Interface ExpectFailure.StandardSubjectBuilderCallback

Enclosing class:
ExpectFailure

public static interface ExpectFailure.StandardSubjectBuilderCallback
A "functional interface" for expectFailure() to invoke and capture failures.

Java 8+ users should pass a lambda to .expectFailure() rather than directly implement this interface. Java 7+ users can define an @Rule ExpectFailure instance instead, however if you prefer the .expectFailure() pattern you can use this interface to pass in an anonymous class.
