Re: [dts] [PATCH V1 2/2][vhost gro] tests: add testsuite vhost gro

[Tu, Lijuan]

1, why the file name is different with the class name? basically,  the suite name is the file name
2, if your suite name is same as your config file name , the framework will load configuration, so there is no need to parse configuration file at test suite level.
For example:
If your suite file is TestSuite_dpdk_gro_lib.py, your configuration file should be dpdk_gro_lib.cfg.
And your class name should be" TestDPDKGROLib"

Re: [dts] [PATCH V1 2/2][vhost gro] tests: add testsuite vhost gro

[Ma, LihongX]

Hi,lijuan
agree with you, and I will optimization code with gro , gso and exception path on later.

1, why the file name is different with the class name? basically,  the suite name is the file name 2, if your suite name is same as your config file name , the framework will load configuration, so there is no need to parse configuration file at test suite level.
For example:
If your suite file is TestSuite_dpdk_gro_lib.py, your configuration file should be dpdk_gro_lib.cfg.
And your class name should be" TestDPDKGROLib"
