Class JUnitTestRunner

java.lang.Object

org.apache.tools.ant.taskdefs.optional.junit.JUnitTestRunner

All Implemented Interfaces:

junit.framework.TestListener, JUnitTaskMirror.JUnitTestRunnerMirror

public class JUnitTestRunner
extends java.lang.Object
implements junit.framework.TestListener, JUnitTaskMirror.JUnitTestRunnerMirror

Simple Testrunner for JUnit that runs all tests of a testsuite.

This TestRunner expects a name of a TestCase class as its argument. If this class provides a static suite() method it will be called and the resulting Test will be run. So, the signature should be

     public static junit.framework.Test suite()
 

If no such method exists, all public methods starting with "test" and taking no argument will be run.

Summary output is generated at the end.
