PyTest - Test Organization

You want pytest to discover tests in a file named mytests.py containing functions def test_one(): and def test_two():. By default, pytest does not find this file. How can you rename the file to follow pytest discovery rules without changing function names?

ARename to my_test_s.py

BRename to mytestsTest.py

CRename to testmytests.py

DRename to test_mytests.py

Step-by-Step Solution

Solution:

Step 1: Recall pytest file discovery naming
pytest finds files starting with 'test_' or ending with '_test.py'.
Step 2: Check options for correct naming
'test_mytests.py' starts with 'test_' [check]. 'mytestsTest.py' ends with 'Test.py' (uppercase 'T' not matching lowercase 'test'). 'testmytests.py' lacks '_' after 'test'. 'my_test_s.py' does not start with 'test_' or end with '_test.py'. Only the first option works.
Final Answer:
Rename to test_mytests.py -> Option D
Quick Check:
File starts or ends with 'test' = test_mytests.py [OK]

Quick Trick: File must start or end with 'test' exactly [OK]

MISTAKES

Removing 'test' from file name
