Spring Framework Testing Concepts

Process: https://spring.io/blog/2016/04/15/testing-improvements-in-spring-boot-1-4

Use:

dependencies {
    testImplementation('org.springframework.boot:spring-boot-starter-test')
}

This started dependency pulls everything that is needed to write JUnit tests.

@SpringBootTest - this is required, otherwise beans won't get injected in our tests.

@WebMvcTest

@RunWith(SpringRunner.class)

@IntegrationTest, @WebIntegrationTest

SpringBoot Test Example

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

    @Autowired
    private SomeComponent someComponentWeWantToTest;

    // ...

}

Testing Logging Configuration

By default, test logging is executed by Logback.
