Cannot set breakpoint for "Debug in Browser" test

Files

I have this configuration in launch.json:

        {
            "name": "Debug in Browser",
            "request": "launch",
            "type": "dart",
            "template": "debug-test",
            "args": [
                "-p",
                "chrome"
            ]            
        }

and this test file:

import 'package:test/test.dart';
void main() {
    test('read write', () async {
      expect(1, 1);
    });
}

Actions

• I can see Debug in browser command in my test file as expected.
• I set a breakpoint at expect(1, 1) line.
• When I click on the Debug in browser command I can see following compilation message in command window but no breakpoint hits

@DanTup, thanks a lot. I missed this vs code feature, everything is now easier.

Sorry for the delay in responding! The launch.json you posted is good, though you don’t really need it - if you delete the launch.json, when you press F5 it will launch on whichever device is selected in the status bar:

Clicking the device name there allows you to switch between devices (whereas the launch.json you showed will always run on Chrome, regardless of what’s selected here).

If you have any issues with this (or questions), do shout!
