What this covers
Flaky Tests appears throughout Automation Testing interviews. At hard level, interviewers are typically checking depth under pressure — edge cases, failure modes, performance characteristics, and the trade-offs you accepted. Work through these, then explain your answer out loud; the second part is what interviews actually test.
4 example questions
1. Which of the following statements about Flaky Tests is FALSE?
- A. Quarantining flaky tests keeps them visible while preventing them from blocking releases.
- B. A flaky test fails consistently every single run.correct
- C. Test data collisions in shared environments cause intermittent failures under parallel runs.
- D. Shared mutable state between tests causes order-dependent failures.
Why: The selected statement is false. The other options are accurate statements about Flaky Tests.
