Web Development Testing 3

Question 1

What is 'test flakiness' in the context of automated testing?

Accepted Answer

Tests that produce inconsistent pass/fail results without code changes

Answer

Flaky tests are non-deterministic — they sometimes pass and sometimes fail on the same code, often due to timing issues or shared state.

Question 2

In Cypress, what does `cy.intercept()` allow you to do?

Accepted Answer

Intercept and stub network requests made by the app under test

Answer

`cy.intercept()` lets you spy on, stub, or modify HTTP requests and responses at the network level during Cypress tests.

Question 3

Which of the following best describes 'smoke testing'?

Accepted Answer

A quick set of tests to verify the most critical features work before deeper testing

Answer

Smoke testing is a shallow, fast check that the build is stable enough for further testing — it confirms core functionality works.

Question 4

What does TDD (Test-Driven Development) require you to write first?

Accepted Answer

A failing test

Answer

TDD follows a red-green-refactor cycle: write a failing test first, then write the minimal code to make it pass, then refactor.

Question 5

Which Playwright method waits for a network response matching a URL before resolving?

Accepted Answer

page.waitForResponse()

Answer

`page.waitForResponse()` waits until a network response matching the given URL or predicate is received, preventing race conditions.
