title: Extend TestNG suite file to other suite files
body: <p>I was not able to find the solution I was looking for but here it goes:
  I need to always perform a step before my test cases (lets say a login step, for each and every single of my tests). I created a class which deals with this, but has @Parameters associated (username + password) -- lets call it <strong>LoginSetupTest</strong></p>
  <p>Now, I created a <strong>PageTest</strong>, which will extend <strong>LoginSetupTest</strong>, and will be ran through <em>PageTestSuite.xml</em>. That would be fine for one test, but as we need to create more, is there any way we can create like a parent suite, which will then be extended by other suite files?</p>
  <p>Also, do you think that this is the best approach to deal with such a situation?
  Thanks!</p>
