Mockito Tutorial: Learn mocking with 25 Junit Examples - Step 06: @Before @After

The video tutorial explains the use of @Before and @After annotations in JUnit testing. It covers how to set up and tear down test environments using these annotations, demonstrating the process in Eclipse. The tutorial emphasizes the importance of understanding IDE functionalities for efficient coding and testing practices.

What is the primary purpose of using annotations like @Before and @After in JUnit tests?

• To handle exceptions during tests

• To generate test reports

• To set up and clean up test environments

• To manage test execution order

When creating a new JUnit test case in Eclipse, what is the recommended way to handle output messages?

• Use System.out.println for all messages

• Use a logging framework instead of System.out

• Use System.err for error messages

• Avoid any output messages

What does the @Before annotation do in a JUnit test?

• Executes only once before all tests

• Executes after each test method

• Executes before all test methods

• Executes before each test method

Why is it important to give meaningful names to methods annotated with @Before?

• To enhance performance

• To avoid compilation errors

• To ensure correct execution order

• To improve code readability

What is the typical use case for the @After annotation in JUnit tests?

• To log test results

• To execute tests in parallel

• To initialize test data

• To clean up resources after each test

How does the @After annotation help in managing resources?

• By creating new resources for each test

• By optimizing resource allocation

• By closing connections and cleaning up after tests

• By logging resource usage

What is a recommended practice for developers using an IDE like Eclipse or IntelliJ?

• To use only default settings

• To become an expert in using the IDE

• To avoid using shortcuts

• To write code without any IDE assistance
