I use vscode-test to test my VSCode extension. But recently it directly throws Fail when initializing. The error is throw from here https://github.com/microsoft/vscode-test/blob/master/lib/runTest.ts#L134, but I don’t know why it throw. I can pass the test on my Macbook Pro(masOS 10.14.6, nodejs v10.16.0). I can’t  reproduce it on my own computer no matter how. 🤦‍♂️

Please help me or give a hint where I might missed or wrong. Thank you very much. 🙏t2:

Oh, I can reproduce it now.  VSCode on my computer has installed the extension(online version). It seems like covered the error from the unpacked extension. It should be a bug of my code 😅.

Glad you solved it. Just a quick note, though: if you test under linux, you need to configure Xvfb and start it. With ubuntu-16.04, it’s pretty easy. You just need a step like so:

- name: Start Xvfb
      run: |
        set -e
        /usr/bin/Xvfb :10 -ac >> /tmp/Xvfb.out 2>&1 &
        disown -ar
      if: runner.os == 'Linux'

For ubuntu-18.04 / ubuntu-latest, see vscode’s own tests: https://github.com/microsoft/vscode/blob/df448dd078d60103a05fa8f068318abe443347d3/.github/workflows/ci.yml#L128-L135
