title: Regarding instrumentation test cases for APK
body: <p>I have developed an Android application that parses RSS feed from a website. </p>
  
  <p>I have developed instrumentation test cases for application since I have access to code. So far everything is ok. </p>
  
  <p>Now I want to ask is there any way or is it possible through which I can develop instrument test cases for apk when I don't have access to code. </p>
  
  <p>If yes then what are all components in Android that can be tested through.</p>
  
  <p>Thanks in advance </p>
