Thank you so much for posting this!

LEGEND! Thank you for this. I just spent way too much time trying to figure out how to be able to debug freaking typescript jest tests in a project (new job). For what it's worth, I simply:

• installed the Orta.vscode-jest plugin
• hit CMD+SHIFT+P (CTRL+SHIFT+P for PC) and chose Jest: Setup Extension > Setup Jest Debug Config
• added "runtimeExecutable": "sh", to that generated config in the launch.json

Oh and also, do NOT change the name of the auto-generated launch config. The extension appears to locate the debug configuration by that name, and that name only.

Great job!

Such configuration was not exactly working for me, but I figured out this, and it worked for me. I'm using Jest with ESM modules, pnpm, and Orta's extension (Orta.vscode-jest):

{
	"type": "node",
	"name": "vscode-jest-tests.v2",
	"request": "launch",
	"console": "integratedTerminal",
	"internalConsoleOptions": "neverOpen",
	"env": {
		"NODE_OPTIONS": "--experimental-vm-modules --no-warnings"
	},
	"runtimeExecutable": "pnpm",
	"cwd": "${workspaceFolder}",
	"args": [
		"jest",
		"-c",
		"${workspaceRoot}/jest.config.mjs",
		"--runInBand",
		"--watchAll=false",
		"--testNamePattern",
		"${jest.testNamePattern}",
		"--runTestsByPath",
		"${jest.testFile}"
	]
}

Of course, args are arbitrary and refer to the configuration I use. But this let me also debug the single tests.

BTW, I also have this in my settings.json to let it run:

{
	"jest.jestCommandLine": "NODE_OPTIONS=\"--experimental-vm-modules --no-warnings\" pnpm jest -c jest.config.mjs --runInBand"
}
