Stuck at "Starting watch mode"

[dominik-fielmann]

I have been stuck with this problem since I switched to a new laptop with Ubuntu 20.04.

The issue is the exact same one as mentioned here. vscode-jest is stuck in the "starting watch mode" phase and never displays the results of the tests.

A colleague who has a similar setup as me has the exact same problem. VSCode is installed via snap, in case that's relevant.

Environment

1. node -v: v14.13.1

2. npm -v: 6.14.8

3. npm ls jest or npm ls react-scripts (if you haven’t ejected): [email protected]

4. your vscode-jest settings if customized:

   • jest.pathToJest? not changed, but I tried as well with "npm run test --"
   • jest.pathToConfig? not changed
   • anything else that you think might be relevant? I disabled all other extensions.

5. Operating system: Ubuntu 20.04

Prerequisite

• are you able to run jest test from command line? yes
• how do you run your tests from command line? npm run test

Steps to Reproduce

Happens with any jest repository unfortunately.

Relevant Debug Info

Complete output from the extension ouput window:

Finished running all tests. Starting watch mode.

Expected Behavior

The tests are run and the UI shows the result next to the test.

Actual Behavior

Jest: Starting watch mode keeps showing indefinitely. The test indicator status remains an empty circle.

Because of a suspicion, I removed the code snap package and reinstalled it via apt. Suddenly it works. So this bug seems to happen with the snap version of VS Code only.

close as it didn't seem to be related to this extension.
