Certified Agile Tester TDD Quiz

1. In the TDD red-green-refactor cycle, what does the 'red' phase represent?

Writing code that passes all tests

Writing a failing test before implementation

Refactoring code for clarity

Running code in production

2. In the TDD cycle, which phase involves writing just enough code to pass a test?

Red phase

Green phase

Refactor phase

Integration phase

3. What is test-driven development often abbreviated as?

TAD

TDD

TTD

DTT

4. In TDD, what should a test do before the implementation exists?

Pass successfully

Fail, indicating the feature is not yet built

Be skipped automatically

Execute against production code

5. What is the main difference between TDD and traditional development?

Tests are written after code is implemented

Tests are written before code is implemented

There is no difference

TDD does not require testing

6. Which testing framework is commonly used for Java TDD?

Jest

JUnit

Pytest

Mocha

7. In TDD, what is the purpose of continuous integration?

To merge code changes frequently and run automated tests

To prevent developers from writing code

To replace manual testing completely

To slow down the development process

8. What is a mock object used for in TDD?

To replace real dependencies during testing

To store test data permanently

To execute tests in production

To eliminate the need for unit tests

9. In TDD, what does a failing test initially indicate?

The implementation is complete

The test suite is broken

The required functionality has not yet been implemented

The code is ready for deployment

10. What is the primary benefit of writing tests before code in TDD?

Tests are easier to write

Code requirements are clarified upfront

It eliminates the need for code reviews

Development is always faster

11. Which of the following best describes the 'green' phase in TDD?

Writing a test that fails

Writing minimal code to make the test pass

Cleaning up and optimizing code

Deploying code to production

12. In TDD, when should tests be written?

After development is complete

During the refactoring phase only

Before writing the implementation code

Only when bugs are discovered

13. What is a unit test in the context of TDD?

A test that validates an entire application workflow

A test that checks a single component or function in isolation

A test performed by quality assurance teams

A test that runs only in production

14. Which phase of TDD involves improving code structure without changing functionality?

Red phase

Green phase

Refactor phase

Deploy phase

15. What is the primary goal of Test-Driven Development (TDD)?

Write all tests before any code

Ensure code quality by writing tests first, then implementation

Reduce the number of bugs in production

Eliminate manual testing entirely

16. True or False: TDD is incompatible with agile methodologies.

True

False

17. True or False: TDD requires writing 100% test coverage for all code.

True

False

18. True or False: In TDD, refactoring should only occur after all tests pass.

True

False

19. True or False: TDD eliminates the need for integration testing.

True

False

20. True or False: TDD can improve code maintainability and reduce technical debt.

True

False
