Android test code coverage, Eclipse

Question

Is there a way to run unit tests for Android from Eclipse in a way that will instrument the code and measure test code coverage?

I\'m looking for a simple way to fi

Disclaimer: I'm an Atlassian

The Atlassian Clover tool has also support for Android - it measures coverage for both application code and unit tests. Although in alpha stage, it works quite well - it works with Eclipse version 3.6.2 and higher.

If you want to find areas of your application which require improvement, then the following Clover features will be perfect for this task:

• Clover Dashboard
• Coverage Cloud Report
• Coverage TreeMap Report
• Coverage Explorer

Oh, and the Clover HTML Report looks fantastic!

I've been used EMMA (android already support it) for code coverage (and android-junit-report for test reports), here is a summary:

• Create android project (or library)

android.bat update project -p project -n my_project -t android-16

cd project

ant emma clean debug

• create a test project (linked to previous library)

android.bat update project --library ..\project -p project_Test -n project_Test -t

• in case the main project is not a library

android.bat update project -m ..\project -p project_Test -n project_Test -t

ant emma clean debug install I ddidn't use 'test' since I want to run my own instrument

adb shell am instrument -e coverage true -e coverageFile sdcard/coverage.ec -w com..myproject.test/com.zutubi.android.junitreport.JUnitReportTestRunner

• Pull files from device (emulator)

adb pull sdcard/junit-report.xml

adb pull sdcard/coverage.ec

• Generate XML report (can also generate html report)

java -cp emma.jar emma report -r xml -in bin/coverage.em,coverage.ec

• Generate HTML report (can also generate html report)

java -cp emma.jar emma report -r html -in bin/coverage.em,coverage.ec

• Using Post-builds (Jenkins):

  • JUnit report XML
  • Emma Coverage report (give the coverage.xml as input)

Don't need the emma.jar into libs

Install EclEmma from Eclipse Marketplace.

If you have <path to test project>/build.xml file rename it.

I was able to generate test coverage report by executing following from the console:

<path to android tools>android update test-project -m <path to app project> -p <path to test project> + Enter,

cd <path to test project> + Enter,

ant emma debug install test + Enter,

where <path to android tools> is /opt/android-sdk-linux/tools/ on my machine - the folder where android SDK is installed.

This generated <path to test project>/bin/coverage.html file.

If you get "wrong JAVA_HOME" error execute gksu gedit /etc/environment + Enter, correct JAVA_HOME, save the file, log out or reboot and try again.
