The first test is run in skipped package

[zefirior]

Hi,
In my use case I need to skip all tests in some python package. For this purpose I added pytestmark to __init__.py:

# __init__.py
import pytest
pytestmark = pytest.mark.skip

I expect all tests to be skipped in this package. However, the first test in this package runs.

Here is a failed test for this issue:

def test_skip_package(testdir):
    testdir.makepyfile(
        __init__="""
        import pytest
        pytestmark = pytest.mark.skip
    """
    )

    testdir.makepyfile(
        """
        import pytest
        def test_skip1():
            assert 0
        def test_skip2():
            assert 0
    """
    )

    result = testdir.inline_run()
    _, skipped, _ = result.listoutcomes()
    assert len(skipped) == 2

just a heads up, I'm looking to revert this in #6197 (at least temporarily) as it caused some regressions

@blueyed found a way to fix this without revert

[asottile]

jk, we're reverting :)

@zefirior
As asked in #6197 (comment): aren't you supposed to have -o python_files to include the __init__.py (as a package)?
