PyTest - Markers

You have tests marked db, api, and slow. You want to run tests that are either db or api but never slow. Which command is correct?

Apytest -m '(db or api) and not slow'

Bpytest -m 'db or api and not slow'

Cpytest -m 'db and api and not slow'

Dpytest -m 'db or api or not slow'

Step-by-Step Solution

Solution:

Step 1: Understand operator precedence and grouping
Parentheses group 'db or api' to run tests with either marker.
Step 2: Exclude 'slow' tests with 'and not slow'
The expression runs tests with 'db' or 'api' but excludes those marked 'slow'.
Final Answer:
pytest -m '(db or api) and not slow' -> Option A
