Using Configuration in Tests

The following snippets loads the application context with the configuration given in TestConfiguration.class

@SpringBootTest(classes = TestConfiguration.class)
public class TestWithContext {

}

Override Configuration in Tests

With the following snippet you can include the configuration from BasicConfiguration and then override it in TestConfiguration

@RunWith(SpringRunner.class)
@SpringBootTest(classes = TestWithContext.TestConfiguration.class)
public class TestWithContext {

    @Configuration
    @Import(BasicConfiguration.class)
    public static class TestConfiguration {

        @Bean
        ...

    }
    
}

Enable Component Scan in Tests

If you want to use classes annotated with @Component in your tests, you can use the @ComponentScan(basePackages = "...") annotation:

public class MyTest {
    
    // ...

    @Configuration
    @ComponentScan(basePackages = "ch.lihsmi.spring.amqp.byexample.exchanges.direct")
    public static class TestConfiguration {

        // ...

    }

    @Component
    public static class TestMessageListener {

        // ...

    }
    
}
