public interface MethodRule
A MethodRule is an alteration in how a test method is run and reported. MultipleMethodRules can be applied to a test method. TheStatementthat executes the method is passed to each annotatedRulein turn, and each may return a substitute or modifiedStatement, which is passed to the nextRule, if any. For an example of how this can be useful, seeTestWatchman.Note that
MethodRulehas been replaced byTestRule, which has the added benefit of supporting class rules.- Since:
