Question 1/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is the drawback of using TDD in software development?

Available answers

A potential drawback of TDD is that it can be time-consuming to write tests before code, especially at the beginning of a project.
Question 2/15
😊 Your answer was correct 🙁 Your answer was incorrect
What should happen immediately after a developer writes a failing test in TDD?

Available answers

After writing a failing test in TDD, the next step is to write the simplest code that can make the test pass.
Question 3/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which role does TDD play in agile development environments?

Available answers

In agile environments, TDD aligns with iterative and incremental development by ensuring continuous testing and instant feedback, making it easier to accommodate changing requirements.
Question 4/15
😊 Your answer was correct 🙁 Your answer was incorrect
How does TDD impact code design?

Available answers

TDD inherently promotes better design because it requires developers to break down their code into smaller, manageable, and testable pieces, which often results in cleaner design.
Question 5/15
😊 Your answer was correct 🙁 Your answer was incorrect
What benefit does TDD have with respect to understanding software requirements?

Available answers

TDD can enhance understanding of requirements because writing tests prior to coding forces developers to clarify and define the expected outcomes based on those requirements.
Question 6/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is the primary goal of test-driven development (TDD)?

Available answers

TDD primarily aims to reduce defects by writing tests prior to writing the actual code, ensuring that the code meets the specified requirements and works correctly.
Question 7/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is a 'mock' in the context of TDD?

Available answers

A 'mock' is a simulated object that mimics the behavior of real objects in a controlled way, often used in unit testing to isolate the system under test.
Question 8/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is an anti-pattern in the context of TDD?

Available answers

An anti-pattern in TDD is testing after the complete implementation is done, which contradicts the core practice of writing tests before code.
Question 9/15
😊 Your answer was correct 🙁 Your answer was incorrect
Why is continuous integration beneficial when used alongside TDD?

Available answers

Continuous integration provides immediate feedback on test outcomes, ensuring that any new code changes do not break existing tests, which complements TDD practices.
Question 10/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is the primary focus of tests in the TDD approach?

Available answers

The primary focus of tests in TDD is to verify that the code behaves as expected and meets the defined requirements.
Question 11/15
😊 Your answer was correct 🙁 Your answer was incorrect
What constitutes a 'unit' in unit testing within the TDD approach?

Available answers

In TDD, a 'unit' refers to the smallest testable part of an application, typically a single function or method.
Question 12/15
😊 Your answer was correct 🙁 Your answer was incorrect
In TDD, what should be done if a test continues to fail after writing sufficient code?

Available answers

If a test continues to fail, the developer should review both the test itself and the code logic to find and fix the error.
Question 13/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which of the following is NOT a direct outcome of using TDD?

Available answers

Automated acceptance testing is not a direct outcome of TDD. TDD focuses more on unit tests and immediate observed behavior of the units rather than acceptance criteria from the customer's perspective.
Question 14/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which type of testing is NOT directly a focus of TDD?

Available answers

TDD primarily focuses on unit testing and regression testing through consistently running tests, but does not specifically address performance testing.
Question 15/15
😊 Your answer was correct 🙁 Your answer was incorrect
How does TDD help in maintaining backward compatibility?

Available answers

TDD uses automated tests to ensure that existing functionality continues to work as new features are added, thus maintaining backward compatibility.
