public class JUnit4TestMethodAdapter extends Object implements junit.framework.Test
Adapter between JUnit 3.8.x API and JUnit 4.x API for execution of tests and listening of events (test start, test finish, test failure, test skipped). The constructor is passed a JUnit 4 test class and a list of name of methods in it that should be executed.
