Hello,
first, thanks to my friend @Kott for showing me this program.
pluginval (https://github.com/Tracktion/pluginval) is a plugin tester for AU, VST and VST3 plugins. It is actively developed by the Tracktion team. It automates many things which are usually done when testing plugins and so could be useful in CI (Continuous Integration) especially for distros and repositories.
It runs on the JUCE so in theory, LV2 support could be added. Right now, a LV2-based alternative is lv2lint (https://github.com/OpenMusicKontrollers/lv2lint) although the focus is slightly different.
