Selenium WebDriver Research & Evidence-Based Practice 4

Question 1

Research on test data management in Selenium automation recommends which approach for maintaining test isolation?

Accepted Answer

Creating fresh, independent test data before each test and tearing it down afterward

Answer

Independent test data prevents cross-test contamination and makes tests deterministic regardless of execution order.

Question 2

Studies on Selenium Grid architecture recommend using Docker-based nodes over static VMs primarily because:

Accepted Answer

Containers enable on-demand provisioning and clean-state reset between test runs

Answer

Docker containers can be spun up on demand and discarded after each test run, ensuring consistent clean browser state and elastic scaling.

Question 3

Evidence-based performance testing practice distinguishes Selenium from tools like k6 or JMeter by recognizing that Selenium is best suited for:

Accepted Answer

Measuring real browser rendering performance from a user's perspective

Answer

Selenium drives real browsers, so it captures end-to-end user-perceived performance including rendering and JavaScript execution time.

Question 4

Research on Selenium test failure categorization recommends classifying failures into 'product bugs' vs. 'test bugs' because:

Accepted Answer

It enables accurate calculation of automation effectiveness vs. test code quality

Answer

Separating failure types reveals whether failures represent real defects or poor test implementation, guiding where improvement effort should go.

Question 5

The 'Living Documentation' concept in BDD with Selenium Cucumber is considered evidence-based because:

Accepted Answer

Feature files written in Gherkin serve as both executable tests and human-readable specifications that stay synchronized

Answer

Gherkin scenarios are both the specification and the test, so documentation cannot drift from implementation because they are the same artifact.
