类 ApplicationEventsHolder

java.lang.Object
cn.taketoday.test.context.event.ApplicationEventsHolder
public abstract class ApplicationEventsHolder extends Object
Holder class to expose the application events published during the execution of a test in the form of a thread-bound ApplicationEvents object.

ApplicationEvents are registered in this holder and managed by the ApplicationEventsTestExecutionListener.

Although this class is public, it is only intended for use within the TestContext Framework or in the implementation of third-party extensions. Test authors should therefore allow the current instance of ApplicationEvents to be @Autowired into a field in the test class or injected via a parameter in test and lifecycle methods when using JUnit Jupiter and the ApplicationExtension.
