[issue12231] regrtest: add -k and -K options to filter tests by function/file names

Antoine Pitrou  added the comment:

This patch doesn't work if run_unittest() is called with an already constructed 
test suite or test case (the patch in #12626 does).

regrtest_regex-2.patch: minor update, just ensure that the patch applies

> How about reusing unittest discovery in regrtest?

Does this feature support filtering by keyword for file names and function 
names?

+1 to what Ezio said, though I'd rather have this than not have the 
functionality at all :)

[issue12231] regrtest: add -k and -K options to filter tests by function/file names

[Ezio Melotti]

Ezio Melotti  added the comment:

IMHO it would be better to tweak regrtest so that it understand 
test_file.TestClass.test_method, possibly supporting wildcards.
E.g.:
  - ./python -m test test_subprocess.POSIXProcessTestCase
  - ./python -m test test_subprocess.POSIXProcessTestCase.test_pass_fds
  - ./python -m test '*codecencoding*'
  - ./python -m test 'test_subprocess.C*'

The -x/--exclude option could be extended to support this notation too and make 
possible to exclude specific tests classes/methods.
Wildcards are less flexible than regex, but I think they are good enough for 
our use case and simpler to use.

We need maybe a third option to filter tests by their class name. And we need 
also maybe the opposite option: exclude tests matching a regex. Another 
proposition: --include and --exclude options using the following format:

::

Each field is optional, examples:

--include "test_subprocess::leak" ignores test_leak function of 
test_subprocess file
--include "codecencoding::" runs the 6 test_codecencoding* files
--include "test_subprocess:^C:" runs only the tests of the io module (not the 
_pyio module)
- etc.

Problem: --exclude (-x) option is already used.

[issue12231] regrtest: add -k and -K options to filter tests by function/file names

[STINNER Victor]

New submission from STINNER Victor :

Attached patch adds -k/--func-regex and -K/--file-regex options to filter tests 
by function/file names. It modifies makeSuite() and getTestCaseNames() 
functions of unittest.loader to add an optional filter argument: callback 
taking a function name as argument and returning False if the test should be 
ignored. You can use the new options more than once and their argument are 
regular expressions (case insensitive).

Examples:

- "./python -m test -k subprocess -K pass_fds" runs only 1 function of 1 file: 
test_subprocess.test_pass_fds()
- "./python -m test -k os$" runs 1 file: test_os
- "./python -m test -K codecencoding" runs 6 files: test_codecencodings_cn, 
test_codecencodings_hk, test_codecencodings_iso2022, test_codecencodings_jp, 
test_codecencodings_kr, test_codecencodings_tw
