Automation Testing Automation Functional Testing 2 — Questions and Answers
Question 1: Which type of locator is generally the most stable choice for identifying a web element in functional automation?
- A unique ID attribute (Correct answer)
- Absolute XPath from the root
- Element position index
- Inline CSS color value
Correct answer: A unique ID attribute
A unique ID is the fastest and least brittle locator because it is meant to be unique on the page.
Question 2: What is the primary purpose of an explicit wait in functional UI automation?
- Pause for a fixed time regardless of state
- Wait for a specific condition before proceeding (Correct answer)
- Speed up test execution
- Disable browser animations
Correct answer: Wait for a specific condition before proceeding
An explicit wait pauses only until a defined condition (like element visibility) is met.
Question 3: A test fails intermittently due to timing, passing on reruns. What is this commonly called?
- A blocker
- A flaky test (Correct answer)
- A smoke test
- A regression
Correct answer: A flaky test
Tests that pass and fail inconsistently without code changes are called flaky tests.
Question 4: Which design pattern separates page structure from test logic in functional automation?
- Singleton Pattern
- Page Object Model (Correct answer)
- Observer Pattern
- Factory Pattern
Correct answer: Page Object Model
The Page Object Model encapsulates page elements and actions, keeping tests cleaner and maintainable.
Question 5: What does a thread sleep (hard wait) most risk introducing into a test suite?
- Better reliability
- Wasted execution time and brittleness (Correct answer)
- Improved assertions
- Parallel execution
Correct answer: Wasted execution time and brittleness
Hard waits always pause the full duration, slowing suites and still failing if the element loads slower.
Question 6: In functional testing, what should an assertion primarily verify?
- The expected outcome of a behavior (Correct answer)
- The CPU usage of the browser
- The network bandwidth
- The number of test files
Correct answer: The expected outcome of a behavior
Assertions check that actual results match expected functional outcomes.
Question 7: Why is test data isolation important across automated functional tests?
- It makes reports prettier
- It prevents tests from affecting each other's results (Correct answer)
- It increases screen resolution
- It removes the need for assertions
Correct answer: It prevents tests from affecting each other's results
Isolated data ensures one test's changes do not cause another test to pass or fail unexpectedly.
