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 `MethodRule`s 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

Method Summary
