getting list of added tests ?

Is there a way to recover the list of tests that were added by a call to pytest_discover_tests ?

The tests I'm dealing with do need some extra env variable(s) to be set, and from what I see in the implementation there's no way to inject more ENVIRONMENT besides PYTHONPATH and XXLD_LIBRARY_PATH, am I correct ?

So getting a list of added tests would allow to call set_property(TEST ... APPEND PROPERTY ENVIRONMENT SOMEVAR=...) afterwards.

Hi @aphecetche, apologize for the very late reply!

I'm actually working on adding an ENVIRONMENT option for the pytest_discover_tests, so that extra environment variables could be added as follows:

pytest_discover_tests(
    PythonTest
    ...
    ENVIRONMENT
        "ENV1=TEST1"
        "ENV2=TEST2"
)

I'll update this thread once I have a PR ready!

getting a list of added tests would allow to call set_property(TEST ... APPEND PROPERTY ENVIRONMENT SOMEVAR=...) afterwards.

The tests are created via a separated CMake scripts, discovered via the TEST_INCLUDE_FILES variable, so I'm not sure it would be possible to propagate a variable with all added tests. I'll do some testing and will get back to you.

So, it isn't possible to set a CMake variable from the executed script, so I don't see an easy way to retrieve the list of added test so that it can be processed afterwards.

However, I have a working prototype with the ENVIRONMENT argument that I will release shortly: #15

Please reopen the ticket is it doesn't work as expected!
