Spring Boot FAQ: Top Questions

Spring Boot supports unit, integration, and slice testing using Spring Boot Test and JUnit.

🗺️ Step-by-Step:

1. Add spring-boot-starter-test dependency.
2. Write tests using annotations like @SpringBootTest, @WebMvcTest, or @DataJpaTest.
3. Run tests via Maven/Gradle or IDE.

📥 Example:

@SpringBootTest
public class MyAppTests {
  @Test
  public void contextLoads() {
    assertTrue(true);
  }
}

🏆 Expected Output:

Application context loads successfully and tests pass.

🛠️ Use Cases:

• Ensure application starts correctly.
• Test API endpoints and data layers independently.
• Maintain high test coverage in CI/CD pipelines.
