Why does Pycharm start a test when I name a function test_ - python-3.x

Question

Why does PyCharm suddenly wants to start a test?
My script is named 1_selection_sort.py And I'm trying to call the function test_selection_sort, and I'm just running with <current file> (Added in 2022.2.2 I assume).
I'm pretty sure this worked 24/10/2022 (Version 2022.2.2 and maybe 2022.2.3, but in 2022.2.4 it's no longer working).
Could someone please tell me when and why this was changed? Or maybe I did something wrong during installing?
My file is NOT named according to this naming scheme (https://docs.pytest.org/en/7.1.x/explanation/goodpractices.html#conventions-for-python-test-discovery):
In those directories, search for test_*.py
or *_test.py files, imported by their test
package name.
"""
Schrijf een functie selection_sort dat een lijst in dalende volgorde sorteert m.b.v. selection sort.
"""
def selection_sort(lijst):
for i in range(len(lijst)):
for j, number in enumerate(lijst):
if number < lijst[i]:
lijst[j] = lijst[i]
lijst[i] = number
return lijst
def test_selection_sort(lijst, check):
print(lijst)
result = selection_sort(lijst)
print(result)
print(check)
assert result == check
print("Begin controle selection_sort")
test_selection_sort([1, 3, 45, 32, 65, 34], [65, 45, 34, 32, 3, 1])
test_selection_sort([1], [1])
test_selection_sort([54, 29, 12, 92, 2, 100], [100, 92, 54, 29, 12, 2])
test_selection_sort([], [])
print("Controle selection_sort succesvol")

The solution I found was to disable Pytest following this answer: https://stackoverflow.com/a/59203776/13454049
Disable Pytest for you project
Open the Settings/Preferences | Tools | Python Integrated Tools settings dialog as described in Choosing Your Testing Framework.
In the Default test runner field select Unittests.
