I'm new to EMMA, I don't know how to use this for android system. Can anyone please give a sample for using this with android. Thanks a lot.

I've only been able to get emma working using ant. If you've got an ant build set up then you can run:
ant emma debug install ant emma debug install test The first is run in your project directory, the second from your test directory. See the docs for more details: http://developer.android.com/guide/developing/building/building-cmdline.html
If you don't have an ant build.xml file already you can see how to generate one from your current project here: http://developer.android.com/guide/developing/projects/projects-cmdline.html
The sad part is this will only work on the emulator or a rooted device. This is because the coverage file gets generated in a folder that requires root. I also needed to modify the android-sdk/tools/ant/build.xml file to copy the file on my rooted device elsewhere so I could pull it off. I modified the emma block of the xml to be the following:
<if condition="${emma.enabled}"> <then> <echo>WARNING: Code Coverage is currently only supported on the emulator and rooted devices.</echo> <run-tests-helper emma.enabled="true"> <extra-instrument-args> <arg value="-e" /> <arg value="coverageFile" /> <arg value="${emma.dump.file}" /> </extra-instrument-args> </run-tests-helper> <echo>Copying coverage to readable directory...</echo> <exec executable="${adb}" failonerror="true"> <arg line="${adb.device.arg}" /> <arg value="shell" /> <arg value="echo cp ${emma.dump.file} /sdcard/coverage.ec | su" /> </exec> <echo>Downloading coverage file into project directory...</echo> <exec executable="${adb}" failonerror="true"> <arg line="${adb.device.arg}" /> <arg value="pull" /> <arg value="/sdcard/coverage.ec" /> <arg value="coverage.ec" /> </exec> <echo>Extracting coverage report...</echo> <emma> <report sourcepath="${tested.project.absolute.dir}/${source.dir}" verbosity="${verbosity}"> <!-- TODO: report.dir or something like should be introduced if necessary --> <infileset dir="."> <include name="coverage.ec" /> <include name="coverage.em" /> </infileset> <!-- TODO: reports in other, indicated by user formats --> <html outfile="coverage.html" /> </report> </emma> <echo>Cleaning up temporary files...</echo> <delete file="coverage.ec" /> <delete file="coverage.em" /> <echo>Saving the report file in ${basedir}/coverage/coverage.html</echo> </then> <else> <run-tests-helper /> </else> </if> If you love us?
