title: Unit Test Cases with JUnit +(Robolectric or Mockito or both in Android)
body: <p>This is first time I have to write unit test cases in Android.</p>
  
  <p>So I have searched lots of things.</p>
  
  <ol>
  <li><strong>Robolectric framewordk</strong> - Runs on JVM</li>
  <li><strong>Mockito Framwork</strong> - Mocking objects</li>
  </ol>
  
  <p>So I have some doubts in Robolectric &amp; Mokito.</p>
  
  <ol>
  <li>Should I have to use Robolectric only with JUnit in Android app?</li>
  <li>Should I have to use Mockito only with JUnit in Android app?</li>
  <li>Should I have to go with both framework?</li>
  <li>What is the difference between Mockito &amp; Robolectric?</li>
  </ol>
  
  <p>I have search for difference between Mokito &amp; Robolectric but don't get any proper answer for that.</p>
  
  <p>Please suggest.</p>
