Latest upgrade to Version 1.19.1 (1.19.1) breaks Jest Test Debugging Capabilities

[Dimomir]

• VSCode Version: Version 1.19.1 (1.19.1)
• OS Version: OS X El Capitan 10.11.6 (15G1421)

Hi there, I suspect the newest update might be breaking the Jest debugging. Here's my config taken straight from Jest's website: .

Note: I'm using the CRA setup

{
      "name": "Debug CRA Tests",
      "type": "node",
      "request": "launch",
      "runtimeExecutable": "${workspaceRoot}/client/node_modules/.bin/react-scripts",
      "runtimeArgs": ["--inspect-brk", "test"],
      "args": ["--runInBand", "--no-cache", "--env=jsdom"],
      "cwd": "${workspaceRoot}/client",
      "protocol": "inspector",
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen"
}

Steps to Reproduce:

When I try to start debugging (which I can confirm was working with previous versions) I now get the error:
Error: Cannot connect to runtime process, timeout after 10000 ms - (reason: Cannot connect to the target: connect ECONNREFUSED 127.0.0.1:3269).

Could you please point me to what I'm missing?

duplicate of #40254.

The launch config from Jest's website is wrong.
Use this launch config:

{
      "name": "Debug CRA Tests",
      "type": "node",
      "request": "launch",
      "runtimeExecutable": "${workspaceRoot}/client/node_modules/.bin/react-scripts",
      "args": [ "test", "--runInBand", "--no-cache", "--env=jsdom" ],
      "cwd": "${workspaceRoot}/client",
      "protocol": "inspector",
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen"
}

I can confirm the above solution works 👌

Thank you kindly for your time @weinand

For those that ended up here because VSCode debugging for jest on windows STILL doesn't work, try the following:

        {
          "name": "Debug Jest Tests",
          "type": "node",
          "request": "launch",
          "runtimeArgs": [
              "--inspect-brk=5555",
              "${workspaceRoot}/node_modules/jest/bin/jest.js"
          ],
          "args": [
              "--runInBand",
          ],
          "port": 5555,
          "protocol": "inspector",
          "console": "integratedTerminal",
          "internalConsoleOptions": "neverOpen"
        }

@Phlow2001 this (simpler) launch config should be equivalent for VS Code > 1.19:

        {
          "name": "Debug Jest Tests",
          "type": "node",
          "request": "launch",
          "program": "${workspaceFolder}/node_modules/jest/bin/jest.js",
          "args": [
              "--runInBand",
          ],
          "protocol": "inspector",
          "console": "integratedTerminal",
          "internalConsoleOptions": "neverOpen"
        }

And you only need the "protocol" attribute if you are using node.js < 8.0
