public interface MethodRule

A MethodRule is an alteration in how a test method is run and reported. Multiple MethodRules can be applied to a test method. The Statement that executes the method is passed to each annotated Rule in turn, and each may return a substitute or modified Statement, which is passed to the next Rule, if any. For examples of how this can be useful, see these provided MethodRules, or write your own:
