Selenium WebDriver Quality Control & Assurance 3

Question 1

In Selenium automation quality, what does the 'test pyramid' concept recommend regarding UI tests?

Accepted Answer

UI tests should be the fewest, sitting at the top of the pyramid

Answer

The test pyramid advises keeping UI/end-to-end tests minimal because they are slow and costly to maintain compared to unit tests.

Question 2

Which Selenium technique helps prevent test failures caused by elements not yet visible in the DOM?

Accepted Answer

Explicit waits with ExpectedConditions

Answer

Explicit waits poll for a specific condition like element visibility, making tests resilient without arbitrary sleep delays.

Question 3

In a QA pipeline, what is the role of a Selenium smoke test suite?

Accepted Answer

To verify that the most critical paths work after a new deployment

Answer

Smoke tests quickly validate core functionality, confirming a build is stable enough for more thorough testing.

Question 4

What is the main quality benefit of using parameterized tests in a Selenium framework?

Accepted Answer

They allow a single test to run with multiple data sets, improving coverage

Answer

Parameterization lets one test method validate multiple input scenarios, increasing breadth without duplicating test code.

Question 5

Which practice ensures Selenium tests remain independent and do not affect each other's outcomes?

Accepted Answer

Setting up and tearing down state for each test individually

Answer

Test isolation via @BeforeEach/@AfterEach setup and teardown prevents state leakage between tests, ensuring reliable results.
