ava: vscode debug + typescript recipes are incompatible as authored

Please provide details about:

What you’re trying to do

debug tests, in typescript, ts-node only

What happened

Test executed successfully, but both breakpoints & debugger statements ignored

What you expected to happen

debugger statements to halt execution

• per using-ts-node, some TS configuration is needed in package.json. i’ve added:

  "ava": {
    "extensions": [
      "ts"
    ],
    "require": [
      "ts-node/register/transpile-only"
    ],
    "files": [
      "test/**/*.test.ts"
    ]
  }

• per creating-a-launch-configuration, various launch configuration is required:

    {
      "type": "node",
      "request": "launch",
      "name": "Debug AVA test file",
      "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/ava",
      "runtimeArgs": ["${file}"],
      "outputCapture": "std"
      // "skipFiles": ["<node_internals>/**/*.js"] // i've disabled simply to remove more variables
    }

Interestingly, I can get into a breakpoint if I execute a alternate debugging workflow:

• npx ava debug test/class.test.ts
• Attach a debugger

Works fine 😃

Previously, ava entered a debug session via more idiomatic node debug conventions–node --inspect <path/to/ava/profile.js> <test name>. It seems like now ava is doing some fancy footwork, where it wants to start the node debugger, where VSCode also wants to start the debugger, and consequently these two things may be trampling each other a bit.

I don’t have a minimal repro, but it’s a pretty straightforward repro:

• git clone https://github.com/cdaringe/factorio-ts
• git checkout 7cbc8e9
• yarn
• execute the VSCode launch as recorded above
• observe.

We’ll also need your AVA configuration (in package.json or ava.config.* configuration files) and how you’re invoking AVA. Share the installed AVA version (get it by running npx ava --version).

Shared above, but here’s also envinfo output:
