I made a vscode language server a while back but didn’t have a great way of doing CI tests on it (to prove the artifact itself works). I recently figured out one way to do this that’s pretty convenient. I used code-server with selenium webdriver.

Once you’ve confirmed that the http port is responding, you can write selenium webdriver tests against it, rendered as a fairly empty canvas here:
