Selenium WebDriver Risk Assessment & Management 2 β Questions and Answers
Question 1: A Selenium test suite takes 4 hours to run but the CI pipeline must complete in 1 hour. Which risk mitigation strategy is most appropriate?
- Delete slow tests permanently
- Parallelize tests across multiple browser instances (Correct answer)
- Skip the failing tests
- Run tests only on weekends
Correct answer: Parallelize tests across multiple browser instances
Parallelizing tests across multiple browser instances reduces total execution time without sacrificing test coverage.
Question 2: Which scenario represents the highest risk when using implicit waits in Selenium WebDriver?
- Tests run slightly slower than necessary
- Tests pass on fast machines but fail on slow CI servers (Correct answer)
- Browser window size affects element visibility
- Driver version mismatches cause exceptions
Correct answer: Tests pass on fast machines but fail on slow CI servers
Implicit waits set a global timeout that may be sufficient locally but inadequate on slower CI infrastructure, causing environment-dependent failures.
Question 3: A risk register for a Selenium automation project should include which of the following for each identified risk?
- Only the risk description
- Risk description, probability, impact, and mitigation plan (Correct answer)
- Risk description and the developer responsible
- Only risks with high probability
Correct answer: Risk description, probability, impact, and mitigation plan
A complete risk register entry captures the risk description, its likelihood, potential impact, and the planned mitigation to enable prioritization.
Question 4: Your Selenium tests rely on a third-party payment gateway sandbox that has 99% uptime. What is the recommended risk mitigation?
- Remove payment tests from the suite
- Mock the payment gateway for automated tests (Correct answer)
- Run tests only during business hours
- Use real production credentials for testing
Correct answer: Mock the payment gateway for automated tests
Mocking the third-party dependency eliminates external uptime risk while preserving test coverage of the application logic.
Question 5: Which ChromeDriver version management risk is most commonly encountered in Selenium projects?
- ChromeDriver consuming too much RAM
- ChromeDriver version mismatch with installed Chrome browser (Correct answer)
- ChromeDriver lacking headless mode support
- ChromeDriver not supporting JavaScript execution
Correct answer: ChromeDriver version mismatch with installed Chrome browser
Chrome auto-updates frequently, and a mismatch between the Chrome browser version and ChromeDriver version causes SessionNotCreatedException errors.
Question 6: A team notices that 20% of Selenium tests produce intermittent failures without code changes. What risk category does this represent?
- Performance risk
- Test flakiness risk (Correct answer)
- Security risk
- Compatibility risk
Correct answer: Test flakiness risk
Intermittent test failures without code changes are classified as flakiness risk, which erodes trust in the test suite and masks real defects.
Question 7: When assessing risk for Selenium tests that interact with dynamically loaded Angular content, which risk factor is primary?
- Network bandwidth limitations
- Asynchronous rendering causing element not found exceptions (Correct answer)
- Browser memory usage spikes
- SSL certificate validation failures
Correct answer: Asynchronous rendering causing element not found exceptions
Angular apps render content asynchronously, so elements may not exist in the DOM when Selenium attempts to interact with them, causing NoSuchElementException.
