HelloService.class is not in the classpath.

A HelloService bean will be created from the helloService() method only when there is no other

HelloService bean in the ApplicationContext.

This auto-configuration class is used only when the HelloService.class is not on the classpath.

This auto-configuration class is used only when the HelloService.class is on the classpath.

@ActiveProfiles is a class-level annotation that is used to instruct the Spring TestContext Framework to record all application events that are published in the ApplicationContext during the execution of a single test.

@ActiveProfiles is a class-level annotation that you can use to configure how the Spring TestContext Framework is bootstrapped.

@ActiveProfiles is a class-level annotation that you can use to configure the locations of properties files and inlined properties to be added to the set of PropertySources in the Environment for an ApplicationContext loaded for an integration test.
