/**
* Surefire provider for Teamscale's impacted test engine.
*
* This package contains a copy of the {@link JUnitPlatformProvider} (and other required classes) from
* https://github.com/apache/maven-surefire/tree/surefire-3.0.0-M5/surefire-providers/surefire-junit-platform. This
* subclass disables all other test engines except our own.
*
* Ideally, we would like to subclass the original {@link JUnitPlatformProvider} and only override what we want to
* change, but it is not published as an artifact by Surefire and all the stuff we want to modify is private. So we
* copied the {@link JUnitPlatformProvider} class and made the necessary extension point protected ({@link
* #newFilters()}).
*
* Starting with Maven 3.0.0-M6, users can also configure the included engines in Surefire directly via {@code
* includeJUnit5Engines}. However, that has not yet been released.
*
* Copyright notices in the files in this project must be retained, as the files are copies from the Maven Surefire
* repository.
