How do I set up and tear down tests in JUnit?

How do I set up and tear down tests in JUnit?

In JUnit, you can use the @Before and @After annotations for setup and teardown methods. @Before runs before each test, and @After runs after each test.

Can you give me an example of using @Before and @After?

Sure! Here's a simple example:

@Before
public void setUp() {
    // Code to set up test environment
}

@After
public void tearDown() {
    // Code to clean up after tests
}

What if I want to set up and tear down once for all tests?

You can use @BeforeClass and @AfterClass annotations for that. These methods run once before and after all tests in the class.

Is there a way to handle exceptions in setup or teardown?

Yes, you can catch exceptions in your setup or teardown methods and handle them accordingly, but be cautious as it may affect test results.
