how to use jacoco.exec report

Question

I generated a code coverage report from jacoco, which is jacoco.exec. But I don't know how to use it ...

The way I generated it is through command line:

java -javaagent:/path/to/jacocoagent.jar=include=some.package.*,output=file org.junit.runner.JUnitCore some.package.ClassTest 

Then I got the jacoco.exec report. All I need is just the number of percentage, and I am using command line only. Is there a way to convert this report to a readable txt file?

Thanks all

Answer 1

In IntelliJ Idea from the menu select Analyze > Show Coverage data. In the new window press the + button and select your .exec file. The test coverage results will appear in the editor Coverage tab.

Update:

In the latest version of Intellij Idea the menu has been moved to Run > Show Code Coverage Data

For Eclipse users, you can simply use EclEmma jacoco plugin in Eclipse. Window > Show View > Coverage (of course you must install the plugin first). In the Coverage window, Right click > Import >..... Select the exec file (or other nice methods), select your source code, then see. You can also export the result to html file.
