Which terms did you search for in User Guide?

Jest Debugging

Environment

1. node -v: 8.5
2. npm -v: 5.4
3. yarn --version (if you use Yarn):
4. npm ls react-scripts (if you haven’t ejected): 1.0.14

Then, specify:

1. Operating system: windows 8
2. Browser and version (if relevant):

Steps to Reproduce

Here's repro branch

https://github.com/TheTFo/cria/tree/jest-debug?files=1

Attempt to debug tests from vscode launcher, placing a break point on the line indicated in comment in this file:

https://github.com/TheTFo/cria/blob/jest-debug/src/actions/todoActions.js

Breakpoints don't appear to hit the appropriate lines. Not sure what's causing it. I don't see transpiled code, just wierd breakpoints hits.

Expected Behavior

Breakpoints would hit as expected

Actual Behavior

Breakpoints were all over, not seeing transpiled code though

Reproducible Demo

See branch and file above.

Node 8 switches to the inspector protocol and some of the older scripts don't work as anticipated, I have had good luck with this launch.json

    {
      "name": "Test with debugger",
      "type": "node",
      "request": "launch",
      "runtimeArgs": ["--nolazy"],
      "program": "${workspaceRoot}/node_modules/jest/bin/jest.js",
      "args": [
        "--runInBand",
        "--transform={\"^.+\\\\.(js|jsx)$\": \"babel-jest\",\"^.+\\\\.css$\": \"jest-css\",\"^(?!.*\\\\.(js|jsx|css|json)$)\": \"jest-file\"}"
      ],
      "stopOnEntry": false,
      "sourceMaps": true,
      "console": "internalConsole",
      "cwd": "${workspaceRoot}"
    }

Wanna send a PR to fix it?

Hello @gaearon !
Absolutely, I will just check a few things to see if anything needs to be polished.

This was probably fixed in #3605.
