Yes, WebVTT is part of the Web Platform tests:
https://github.com/w3c/web-platform-tests/tree/master/webvtt

The results can be inspected here: https://wpt.fyi/webvtt.
All browsers have issues.

Funnily, the browser that supports the least of the more interesting
features is the most green in rendering:

Kind Regards,
Silvia.
