Interface MethodRule

All Known Implementing Classes:

TestWatchman

Deprecated.

@Deprecated
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:

• ErrorCollector: collect multiple errors in one test method
• ExpectedException: make flexible assertions about thrown exceptions
• ExternalResource: start and stop a server, for example
• TemporaryFolder: create fresh files, and delete after test
• TestName: remember the test name for use during the method
• TestWatchman: add logic at events during method execution
• Timeout: cause test to fail after a set time
• Verifier: fail test if object state ends up incorrect
