Selenium Testing Framework Quality Control & Assurance 4

Question 1

In Selenium QA, what is the purpose of a 'test retry mechanism'?

Accepted Answer

To re-run failed tests a defined number of times to filter out transient environment failures from real defects

Answer

Retry logic reduces false failures from intermittent issues like network blips while still surfacing consistently reproducible defects.

Question 2

What does 'headless browser testing' offer from a QA efficiency standpoint?

Accepted Answer

Faster test execution and resource savings since no GUI is rendered, useful in CI environments

Answer

Headless browsers skip rendering the visual UI, reducing CPU/memory overhead and speeding up test runs in headless CI servers.

Question 3

Which Selenium practice reduces test fragility caused by synchronization issues without using fixed waits?

Accepted Answer

Using WebDriverWait with ExpectedConditions for explicit, condition-based waiting

Answer

Explicit waits poll for a specific condition like element visibility, adapting to actual load time rather than guessing a fixed delay.

Question 4

In a QA context, what is 'regression testing' as applied to Selenium automation?

Accepted Answer

Re-running existing automated tests after code changes to verify no previously working functionality is broken

Answer

Regression testing ensures new code changes haven't inadvertently broken existing features that previously passed.

Question 5

What is the risk of having too many Selenium end-to-end tests compared to unit tests, according to the Test Pyramid?

Accepted Answer

A top-heavy pyramid leads to slow, brittle, expensive-to-maintain test suites

Answer

The Test Pyramid recommends a broad base of fast unit tests and a narrow top of slow E2E tests; inverting this creates a fragile, slow suite.
