Which filename pattern will pytest automatically detect as a test module when scanning a directory?
Atest_example.py
Bexample_test.py
Cexample.py
DTestExample.py
Step-by-Step Solution
Solution:

  1. Step 1: Understand pytest naming conventions

    pytest by default recognizes files starting with test_ or ending with _test.py as test modules.

  2. Step 2: Analyze each option

    • test_example.py starts with test_ so pytest detects it.
    • example_test.py ends with _test.py which is also valid and detected by pytest.
    • example.py does not follow naming conventions.
    • TestExample.py uses uppercase and does not start with test_.

  3. Final Answer:

    test_example.py and example_test.py -> Option A

  4. Quick Check:

    File must start with test_ or end with _test.py [OK]
