I suggest to decorate ApplicationContextAssert::getBean(s) methods with a @CheckReturnValue annotation so that incomplete statements like the following are spotted by static analysis tools like SpotBugs and IntelliJ IDEA:

assertThat(context).getBean(MyService.class);

To achieve this, no additional dependency is needed and Spring Boot Test can declare its own @CheckReturnValue annotation, similarly to what AssertJ and Mockito do.

I can raise a PR with the changes if the idea is accepted.
