Selenium Testing Framework Risk Assessment & Management 4 — Questions and Answers
Question 1: Which risk does implementing a retry mechanism for flaky Selenium tests help manage?
- Browser version mismatch risk
- Transient environmental failure risk masking real bugs (Correct answer)
- Locator maintenance risk
- Parallel execution race conditions
Correct answer: Transient environmental failure risk masking real bugs
Retries handle transient network or timing glitches but must be carefully limited so they do not hide genuine defects by masking consistent failures.
Question 2: A Selenium test suite has no screenshots or video capture on failure. What risk does this create?
- Tests will not execute in parallel
- Difficult root-cause analysis, increasing mean time to diagnose failures (Correct answer)
- The WebDriver will not start
- Test reports cannot be generated
Correct answer: Difficult root-cause analysis, increasing mean time to diagnose failures
Without visual artifacts on failure, developers must reproduce the environment manually, dramatically increasing diagnosis time and effort.
Question 3: Which risk is introduced by not versioning or tagging your Selenium test suite alongside application releases?
- Grid nodes will reject the test runner
- Test suites may be run against incompatible application versions, causing false failures (Correct answer)
- The browser will reject WebDriver commands
- CI pipelines cannot detect test files
Correct answer: Test suites may be run against incompatible application versions, causing false failures
Unversioned test suites can be executed against application builds they were not designed for, producing misleading failure reports.
Question 4: What is the primary risk when Selenium test data is not isolated between test runs?
- WebDriver sessions will expire
- Data left over from previous runs can cause cascading failures in subsequent tests (Correct answer)
- Browser memory usage will increase
- CSS selectors will stop matching
Correct answer: Data left over from previous runs can cause cascading failures in subsequent tests
Non-isolated test data allows dirty state from one run to interfere with assertions in later runs, making test results unreliable.
Question 5: Which risk does a Selenium test suite face when the application under test uses heavy client-side rendering frameworks like React or Angular?
- WebDriver cannot open these pages at all
- Elements may not be in the DOM when the test tries to interact with them (Correct answer)
- Headless mode is not supported
- Page Object Model cannot be applied
Correct answer: Elements may not be in the DOM when the test tries to interact with them
SPAs render content asynchronously, so elements may not exist or be interactive when Selenium queries the DOM, requiring robust explicit waits.
Question 6: What risk management technique involves categorizing Selenium tests as smoke, regression, or sanity suites?
- Test parallelization
- Risk-based test prioritization (Correct answer)
- Data-driven testing
- Boundary value analysis
Correct answer: Risk-based test prioritization
Risk-based prioritization ensures high-impact, high-probability failure paths (smoke/sanity) are tested first, limiting exposure when time is constrained.
Question 7: A Selenium test intermittently fails only in the CI environment but never locally. What risk factor should be investigated first?
- Local machine screen resolution
- Environmental differences such as browser version, screen size, or network latency in CI (Correct answer)
- Page Object Model design
- Java heap size on the developer laptop
Correct answer: Environmental differences such as browser version, screen size, or network latency in CI
CI environments often differ from local machines in browser version, viewport size, and network conditions, all of which can trigger environment-specific failures.
