Compoud code coverage results

[Andrew Hewitt]

Hi there, Just started using this tool and really finding it useful. I wanted to ask whether the tool, could be made capable of compounding coverage results. I have a set of java packages and multiple programs in those packages, but nothing uses all the packages at once and some programs have modes of operation, which only use half of the functionality.

Regards

Andy

Hi Andy,

this absolutely possible. Coverage analysis with JaCoCo is a two step process:

1) Execute some Java program and collect execution data (*.exec files)

2) Generate a coverage report from execution data (one or multiple *.exec files)

This means you can run any number of Java processes before you create a test report. In addition there is a “merge” function to consolidate multiple *.exec files in a single one.

Regards,
