This is an xsl template that is used to convert the xml test output from Unity tests to a format Jenkins can read.
This is extremely useful for test driven development in C using ceedling/unity.
For use in ceedling, edit your project.yml.in file and enable the xml_tests_report plugin. Now when you run unit tests you will get some xml output in build/artifacts/test/report.xml.
To get Jenkins working, you'll need the xUnit plugin. In the dropdown, select "Custom tool." The pattern is build/artifacts/test/report.xml. The custom stylesheet is the unity.xsl found in this repo.
This is not my own work; I found this somewhere on the internet. I am simply posting this here on github so that others trying to get Unity C unit tests running on Jenkins won't have as much hassle as I did.
To the original author: thank you.
