Selenium WebDriver Quality Control & Assurance 4

Question 1

What QA strategy validates that a new Selenium test suite correctly catches known defects by intentionally introducing bugs?

Accepted Answer

Mutation testing

Answer

Mutation testing modifies source code in small ways to verify the test suite detects the resulting defects.

Question 2

In Selenium test management, what is the purpose of tagging or categorizing tests with annotations like @Smoke or @Regression?

Accepted Answer

To selectively run specific subsets of tests based on context

Answer

Tags allow QA engineers to filter and run only relevant test subsets—like smoke tests after deployment or full regression before release.

Question 3

What is the primary quality risk of relying solely on XPath locators in a Selenium test suite?

Accepted Answer

XPath locators tied to DOM structure break easily when the UI is refactored

Answer

Brittle XPath expressions that depend on element position or parent hierarchy fail whenever developers restructure the HTML.

Question 4

Which Selenium WebDriver design pattern reduces test maintenance by abstracting interaction sequences into reusable methods?

Accepted Answer

Fluent interface / Action Builder

Answer

Fluent interfaces chain method calls to express complex interaction sequences clearly and allow reuse across tests.

Question 5

In QA reporting for Selenium suites, what does a high test execution time trend typically indicate?

Accepted Answer

Growing test suite size, environment slowdowns, or inefficient waits needing optimization

Answer

Rising execution times signal the need to parallelize tests, remove redundant waits, or optimize test data setup.
