title: Testing android apps with TDD vs Debugger
body: <p>I would like to ask something interesting. When I am developing native android apps,and want to make sure that there no null objects,I use the debugger as shown.</p>

  <p>So I put a break point in the line I want,I step over my code and the fun begins:). However,there is this TDD,which I have never used. Are they any specific tools for that? Is it more efficient?</p>
  
  <p>Regards,</p>
