NOTE:

NOTE: Of late, I have been getting requests for very trivial problems that many of you are facing in your day-to-day work. This blog is not to solve your "project" problems - surely not a "Support" site.
I just love to share my knowledge in my spare time and would appreciate any questions or feedback on the articles and code I have shared. I also do appreciate thought-provoking questions that would lead me to write more articles and share.
But please do not put your day-to-day trivial problems here. Even if you do, you most probably would not get a response here.
Thanks

Android - Code Coverage - Unit Testing

This is a very small post for all those who have been strugling to generate the Android Test Coverage Using the ant scripts give by android sdk itself.


I am assuming that you have created one project containing the actual source code to be tested - assume it is called "MyProject" and you have created another test project that tests MyProject, that is named MyProjectTest.


Then, you have written jUnit tests using the inherent testing support framework with android. Now, you have run your unit tests and they run successfully in ecplise. You then, what to check on the code coverage of these unit tests. Here are the steps for the same:



  •    At the command prompt, change directory to the MyProject folder
  •    Rename the existing build.xml to build_orig.xml
  •    Run this command:
android update project -p . (including the last dot)
  •    Then change directory to cd ..\MyProjectTest
  •    Rename the existing build.xml to build_orig.xml
  •    Run this command:
android update test-project -m D:/..../source/MyProject -p .  (including the last dot and where you give your complete path to the MyProject folder after -m)
  •    Then, run the  command -
ant emma debug install test
This should generate a html report of the coverage under MyProjectTest/coverage


Troubleshooting:

  •    Incase you get an error "remote object coverage.ec does not exist" then start adb shell in another command prompt - in order to give write permissions to the sdcard for writing the coverage.ec file
  •    Then, run the following command at the shell
mount -o remount rw /sdcard
  •    Then you should be able to generate the report.

I would learn more of android programming in the future from your blogs but before that I want to ask you, have you ever worked on getting android app to connect with AWS, Google app engine or any open source remote database in cloud? if so please share the link so that I can learn from it and start the app development with cloud connect.

  21. The themes here are amazing. I would like to see an easier way to search with more relevant results. i.e. when I search autumn, I really don't want to find Assassins Creed or Warrior girl...just a pretty autumn seasonal theme for my background.

  26. Good post.
    For people starting the 'testing' now, I would also recommend trying out 'TestNG'. It is better than JUnit for Integration/ Module testing.
