How can I use JUnit with the Spring Testing Framework?

You can use JUnit to write tests for your Spring applications by leveraging the Spring TestContext Framework. This allows you to load the application context and test your beans.

Can you show me a simple example of a JUnit test in a Spring application?

Sure! Here's a basic example:

@RunWith(SpringRunner.class)
@SpringBootTest
public class MyServiceTest {

    @Autowired
    private MyService myService;

    @Test
    public void testServiceMethod() {
        assertEquals("Expected Result", myService.serviceMethod());
    }
}

What annotations do I need to use for testing with JUnit in Spring?

You typically use @RunWith(SpringRunner.class) to integrate Spring Test with JUnit, and @SpringBootTest to load the application context.

Are there any best practices for writing tests in Spring?

Yes, some best practices include keeping tests isolated, using mocks for dependencies, and ensuring tests are repeatable and fast.
