Selenium Python - CI/CD Integration

Given the following pytest command in CI:

pytest -n 3 --maxfail=1

What will happen when one test fails?

ATests ignore failures and continue running

BAll tests stop immediately after the first failure

CTests run sequentially after failure

DOnly the failed test stops, others continue

Step-by-Step Solution

Solution:

Step 1: Understand the --maxfail option
The --maxfail=1 option tells pytest to stop scheduling new tests after the first failure. Workers finish their current test.
Step 2: Combine with parallel execution effect
With -n 3, the worker with the failed test stops it, but other workers continue and finish their current tests. No new tests are scheduled.
Final Answer:
Only the failed test stops, others continue -> Option D
Quick Check:
--maxfail=1 lets ongoing tests finish [OK]

Quick Trick: --maxfail=1 stops new tests after failure, ongoing continue [OK]
