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:
To view this in IntelliJ Idea, from the menu bar, select Run > Show Code Coverage Data. In the new window (Choose Coverage Suite to Display), press the + button and select your .exec file. The test coverage results will appear in the editor Coverage tab.
To generate the Coverage Report files for the above .exec file, select Run > Generate Coverage Report. Then select your output directory and click on Save. Your reports would be generated to the selected folder. Open the index.html file in the folder to view the results on the browser. I am using IntelliJ IDEA 2019.3.4 (Community Edition)
