Pytest: py.test not running all test by selected marks

[BoazWarshawsky]

My problem is that py.test ignoring few tests that having marks (@pytest.mark.some_mark).

I have a folder named featureapp that contain 2 python files:
example_test.py and zapp_sanity.py.
Each python file contains few classes with few tests inside, in addition each file has 1 class that has the pytest mark of: @pytest.mark.zapp_sanity

My terminal command line for running the tests is:
py.test feature_app/ -m "zapp_sanity" -v -s --basetemp=. --color=yes

Actual Results for the run is that only the tests classes in example_test.py are executed and the tests in file zapp_sanity.py are ignored

In addition, I also tried giving to each of the different classes in the different files, a different marks:
@pytest.mark.zapp_2
@pytest.mark.zapp_1
And then running this line:
py.test feature_app/ -m "zapp_1 or zapp_2" -v -s --basetemp=. --color=yes

But it did not work :(

pytest by default doesn't look for tests in files not named like test_*.py

also using --basetemp=. actually does a rm -rf . so that's def not a good idea, we should warn about that

[BoazWarshawsky]

Thanks @RonnyPfannschmidt,
Matter of fact the tests that did executed successfully were the ones in example_test.py,
anyway I renamed example_test.py to be example.py and now none of the tests run:
=============================================================== no tests ran in 0.02 seconds ================================================================

[BoazWarshawsky]

@RonnyPfannschmidt, ok!
I just read again you answer,
I renamed my files to be:
test_zapp_sanity.py
test_example.py

and my problem solved!
:)

we can close the ticket, * the solution is to have the prefix of test_ for each python file **, like you said
