You added the following to your pytest.ini but still get warnings about unknown marker 'api':

[markers]
api = marks tests as api

What is the most likely cause?

AMarkers must be registered in <code>conftest.py</code> instead

BThe marker name should be capitalized

CThe <code>pytest.ini</code> file is not in the test root directory

DThe marker description is missing

Step-by-Step Solution

Solution:

Step 1: Check pytest.ini location importance
Pytest reads pytest.ini only if it is in the root directory or above the tests.
Step 2: Evaluate other options
Marker names are case-sensitive but lowercase is valid. Registration in conftest.py is optional. Description can be empty but recommended.
Final Answer:
The pytest.ini file is not in the test root directory -> Option C
Quick Check:
pytest.ini location = no warnings [OK]

Quick Trick: Place pytest.ini in test root to register markers properly [OK]
