Selenium WebDriver Quality Control & Assurance 2 β Questions and Answers
Question 1: In Selenium test automation, what does the Page Object Model (POM) primarily improve?
- Test execution speed
- Code maintainability and reusability (Correct answer)
- Browser compatibility
- Network performance
Correct answer: Code maintainability and reusability
POM separates UI element locators from test logic, making tests easier to maintain when the UI changes.
Question 2: Which QA practice involves running Selenium tests automatically whenever code is committed to a repository?
- Manual regression testing
- Exploratory testing
- Continuous Integration (CI) (Correct answer)
- User acceptance testing
Correct answer: Continuous Integration (CI)
CI pipelines trigger automated Selenium tests on each commit to catch defects early in the development cycle.
Question 3: What is the purpose of using test data factories in Selenium QA frameworks?
- To speed up browser rendering
- To generate consistent and controlled test data programmatically (Correct answer)
- To manage WebDriver instances
- To handle browser downloads
Correct answer: To generate consistent and controlled test data programmatically
Test data factories create predictable, isolated data sets so tests do not depend on external or shared state.
Question 4: When performing cross-browser testing with Selenium, which tool allows you to run tests on multiple browsers simultaneously in the cloud?
- Selenium Grid (Correct answer)
- TestNG DataProvider
- Allure Report
- Maven Surefire Plugin
Correct answer: Selenium Grid
Selenium Grid distributes test execution across multiple nodes, each running different browsers or OS configurations.
Question 5: In Selenium QA, what is a 'flaky test'?
- A test that always fails
- A test that passes and fails inconsistently without code changes (Correct answer)
- A test with incorrect assertions
- A test that runs slower than expected
Correct answer: A test that passes and fails inconsistently without code changes
Flaky tests produce unreliable results due to timing issues, dynamic content, or environment instability.
Question 6: Which assertion strategy is recommended in Selenium test suites to provide the most detailed failure information?
- Using a single assert at the end of each test
- Using soft assertions to collect all failures before reporting (Correct answer)
- Skipping assertions and relying on screenshots
- Using only assertTrue for all checks
Correct answer: Using soft assertions to collect all failures before reporting
Soft assertions allow all verifications to run and report together, giving a complete picture of failures in one test run.
Question 7: What QA metric measures the percentage of application code exercised by your Selenium test suite?
- Defect density
- Test coverage (Correct answer)
- Mean time to repair
- Cyclomatic complexity
Correct answer: Test coverage
Test coverage (code coverage) indicates how much of the codebase is validated by automated tests, helping identify untested areas.
