Which of these is a common challenge associated with unit tests?
Available answers
While unit tests are valuable, they can be time-consuming to write initially, especially for complex logic. However, they save time in the long run by catching bugs early.
Question 5/15

answer was incorrect
What role does 'assertion' play in a unit test?
Available answers
An assertion in a unit test checks if certain conditions are met. If an assertion fails, the test fails.
Question 6/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
What trait is NOT desirable for a unit test?
Available answers
Unit tests should be isolated and not depend on external systems, ensuring they test only the intended unit of code.
Question 7/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
What does 'mocking' mean in the context of unit testing?
Available answers
Mocking involves creating fake objects that mimic the behavior of real objects to test interactions in isolation.
Question 8/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
Which of the following should be avoided in unit tests?
Available answers
Real databases should be avoided in unit tests to ensure the tests remain fast, isolated, and independent of external systems.
Question 9/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
What does a successful unit test execution typically indicate?
Available answers
A successful unit test indicates that the unit of code works as expected for the specific test cases provided.
Question 10/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
When using mocks in unit tests, what is the primary advantage?
Available answers
Mocks simulate interactions with dependencies, allowing the unit test to remain focused on the unit itself without involving external systems.
Question 11/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
What is the primary goal of unit testing?
Available answers
Unit testing focuses on testing individual components (or units) to ensure they function correctly in isolation.
Question 12/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
Which statement is true about the test-driven development (TDD) approach?
Available answers
TDD involves writing tests before writing the actual code, guiding the development process to ensure each unit behaves as expected.
Question 13/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
Which of the following is NOT a benefit of unit testing?
Available answers
Unit testing does not replace manual testing completely; it complements other testing methods but does not eliminate the need for manual testing.
Question 14/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
What is code coverage in relation to unit testing?
Available answers
Code coverage measures the percentage of code that is executed by the test cases, indicating which parts of the code are tested.
Question 15/15
😊 Your
answer was correct
🙁 Your
answer was incorrect
What is a common characteristic of a poorly written unit test?
Available answers
A poorly written unit test is typically one that is not easy to read and understand, making it difficult to maintain and trust.
