title: Test suite issue in robotium
body: <p>I have one test case file with around 20 methods (test cases) which extends ActivityInstrumentationTestCase2. I need to write a suite which will call only selected test case methods, I know in junit there is one method which accepts the methods to be executed</p>
  
  <pre><code>    suite.addTest( new AllTestCases("testcase1"));
  </code></pre>
  
  <p>Is there a similar way to do stuff in android robotium? If yes, please help me out with a way to fix this. Thanks.</p>
