Eclipse, Android and EMMA code coverage

On of the examples I'm including in the tutorial I will be presenting at LinuxCon North America 2011 (link to presentation) is a step by step use of EMMA code coverage from Eclipse to help you navigate through the Android application source code while applying Test Driven Development techniques.


This screenshot, taken from the tutorial examples, shows:

  1. The code coverage results directly summarized and highlighted in the Activity source code inside Eclipse editor
  2. The coverage view lists coverage summaries for the Android project, allowing drill-down to method level
If you are seriously developing Android applications you shouldn't miss this tutorial.
Hope to see you there.

I regulary use Emma för unit testing and it rocks. However, sometimes, i would like to launch the app än freeride test it för a while and then see what code paths i have touched. How do I do that without writing a dummy testcase?

I hope http://dtmilano.blogspot.com/2011/11/obtaining-code-coverage-of-running.html helps you find the answer to your question.

Android is a mobile operating system that has been highly successful because of its incredible features. Most of the smart phones in the market run on Android OS. Since the success of Android, lot of Android Development Companies has spurred up everywhere. We are also putting good logic to develop more in this field.Android app developers

Hi,

When I run the ant in order to get the .ec for an Android Test Project, after that when I tried to import the .ec into the eclipse, I get the message "class X appears to be instrumented already" and the class is related to the Android Project (not Android Project Test).

Has someone any idea?

Thanks.
Best regards.

For future reference, the code coverage slides start at slide 145.

Looked at the slides and still don't understand how to enable Eclipse and Android for Emma. Can you make a separate presentation on how to enable it for us newbs?
