Examples of org.junit.rules.MethodRule

org.junit.rules.MethodRule
A MethodRule is an alteration in how a test method is run and reported. Multiple {@link MethodRule}s can be applied to a test method. The {@link Statement} that executes the method is passed to each annotated{@link Rule} in turn, and each may return a substitute or modified{@link Statement}, which is passed to the next {@link Rule}, if any. For examples of how this can be useful, see these provided MethodRules, or write your own:
- {@link ErrorCollector}: collect multiple errors in one test method
- {@link ExpectedException}: make flexible assertions about thrown exceptions
- {@link ExternalResource}: start and stop a server, for example
- {@link TemporaryFolder}: create fresh files, and delete after test
- {@link TestName}: remember the test name for use during the method
- {@link TestWatchman}: add logic at events during method execution
- {@link Timeout}: cause test to fail after a set time
- {@link Verifier}: fail test if object state ends up incorrect
Note that {@link MethodRule} has been replaced by {@link TestRule}, which has the added benefit of supporting class rules. @since 4.7
