Mockito Tutorial: Learn mocking with 25 Junit Examples - Step 10: Mockito Annotations - @Mock, @InjectMocks, @RunWith, @

The video tutorial explains how to use various Mockito annotations to create readable and maintainable tests. It covers the use of @Mock, @InjectMocks, and ArgumentCaptor annotations, demonstrating how they simplify the process of mocking dependencies and capturing arguments. The tutorial highlights the benefits of using these annotations, such as reducing code lines and improving test readability, allowing developers to focus on business logic rather than setup infrastructure.

What is the primary purpose of using annotations in Mockito?

• To eliminate the need for any test assertions

• To make tests more readable and maintainable

• To increase the number of lines in the test code

• To complicate the test setup

Which annotation is used to create mock objects in Mockito?

• @Mock

• @RunWith

• @Captor

• @InjectMocks

What does the @Mock annotation help eliminate in test methods?

• The need for test execution

• The need for test data

• The need for manual mock object creation

• The need for assertions

How does the @InjectMocks annotation benefit test setup?

• By eliminating the need for any dependencies

• By creating real instances of dependencies

• By removing all dependencies

• By automatically injecting mock dependencies

What is the effect of using @InjectMocks on the number of lines in a test class?

• It increases the number of lines

• It doubles the number of lines

• It has no effect on the number of lines

• It reduces the number of lines

What is a key advantage of using annotations in tests?

• They eliminate the need for any test logic

• They enhance test readability and focus on business logic

• They focus on the infrastructure rather than business logic

• They make tests harder to read

What does the @Captor annotation help create?

• Real instances

• Argument captors

• Mock objects

• Test data

How does the @Captor annotation improve test verification?

• By eliminating the need for verification

• By creating mock objects

• By capturing arguments for method calls

• By creating real instances

What is the main focus when using annotations in tests?

• Test data creation

• Test execution speed

• Business logic

• Infrastructure setup

Which runner is used with Mockito to enable annotations?

• Spring Runner

• TestNG Runner

• Mockito JUnit Runner

• JUnit Runner
