CI/CD for vscode extension

[Hemavathy12]

I'm planning to use wdio-vscode-service for implementing end-to-end tests for a vscode extension. I need to run those tests as part of CI/CD using Docker + Kuberbetes. I could see some docker documentation for running tests written for browser services but couldn't find any for vscode service. Need some help for the same.

I tried using node:18.19.1-bullseye docker image and I got the following error:

RequestError: connect ECONNREFUSED 0.0.0.0:38755

I am not sure how your setup looks like but this error says that WebdriverIO can't connect to Chromedriver. The Chromedriver logs reveal the following error:

error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory

I am not sure what this error means but it seems there are some missing dependency in the Docker image.

I ran the tests using this docker image: https://github.com/nodejs/docker-node/blob/619b871fb3d89dc6d6333914b46bf526e781eec5/18/bullseye/Dockerfile

Assumed that pre-requisite for running the tests written for a vscode extension is NodeJs - v16.x or higher. Do we need any other requirements?

I don't think so.
