Test collection is not as expected when importing a static method from another test class

[uzibiton]

• a detailed description of the bug or problem you are having
  I have two files - test_file1.py & test_file2.py.
  In each of them a test class TestFile1 & TestFile2 and in each of the classes I have two tests.
  In class TestFile2 I have a static meth which I import to test_file1.py
  When running pytest on test_file1.py it collects 4 tests; two of them are correct and two are some storage combination.

test_file1.py::TestFile2::test_2_in_file2 & test_file1.py::TestFile2::test_1_in_file2 should not be there
I think if class TestFile2 had an autouse fixture it will also run it.
Please let me know if I am doing something wrong.
Thank you.

I don't see what's unexpected about this. You import TestFile2, so from pytest's point of view, it's just like the TestFile2 class was in test_file1.py as well.

I understand. Thanks
