ListenersAdded to specBefore and after spec, feature, iterationOn errorSkipped spec or featureListen passively, do not throw exceptionsGet passed oﬃcial test results 29

InterceptorsAdded to spec, feature or ﬁxture methodsIntercept method invocationinvocation.proceed()Can change test outcome and behaviorCan throw exceptionsBut .. following interceptors can do the same 30

Interceptors eAdded to spec, feature or ﬁxture methods m iIntercept method invocation T @invocation.proceed()Can change test outcome and behaviorCan throw exceptionsBut .. following interceptors can do the same 31

GotchasUse the right tool for the jobAttach interceptors only where they belongDo not throw exceptions from listenersReuse listeners or interceptors with cautionMark feature methods as skipped if neededSkipped (skip a few) vs. excluded (run a few) 32
