Cypress - CI/CD and Reporting

ARun tests sequentially instead of parallel to avoid failures.

BDisable recording to speed up test runs and reduce flakiness.

CIncrease the number of parallel machines without changing tests.

DRefactor tests to be fully independent and avoid shared state or global data.

Step-by-Step Solution

Solution:

Step 1: Identify cause of flaky failures in parallel runs
Flaky failures often happen because tests share state or interfere with each other when run simultaneously.
Step 2: Choose best fix for flaky parallel tests
Refactoring tests to be independent and avoid shared global data ensures stable parallel execution.
Final Answer:
Refactor tests to be fully independent and avoid shared state or global data. -> Option D
Quick Check:
Independent tests fix flaky parallel runs [OK]

Quick Trick: Make tests independent to fix flaky parallel runs [OK]

Common Mistakes:

Just increasing machines without fixing tests
Disabling recording does not fix flakiness
Switching to sequential loses parallel benefits
