Selenium WebDriver Risk Assessment & Management 4

Question 1

Which risk is introduced when Selenium tests are written with hard-coded Thread.sleep() calls instead of explicit waits?

Accepted Answer

Tests are unnecessarily slow or still fail if the page loads slower than the sleep duration

Answer

Hard-coded sleep values either waste time when pages load faster or cause failures when pages load slower than the fixed delay.

Question 2

A risk analysis shows that 30% of test failures are due to StaleElementReferenceException. What mitigation should be implemented?

Accepted Answer

Re-fetch elements after page interactions that trigger DOM updates

Answer

StaleElementReferenceException occurs when a cached element reference becomes invalid after DOM changes, so re-fetching elements after such actions resolves this.

Question 3

What risk does running Selenium tests in headless browser mode introduce compared to headed mode?

Accepted Answer

Some UI behaviors and rendering differences may not surface in headless mode

Answer

Headless browsers may render pages differently or skip GPU-accelerated effects, potentially hiding bugs that only manifest in full-rendering headed mode.

Question 4

In risk management terms, what is the consequence of not maintaining Selenium test data independently from application data?

Accepted Answer

Test data may be modified or deleted by the application, causing unpredictable failures

Answer

When test data is not isolated, application workflows can mutate or remove it, making test outcomes dependent on execution order and prior state.

Question 5

Which risk does Selenium Grid address in an enterprise testing strategy?

Accepted Answer

Risk of insufficient test coverage across browsers and operating systems

Answer

Selenium Grid distributes tests across multiple browser and OS combinations simultaneously, reducing the risk that browser-specific defects go undetected.
