Section 2 Summary

Congratulations on completing the second section of this course!

In this section, you learned how to import necessary libraries for writing unit tests and how to test your code using unit testing.

You tested individual modules and also learned about various assertions that will allow you to easily test any of your code. Additionally, you discovered the Test-Driven Development (TDD) approach to programming, and who knows, maybe you've already decided to start programming using this approach.

In any case, you've done great work! With tests, your code will look much better and more professional.

4. Which of the following is true about Test-Driven Development (TDD)?

5. In JUnit, how are assertions used in a test method?

6. In JUnit, what is the purpose of the `@BeforeEach` annotation?

To validate that individual units of software work as intended.

To check the compatibility of the software with different operating systems.

To test the performance of the entire application.

What is a characteristic of a good unit test?

Виберіть правильну відповідь

It depends on other tests for data.

It tests multiple functionalities at once.

It is isolated and tests only one functionality.

Which of the following is true about Test-Driven Development (TDD)?

Виберіть правильну відповідь

Writing tests after writing the code

Writing tests before writing the code

Writing tests and code simultaneously

In JUnit, how are assertions used in a test method?

Виберіть правильну відповідь

To compare the expected output with the actual result

To check the speed of the code execution

To debug the application code

In JUnit, what is the purpose of the @BeforeEach annotation?

Виберіть правильну відповідь

To run a method before each test in a test class

To initialize test data after each test method

To declare a method that cleans up after all tests

What is the RED-GREEN-REFACTOR cycle in TDD?

Виберіть правильну відповідь

Write a failing test, make it pass, and then improve the code

Write a passing test, make it fail, and then refactor

Refactor the code, write a test, and make it pass
