The Purpose of @Before and @After Annotations in JUnit Testing

When it comes to JUnit testing, the focus keyword is important for understanding the setup and teardown process of test cases. The @Before and @After annotations play a crucial role in JUnit testing by providing a way to execute specific code before and after each test method.

Here's how each annotation functions in JUnit testing:

• @Before: This annotation is used to mark a method that should run before each test method within a test class. It is typically utilized for setting up the necessary preconditions or initializing resources required for the test.
• @After: Conversely, the @After annotation is placed on a method that should execute after each test method. It is commonly employed for cleaning up resources, closing connections, or performing any necessary post-test actions.

By using these annotations, developers can ensure that the environment for each test is properly set up and cleaned up, promoting consistency and reliability in the testing process.
