rather than developer point of view, since this text is focused on running unit
tests rather than on writing them. Some additional spelling/grammar
corrections below also.

NOTE: Since this is in the programmers guide, maybe the intention is to
have it more at the programmer level. In which case, you need more info on
writing tests, and what return values should be used etc. other than
"TEST_SKIPPED", and can skip some of the detail on running tests.

Should be just 2019, or 2018-2019, since this doc was not started in 2014.

This line is not wrong, just probably unnecessary. Consider omitting it, I
think, since this doc is about using the unit tests rather than about the
source code layout or individual files.

Are test suites not the same as the grouping of test cases?

Like the other commands above, this should be put on its own line.

Remove the word "below" as it's unnecessary.

Since you are listing the groups, I think you should just put the groups
without using the official variable names, which looks wrong and doesn't
add any info. Instead the list should be:

* fast tests which can be run in parallel
* fast tests which must run serially
* performance tests
* driver tests
* tests which produce lists of objects as output, and therefore that need manual checking

The above paragraph is too low level. It can probably be dropped or
abbreviated to a single sentence included in the previous section. Again,
this text seems targeted at users, not developers, so variable names in the
meson.build file are irrelevant.

Again, drop the variable names. Not relevant for users.

"are run under 10seconds" -> "should take less than 10 seconds"

Since these just output things, do they really need a 600 second timeout?
Do we even need to mention it?

Needs rewording for a more user-focused point of view, since TEST_SKIPPED
is an internal "magic number" in the code. Something like:
"Such test cases will be reported out as skipped if they cannot run. To
enable those test cases, the user should ensure the required dependencies
are met. Below are a few possible causes why tests may be skipped and how
they may be resolved:"

The high-level problem is more that the library is not found, not that the
path is unset. The solution is to set the path to the dependency if
necessary.

+
+This document describes the below list in detail.
+
+*  Building and Running the unit tests.
+*  Grouping of testcases.
+*  How to run different test suites.
+*  Support for skipped tests.
+
+
+
+Building and Running the unit tests
+-----------------------------------
+
+*  Create the meson build output folder using command.
+
+   ``$ meson <build_dir>``
+
+*  Enter into build output folder, which was created by above command.
+
+   ``$ cd build``
+
+*  Compile DPDK using command.
+
+  ``$ ninja``
+
+  The output file of the build will be available in meson build folder.
+  After successful ninja command, binary `dpdk-test` is created in `build/test/test/`.
+
+*  Run the unit testcases.
+
+   ``$ ninja test`` (or) ``$ meson test``
+
+*   To run specific test case via meson command.
+
+   ``$ meson test <test case>`` (or) ``$ ninja test <test case>``
+
+
+
+Grouping of testcases
+---------------------
+
+Testcases have been grouped into four different groups based on conditions
+of time duration and performance of the individual testcase.
+
+*  fast tests which can be run in parallel
+*  fast tests which must run serially
+*  performance tests
+*  driver tests
+*  tests which produce lists of objects as output, and therefore that need manual checking
+
+Testcases can be run in parallel or non-parallel mode using the `is_parallel` argument
+of `test()` in meson.build
+
+These tests can be run using the argument to `meson test` as
+`--suite ‘project_name:label’`.
+
+    Ex: ``$ meson test --suite ‘DPDK:fast-tests’``
+
+Running different test suites
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Commands to run testcases using option `--suite`
+
+*  Fast Tests should take less than 10 seconds and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:fast-tests``
+
+*  Performance Tests should take less than 600 seconds and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:perf-tests``
+
+*  Driver Tests should take less than 600 seconds and below is the meson command to run them.
+
+   ``$ meson test --suite DPDK:driver-tests``
+
+*  Below is the meson command to run Dump Tests
+
+   ``$ meson test --suite DPDK:dump-tests``
+
+
+
+Skipped testcases
+-----------------
+
+Some unit test cases have a dependency on external libraries, driver modules or
+config flags, without which the test cases cannot be run. Such test cases will be reported
+out as skipped if they cannot run. To enable those test cases,
+the user should ensure the required dependencies are met.
+Below are a few possible causes why tests may be skipped and how they may be resolved:
+
+#. External library is not found.
+#. Config flag for the dependent library is not enabled.
+#. Dependent driver modules are not installed on the system.
+
+To help find missing libraries, the user can specify addition search paths
+for those libraries as below:
+
+*  Single path ``$ export LIBRARY_PATH=path``
+
+*  Multiple paths ``$ export LIBRARY_PATH=path1:path2:path3``
+
+Some functionality may be disabled due to library headers being missed as part of the build.
+To specify an addition search path for headers at configuration time, use one of the commands below:
+
+*  Single path ``$ CFLAGS=-I/path meson build``
+
+*  Multiple paths ``$ CFLAGS=-I/path1 -I/path2 meson build``
+
+Below examples shows how to export libraries and their header paths.
+
+To specify single library at a time.

test_create_bonded_device is failing due to improper initialisation in
bonded device configuration. Which leads to crash while setting up queues.

The value of nb_rx_desc is checked if it is not in range of rx_desc_lim of
bonded device which fails.
This is due to "rx_desc_lim" is set to 0 as default value of bonded device
during bond_alloc().
Hence nb_rx_desc (1024) is > 0 and test fails.

Fix is to set the default values of rx_desc_lim of bonded device to
appropriate value.
Receive the values from slaves configuration like done for other existing
slave configuration

Fixes: 2efb58cbab6e ("bond: new link bonding library")

+
+Running DPDK Unit Tests with Meson
+==================================
+
+This section describes how to run testcases with the DPDK meson build system.
+
+
+Building and running the unit tests
+-----------------------------------
+
+* Create the meson build output folder using the following command::
+
+      $ meson <build_dir>
+
+* Enter into build output folder, which was created by above command::
+
+      $ cd build
+
+* Compile DPDK using command::
+
+      $ ninja
+
+The output file of the build will be available in meson build folder. After
+a successful ninja command, the binary ``dpdk-test`` is created in
+``build/test/test/``.
+
+* Run the unit testcases::
+
+      $ ninja test
+      # or
+      $ meson test
+
+* To run specific test case via meson::
+
+      $ meson test <test case>
+      # or
+      $ ninja test <test case>
+
+
+Grouping of testcases
+---------------------
+
+Testcases have been grouped into four different groups based on conditions
+of time duration and performance of the individual testcase.
+
+* Fast tests which can be run in parallel.
+* Fast tests which must run serially.
+* Performance tests.
+* Driver tests.
+* Tests which produce lists of objects as output, and therefore that need
+  manual checking.
+
+Testcases can be run in parallel or non-parallel mode using the ``is_parallel`` argument
+of ``test()`` in meson.build
+
+These tests can be run using the argument to ``meson test`` as
+``--suite project_name:label``.
+
+For example::
+
+    $ meson test --suite DPDK:fast-tests
+
+
+The project name is optional so the following is equivalent to the previous
+command::
+
+
+    $ meson test --suite fast-tests
+
+
+Running different test suites
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following commands are some examples of how to run testcases using option
+``--suite``:
+
+* Fast Tests should take less than 10 seconds. The meson command to run them
+  is::
+
+      $ meson test --suite DPDK:fast-tests
+
+* Performance Tests should take less than 600 seconds. The meson command to
+  run them is::
+
+      $ meson test --suite DPDK:perf-tests
+
+* Driver Tests should take less than 600 seconds. The meson command to run
+  them is::
+
+      $ meson test --suite DPDK:driver-tests
+
+* The meson command to run Dump Tests is::
+
+      $ meson test --suite DPDK:dump-tests
+
+
+Dealing with skipped testcases
+------------------------------
+
+Some unit test cases have a dependency on external libraries, driver modules
+or config flags, without which the test cases cannot be run. Such test cases
+will be reported as skipped if they cannot run. To enable those test cases,
+the user should ensure the required dependencies are met.  Below are a few
+possible causes why tests may be skipped and how they may be resolved:
+
+#. Optional external libraries are not found.
+#. Config flags for the dependent library are not enabled.
+#. Dependent driver modules are not installed on the system.
+
+To help find missing libraries, the user can specify addition search paths
+for those libraries as below:
+
+* Single path::
+
+      $ export LIBRARY_PATH=path
+
+* Multiple paths::
+
+      $ export LIBRARY_PATH=path1:path2:path3
+
+Some functionality may be disabled due to library headers being missed as part
+of the build. To specify an additional search path for headers at
+configuration time, use one of the commands below:
+
+*  Single path::
+
+       $ CFLAGS=-I/path meson build
+
+*  Multiple paths::
+
+       $ CFLAGS=-I/path1 -I/path2 meson build
+
+Below are some examples that show how to export libraries and their header
+paths.
+
+To specify a single library at a time::
+
+    $ export LIBRARY_PATH=/root/wireless_libs/zuc/
+    $ CFLAGS=-I/root/wireless_libs/zuc/include meson build
+
+To specify multiple libraries at a time::
+
+    $ export LIBRARY_PATH=/path/zuc/:/path/libsso_kasumi/build/
+    $ CFLAGS=-I/path/zuc/include \
+             -I/path/libsso_kasumi/include \
+	     meson build

Here and below, "testcases" should be split in two words.

Should be the same as above: <build_dir>

Do we really need to repeat above basic steps?
Would be easier to just reference another guide about meson.
I think doc/build-sdk-meson.txt should be moved to .rst.

Again, "build" is an example directory.

Would be worth to mention why meson or ninja can be used.

Grouping has changed recently.

Would be simpler to just list the suites.

Some quotes are missing to set multiple paths.

Why export is used for LIBRARY_PATH and not CFLAGS?
I think both variables can be exported or prepend the meson command?

The following section is a bit misleading.  The limitation on run time

Even better would be to provide a 1-liner that would dump the suites so
that new test suites wouldn't need to update the documentation.

Worth mentioning that you can run `meson test --list` to see a list of
all available tests

This doc helps to run UT, having basic steps in same page will help user to go through together and execute the same.
Just for few lines moving back and forth to different pages might be bit confusing.
Anyway still if you would prefer to remove these then only 2 sections will be available in this doc.
Please let us know if it is ok.

Thanks for the info. We observed that fast parallel test group is removed. 
Now we have four groups - fast, perf, driver, debug - all in non-parallel mode We will update the same.

CFLAGS given in meson command works and  also CFLAGS can be exported.
LIBRARY_PATH  cannot be prepended to meson command. We tried but it is not reflecting the required values.
Environment variables set using export is considered and not as command line args of meson command.


Will send the next version patch addressing these comments.

I think it is better to avoid repetition.

I am just saying that space-separated value require some quotes.

Please we need to understand why LIBRARY_PATH is not working
when preprended in the meson command.
Do you have more informations?

Rather than using the environment, one can also use "-Dc_args='...'
-Dc_link_args='...'" when calling meson.

Otherwise, I agree with Thomas, we should find out why the LIBRARY_PATH
doesn't work when passed in directly. I'm not aware of any reason it
shouldn't work.

As per our earlier analysis,  

LDFLAGS was not supported earlier in meson command.

find_library() is used to check whether the external dependency library exists or not in order to configure the build.
This function uses the standard system path to check existence of library, or else LIBRARY_PATH can be used as environment variable for custom paths.
LIBRARY_PATH is not supported directly (not a build configure option).

Only recently we can observe that LDFLAGS support is included in meson and linker options can be provided using LDFLAGS.
$ CFLAGS=-fsomething LDFLAGS=-Wl,--linker-flag meson <options>

Although LDFLAGS can be used and build configuration gets updated in LINK_ARGS,

'dependencies' option of static_library and shared_library() should be an object which is return value from dependency()/find_library().
Due to use of find_library() currently, we need to set the environment variable.

+
+Running DPDK Unit Tests with Meson
+==================================
+
+This section describes how to run test cases with the DPDK meson build system.
+
+Steps to build and run unit test cases using meson can be referred
+in :doc:`build-sdk-meson`
+
+Grouping of test cases
+----------------------
+
+Testcases have been grouped into four different groups.
+
+* Fast tests.
+* Performance tests.
+* Driver tests.
+* Tests which produce lists of objects as output, and therefore that need
+  manual checking.
+
+Testcases can be run in parallel or non-parallel mode using the ``is_parallel`` argument
+of ``test()`` in meson.build
+
+These tests can be run using the argument to ``meson test`` as
+``--suite project_name:label``.
+
+For example::
+
+    $ meson test --suite DPDK:fast-tests
+
+The project name is optional so the following is equivalent to the previous
+command::
+
+    $ meson test --suite fast-tests
+
+The meson command to list all available tests::
+
+    $ meson test --list
+
+
+Dealing with skipped test cases
+-------------------------------
+
+Some unit test cases have a dependency on external libraries, driver modules
+or config flags, without which the test cases cannot be run. Such test cases
+will be reported as skipped if they cannot run. To enable those test cases,
+the user should ensure the required dependencies are met.  Below are a few
+possible causes why tests may be skipped and how they may be resolved:
+
+#. Optional external libraries are not found.
+#. Config flags for the dependent library are not enabled.
+#. Dependent driver modules are not installed on the system.
+
+To help find missing libraries, the user can specify additional search paths
+for those libraries as below:
+
+* Single path::
+
+      $ export LIBRARY_PATH=path
+
+* Multiple paths::
+
+      $ export LIBRARY_PATH=path1:path2:path3
+
+Some functionality may be disabled due to library headers being missed as part
+of the build. To specify an additional search path for headers at
+configuration time, use one of the commands below:
+
+*  Single path::
+
+       $ CFLAGS=-I/path meson build
+
+*  Multiple paths::
+
+       $ CFLAGS=`-I/path1 -I/path2 meson build`
+
+Below are some examples that show how to export libraries and their header
+paths.
+
+To specify a single library at a time::
+
+    $ export LIBRARY_PATH=/root/wireless_libs/zuc/
+    $ CFLAGS=-I/root/wireless_libs/zuc/include meson build
+
+To specify multiple libraries at a time::
+
+    $ export LIBRARY_PATH=/path/zuc/:/path/libsso_kasumi/build/
+    $ CFLAGS=-I/path/zuc/include \
+             -I/path/libsso_kasumi/include \
+	     meson build

I think, It is good mention about the timeout and/or other valid(if any) UT parameter as well.

I think this is misleading. As far as I can see build-sdk-meson doesn't 
provide any details as to how to "run" test cases. I think you meant to 
say build-sdk-meson has the steps to build dpdk, or something among 
those lines

space between Test and cases.

I prefer not having to use the word 'group' twice in the same sentence, 
it just sounds awkward to me. I would do s/different groups/different 
test suites/

space between Test and cases.

I would also mention that by default all tests run serially for better 
stability

I would also somehow mention that these examples only work when your 
current working directory is the build directory. If you are not in the 
build directory you need to pass the -C flag, so like:

$ meson test -C <build path> --suite DPDK:fast-tests

the build path can either be a relative path or an absolute path, but I 
would skip this detail

#. Note enough processing cores. Some tests are skipped on machines with

+
+Running DPDK Unit Tests with Meson
+==================================
+
+This section describes how to run test cases with the DPDK meson build system.
+
+Steps to build and install DPDK using meson can be referred
+in :doc:`build-sdk-meson`
+
+Grouping of test cases
+----------------------
+
+Test cases have been classified into four different groups.
+
+* Fast tests.
+* Performance tests.
+* Driver tests.
+* Tests which produce lists of objects as output, and therefore that need
+  manual checking.
+
+These tests can be run using the argument to ``meson test`` as
+``--suite project_name:label``.
+
+For example::
+
+    $ meson test -C <build path> --suite DPDK:fast-tests
+
+If the ``<build path>`` is current working directory,
+the ``-C <build path>`` option can be skipped as below::
+
+    $ meson test --suite DPDK:fast-tests
+
+The project name is optional so the following is equivalent to the previous
+command::
+
+    $ meson test --suite fast-tests
+
+The meson command to list all available tests::
+
+    $ meson test --list
+
+Test cases are run serially by default for better stability.
+
+Arguments of ``test()`` that can be provided in meson.build are as below:
+
+* ``is_parallel`` is used to run test case either in parallel or non-parallel mode.
+* ``timeout`` is used to specify the timeout of test case.
+* ``args`` is used to specify test specific parameters.
+* ``env`` is used to specify test specific environment parameters.
+
+
+Dealing with skipped test cases
+-------------------------------
+
+Some unit test cases have a dependency on external libraries, driver modules
+or config flags, without which the test cases cannot be run. Such test cases
+will be reported as skipped if they cannot run. To enable those test cases,
+the user should ensure the required dependencies are met.  Below are a few
+possible causes why tests may be skipped and how they may be resolved:
+
+#. Optional external libraries are not found.
+#. Config flags for the dependent library are not enabled.
+#. Dependent driver modules are not installed on the system.
+#. Not enough processing cores. Some tests are skipped on machines with 2 or 4 cores.
+
+To help find missing libraries, the user can specify additional search paths
+for those libraries as below:
+
+* Single path::
+
+      $ export LIBRARY_PATH=path
+
+* Multiple paths::
+
+      $ export LIBRARY_PATH=path1:path2:path3
+
+Some functionality may be disabled due to library headers being missed as part
+of the build. To specify an additional search path for headers at
+configuration time, use one of the commands below:
+
+*  Single path::
+
+       $ CFLAGS=-I/path meson build
+
+*  Multiple paths::
+
+       $ CFLAGS=`-I/path1 -I/path2 meson build`
+
+Below are some examples that show how to export libraries and their header
+paths.
+
+To specify a single library at a time::
+
+    $ export LIBRARY_PATH=/root/wireless_libs/zuc/
+    $ CFLAGS=-I/root/wireless_libs/zuc/include meson build
+
+To specify multiple libraries at a time::
+
+    $ export LIBRARY_PATH=/path/zuc/:/path/libsso_kasumi/build/
+    $ CFLAGS=-I/path/zuc/include \
+             -I/path/libsso_kasumi/include \
+	     meson build

The last part about enabling some skipped test case is not correct.
Because this patch is very old, I apply it without this last part:
