Annotation Type FailsWith

@Retention(value=RUNTIME)
@Target(value={METHOD,TYPE})
public @interface FailsWith

Indicates that a feature method is expected to fail with the given exception. Useful for pinpointing bugs until they get fixed, or as a replacement for exception conditions in certain corner cases where they cannot be used (like specifying the behavior of exception conditions). In all other cases, exception conditions are preferable.

Applying this annotation to a specification has the same effect as applying it to all feature methods that aren't already annotated with @FailsWith.
