The TestDriver provides many methods that can be overridden to change the default configuration. These are as follows:

  /** 
   * How long to wait for test results to be returned from the client(s). If goes longer than the 
   * specified limit, will throw an exception and kill the running test cases. Default value is * RESULTS_TIMEOUT. 
   * @return 
   */ 
   protected long getResultsTimeout() 
   { 
      return RESULTS_TIMEOUT; 
   } 

  /** 
   * How long for the server test case to wait for tear down message. If exceeds timeout, 
   * will throw exception. The default value is TEARDOWN_TIMEOUT. 
   * @return 
   */ 
   protected long getTearDownTimeout() 
   { 
       return TEARDOWN_TIMEOUT; 
   }
 
   /** 
    * How long to allow each of the test cases to run their tests. If exceeds this timeout 
    * will throw exception and kill tests. The default value is RUN_TEST_TIMEOUT. 
    * @return 
    */ 
    protected long getRunTestTimeout() 
    { 
       return RUN_TEST_TIMEOUT; 
    } 

   /** 
    * Returns the classpath to be added to the classpath used to start the client tests. 
    * Default return is null, which means no extra classpath will be added. 
    * @return 
    */ 
    protected String getExtendedClientClasspath() 
    { 
       return null; 
    } 

   /** 
    * Returns the classpath to be added to the classpath used to start the client tests. 
    * Default return is null, which means no extra classpath will be added. 
    * @return 
    */ 
    protected String getExtendedServerClasspath() 
    { 
       return null; 
    } 

   /** 
    * Returns the VM arguments to be passed to the vm when creating the client test cases (actually their harness). 
    * The default value is null. 
    * @return 
    */ 
    protected String getClientJVMArguments() 
    { 
        return null; 
    } 

   /**

Gotchas

If see something weird like:

junit.framework.AssertionFailedError: Method "Yourclass.class" not found

check to make sure you do not have a constructor in your test class that looks like:

public Yourclass(String name) { super(NAME); // where NAME = "Yourclass.class" }
