pytest ignores test file if a single test method is called from the same test file #13240
Description
We want to execute all tests from a test file and need to execute one test from this file afterwards.
In version 7.3.1 this worked well.
Since 8.3.4 we imagine following:
Reproduction:
content of test_test.py
class TestClass(object):
def test_test_1(self):
print("Test1")
def test_test_2(self):
print("Test2")
def test_test_3(self):
print("Test3")
pytest -s test_test.py test_test.py::TestClass::test_test_3
Result:
============================= test session starts ==============================
platform linux -- Python 3.9.18, pytest-8.3.4, pluggy-1.5.0
rootdir: /tmp
plugins: dependency-0.6.0, csv-3.0.0
collected 1 item
test_test.py Test3
.
============================== 1 passed in 0.02s ===============================
What we expect is like in version 7.3.1:
pytest -s test_test.py test_test.py::TestClass::test_test_3
============================= test session starts ==============================
platform linux -- Python 3.9.18, pytest-7.3.1, pluggy-1.0.0

@bluetech could this be related to the directory handling

An other strange behavior:
test_test_1py
pytest -s -rsxX test_test.py::TestClass::test_test_1 test_test.py::TestClass::test_test_2 test_test.py::TestClass::test_test_3 test_test.py::TestClass::test_test_2 test_test_1.py

We missing the 2nd Test2.
Here the same behavior as in 7.3.1

We expect that the methods and files given as commandline arguments are executed as provided in comandline.

It is indeed, I was able to bisect the problem mentioned in the OP to:

Yes, this is a duplicate of the cursed issue #12083.
