Question 1 of 631

Which two concepts describe test-driven development? (Choose two.)

Answer choices
Show answer

Correct answers: B, E

Test-driven development (TDD) is a software development methodology that involves writing a test before writing the actual code. This ensures that the code is tested incrementally and helps in refining and improving it through continuous refactoring. By following these steps, TDD facilitates the creation of clean, efficient, and bug-free code. Therefore, enabling code refactoring and writing a test before writing code are two key concepts that describe TDD.

Question 2 of 631

Which task is performed because the test-driven development approach is being used?

Answer choices
Show answer

Correct answer: C

In test-driven development (TDD), the process involves writing tests before writing the actual code. Once the test is written and fails (because the functionality is not yet implemented), the developer writes the minimum amount of code required for the test to pass. After the test passes, the code is then refactored to ensure it is clean and efficient while still passing the tests. The task of refactoring code that is covered by existing tests aligns with the principles of TDD, as it involves refining the code after it has already been tested to ensure it meets all requirements and maintains readability and structure without changing its behavior.

Question 3 of 631

What is the FIRST development task in test-driven development?

Answer choices
Show answer

Correct answer: B

In test-driven development (TDD), the first development task is to write a failing test case for the desired function. This initial test case is intended to define the function's expected behavior before any actual implementation code is written, ensuring that the code development follows the requirements specified by the test. Only after writing this failing test and seeing it fail does the developer proceed to write the minimum amount of code necessary to make the test pass.

Question 4 of 631

In test-driven development, what are two of the green bar patterns? (Choose two.)

Answer choices
Show answer

Correct answers: C, E

In test-driven development (TDD), two recognized green bar patterns are 'triangulate' and 'fake it'. 'Triangulate' refers to the method of using multiple tests to drive the design of the code, while 'fake it' is about implementing simple code that makes the test pass in the simplest way possible. These patterns help ensure that the code evolves incrementally and maintains a clear focus on passing tests while gradually improving the implementation.

Question 5 of 631

In the test-driven development model, what is changed after a test fails?

Answer choices
Show answer

Correct answer: C

In the test-driven development model, after a test fails, the code is changed. This is because the primary purpose of test-driven development is to write the minimum amount of code necessary to pass the failing test. The process involves writing a test that initially fails, then writing the code to make the test pass, followed by refactoring the code if necessary. Therefore, the correct answer is that the code is changed.

Stories from the certified

May 11, 2026
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.

Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.

Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.

Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.

The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.

I don't usually leave reviews, but this one felt worth sharing. The questions were quite close to what actually appeared on the exam, more than I expected. I spent about a week going through the material before my test, and it helped me feel more prepared.
