[PATCH 0/7] refactor kvargs test

[PATCH 0/7] refactor kvargs test

[Chengwen Feng]

When developing patchset [1], I found the kvargs test is hard to 
understand when tried to add some testcase.

So refactor kvargs by:
1. introduce UT suite framework.
2. extract big test_valid_kvargs() to five part.

And add myself for voluntary maintenance of the kvargs library.

Note: to ensure patch independenct, new API which in patchset [1]
are not included in this patchset.

Chengwen Feng (7):
  app/test: introduce UT suite framework for kvargs
  app/test: extract basic token count testcase for kvargs
  app/test: extract without keys testcase for kvargs
  app/test: extract with keys testcase for kvargs
  app/test: extract parse list value testcase for kvargs
  app/test: extract parse empty elements testcase for kvargs
  maintainers: update for kvargs library

The test changes look good and it is always better to have more tests.

IANAL but starting the precedent of allowing adding copyright whenever a file
is touched just leads to lots of meaningless fluff.

OK, I sent v2 which remove this line.

[PATCH 2/7] app/test: extract basic token count testcase for kvargs

The test_valid_kvargs() function is too long to understand, extract

Hi Thomas,

  Could you please apply the commits 1~6 ? There commits are independent and could use for current code.

Thanks

[PATCH v2 0/7] refactor kvargs test

[Chengwen Feng]

When developing patchset [1], I found the kvargs test is hard to
understand when tried to add some testcase.

So refactor kvargs by:
1. introduce UT suite framework.
2. extract big test_valid_kvargs() to five part.

And add myself for voluntary maintenance of the kvargs library.

Note: to ensure patch independenct, new API which in patchset [1]
are not included in this patchset.

[PATCH v3 0/8] refactor kvargs test

[Chengwen Feng]

When developing patchset [1], I found the kvargs test is hard to
understand when tried to add some testcase.

So refactor kvargs by:
1. introduce UT suite framework.
2. extract big test_valid_kvargs() to five part.

And add myself for voluntary maintenance of the kvargs library.

[1] https://patchwork.dpdk.org/project/dpdk/cover/20231103073811.13196-1-fengchengwen@huawei.com/

Chengwen Feng (8):
  app/test: introduce UT suite framework for kvargs
  app/test: extract basic token count testcase for kvargs
  app/test: extract without keys testcase for kvargs
  app/test: extract with keys testcase for kvargs
  app/test: extract parse list value testcase for kvargs
  app/test: extract parse empty elements testcase for kvargs
  app/test: add process opt testcase for kvargs
  maintainers: update for kvargs library

---
v3: add rte_kvargs_process_opt()'s testcase.
v2: remove copyright line and add Stephen's ack.

[PATCH v4 0/7] refactor kvargs test

[Chengwen Feng]

When developing patchset [1], I found the kvargs test is hard to
understand when tried to add some testcase.

So refactor kvargs by:
1. introduce UT suite framework.
2. extract big test_valid_kvargs() to five part.
3. add new introduced rte_kvargs_process_opt() UT.

[1] https://patchwork.dpdk.org/project/dpdk/cover/20231103073811.13196-1-fengchengwen@huawei.com/

Chengwen Feng (7):
  app/test: introduce UT suite framework for kvargs
  app/test: extract basic token count testcase for kvargs
  app/test: extract without keys testcase for kvargs
  app/test: extract with keys testcase for kvargs
  app/test: extract parse list value testcase for kvargs
  app/test: extract parse empty elements testcase for kvargs
  app/test: add process opt testcase for kvargs

---
v4: remove maintainer commit.
v3: add rte_kvargs_process_opt()'s testcase.
v2: remove copyright line and add Stephen's ack.
