Java 单元测试测试异常

在单元测试中总会涉及到Exception的测试，测试的范例如下：

public void testGetUserNotDefined(){
  TestRequest req = new TestRequest("test not Defined");
  try{  
      contr.getUser(request);
      fail("An exception should be raised if the request handler has not been defined");
  }catch (Runtimeexception exception){   
    assertTrue(true);
 }
}
