"Starting Jest in Watch mode failed too many times" helper is not very helpful

Environment

1. node -v: 12.9.1

2. yarn -v: 1.21.1

3. npm ls jest or npm ls react-scripts (if you haven’t ejected): react-scripts@3.3.0

4. your vscode-jest settings if customized:

   • jest.pathToJest? yarn test

5. Operating system: macOS 10.15.2

Prerequisite

• are you able to run jest test from command line? yes
• how do you run your tests from command line? (for example: npm run test or node_modules/.bin/jest) yarn test

Steps to Reproduce

• create a workspace with multiple folders
• add a folder (folder-1) without any test, in package.json add a test script with --passWithNoTests, vscode-jest will still consider jest failed.
• add another folder (folder-2) without any test, in package.json, add a test script with "test": echo "no test yet"

Relevant Debug Info

from folder-1 output channel:

Done in 0.93s.

Starting Jest in Watch mode failed too many times and has been stopped.
Consider add this workspace folder to disabledWorkspaceFolders

from folder-2 output channel:

yarn run v1.21.1

$ echo 'test not yet implemented' --testLocationInResults --json --useStderr --outputFile /var/folders/vg/yw9mltwd1mj_29xbvhwywc980000gn/T/jest_runner_core.json --watch --no-coverage --no-color --reporters default --reporters /Users/xxx/.vscode/extensions/orta.vscode-jest-3.1.0/out/reporter.js

test not yet implemented --testLocationInResults --json --useStderr --outputFile /var/folders/vg/yw9mltwd1mj_29xbvhwywc980000gn/T/jest_runner_core.json --watch --no-coverage --no-color --reporters default --reporters /Users/xxx/.vscode/extensions/orta.vscode-jest-3.1.0/out/reporter.js

Expected Behavior

• folder-1 output channel has wiped out the actual command executed
• it should not report jest test failure
• if it must, at least show which folder is failed in the helper popup
• our troubleshooting section should be revamped to provide better self-help instructions…

Actual Behavior

right now all failures in a workspace env suggest users to “disableWorkspaceFolders”, which is not always helpful

you could also, as a work around, modify pathToJest to source which version of node first

// in your workspace setting
"jest.pathToJest": "PATH=/Path/to/your/Node/bin/:$PATH yarn test"

I had the same issue, and my problem ended up being that I was using nvm, so the plugin couldn’t find node.

My solution ended up being installing node using one of the recommended installers.
