PyTest - Markers

You have tests marked as api, ui, and db. You want to run tests that are either api or ui, but not db. Which command achieves this?

Apytest -m "api or (ui and not db)"

Bpytest -m "api or ui and not db"

Cpytest -m "(api or ui) and not db"

Dpytest -m "api and ui and not db"

Step-by-Step Solution

Solution:

Step 1: Understand operator precedence
Logical AND has higher precedence than OR, so parentheses are needed to group api or ui together.
Step 2: Analyze each option
pytest -m "(api or ui) and not db" correctly groups (api or ui) and excludes db with and not db.
Final Answer:
pytest -m "(api or ui) and not db" -> Option C
Quick Check:
Use parentheses to group OR conditions = A [OK]

Quick Trick: Use parentheses to group markers with OR before AND [OK]
