Mastering the Essentials of Spring Boot Testing

🧪 Today, let's dive into the essentials of testing in Spring Boot! Whether you’re building REST APIs or simple web applications, testing is crucial to ensure reliability.

Here's a breakdown of the key concepts I find valuable:

1. Types of Tests:
- Unit Tests: Focus on individual components.
- Integration Tests: Check the interaction between components.
- End-to-End Tests: Validate the whole system’s functionality.

2. Annotations You Should Know:
- @SpringBootTest: Used for loading the application context.
- @WebMvcTest: Focused on testing controllers only.
- @MockBean: To create mock objects in your tests.

3. Basic Example:

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

    @Autowired
    private MyService myService;

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

📅 Remember, writing tests early helps identify issues sooner, saving time and effort in the long run. Happy coding! 🚀
