What is the Spring Testing Framework for unit tests?

The Spring Testing Framework provides support for testing Spring components with JUnit or TestNG, making unit tests easier.

How do I set up a unit test using the Spring Testing Framework?

To set up a unit test, you need to annotate your test class with @RunWith(SpringJUnit4ClassRunner.class) and use @ContextConfiguration to specify the configuration.

Can you give me an example of a simple unit test?

Sure! Here's a simple example:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {AppConfig.class})
public class MyServiceTest {

    @Autowired
    private MyService myService;

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

What are some best practices for writing unit tests in Spring?

Some best practices include keeping tests isolated, using mocks for dependencies, and following the Arrange-Act-Assert pattern.
