TestPackage provides a clean way to package your functional tests and run them as a jar file with sharding and package level run options. All that we need to do is created a maven/gradle subproject for functional tests and have the testpackage’s dependency and manifest file entry to get an executable jar package.

Once the jar is created all we need to do is run ‘java -jar the-test-package.jar package.that.contain.tests’. This helps a lot in continuous delivery where the functional test artifact can be created at the build stage and promoted to run at the functional test stage without having to access the source code and rebuild later.
