Karma server not stopped when vscode is closed about karma-test-explorer

[lucono]

@doktordirk I was later able to reproduce this. Try out the visx from the beta branch to confirm if it resolves the issue.

tx. Issue solved!

Released in v0.6.0

@doktordirk if you run the command ps -fe, what's the full process command printed for the unterminated node processes?

[doktordirk]

@lucono nothing exiting i'd guess

@doktordirk I'm not able to reproduce this (on ubuntu 18.04). The Karma Test Explorer and Karma Server output channel debug logs may have some information on why it might be failing to stop. If you'd like to look into it locally, the point where the server is stopped is here, which leads here further down the line, with the Karma server then killed here.
