Interface ApplicationEvents

public interface ApplicationEvents
ApplicationEvents encapsulates all application events that were fired during the execution of a single test method.

To use ApplicationEvents in your tests, do the following.

  • Ensure that your test class is annotated or meta-annotated with @RecordApplicationEvents.
  • Ensure that the ApplicationEventsTestExecutionListener is registered. Note, however, that it is registered by default and only needs to be manually registered if you have custom configuration via @TestExecutionListeners that does not include the default listeners.
  • Annotate a field of type ApplicationEvents with @Autowired and use that instance of ApplicationEvents in your test and lifecycle methods.
  • With JUnit Jupiter, you may optionally declare a parameter of type ApplicationEvents in a test or lifecycle method as an alternative to an @Autowired field in the test class.
