JaCoCo

Provides support for JaCoCo Code Coverage in combination with Java containers.

• Allows for recording and extraction of code coverage files from containers
• Support for Testcontainers API

NOTE: Using this is a bit complex as it also requires some changes to the java application in the container.
Please have a look at the advanced-demo and the corresponding GitHub Actions workflow for details.
