Describe the bug

I can't get debugging a test to work using your extension in VS Code when the test is configured to use a real browser.
I've had various errors (been trying to get this working for days), but for the sake of reproducible steps, I tried it using one of your own sample projects. It is a bit of a long story, but after all the rabbit trails, the short version is that I got to where it launches a browser and runs the test, but apparently, even after I added sourceMap:true, it can't find a place to set my breakpoint.

Reproduction

  • installed your extension
  • cloned https://github.com/vitest-dev/vscode.git
  • various messy stuff to get pnpm installed (using volta)
  • pnpm install
  • restarted VS code
  • testing tab shows only a few of the samples.
  • Picked the "add" test in samples\basic-v4\test\add.test.ts
  • Set a breakpoint in it
  • used the green arrow to debug that test
  • all well: hits breakpoint
  • modified the corresponding basic-v4\vitest.config.ts, adding
test: {
    ...
	browser: {
      enabled: true,
    },
  • surprising result: vitest extension green arrows disappear from add.tests.ts; the whole basic-v4 sample disappears from the TESTING window; no obvious message tells me why I can't test it any more
  • tried variations on vitest.config.ts, such as
test: {
    include: ['src/should_included_test.ts', 'test/**/*.test.ts'],
    exclude: ['test/ignored.test.ts'],
    browser: {
      enabled: true,
      // Configure browser options
      instances: [
        {
          name: 'chromium',
        },

      ]
    },
  },
  • no change
  • (discovered and ran) npx vitest init browser. Chose Typescript, playwright, chromium, vanilla, yes (install playwright browsers)
  • Many more sample projects in TESTING window. basic-v4 came back. vitest extension arrows came back in add.tests.ts
  • tried debugging the test
  • breakpoint is not hit, and test does not appear to run. Only obvious result is a popup saying "Failed to report coverage. [birpc] rpc is closed, cannot call "waitForCoverageReport". Check the output for more details.". There is nothing in the output window. Nothing new in terminal window. Test Results window just says "The test run did not record any output." Debug console says "C:\Program Files\Volta\node.EXE .....\Users\Thomson.vscode\extensions\vitest.explorer-1.28.2\dist\worker.js
    Process exited with code 1"

I tried several variations on vitest.config.ts with the same result. The one I thought most likely to work was

/// <reference types="vitest" />

// Configure Vitest (https://vitest.dev/config)

import { defineConfig } from 'vite'

export default defineConfig({
  esbuild: {
    target: 'es2022',
  },
  test: {
    include: ['src/should_included_test.ts', 'test/**/*.test.ts'],
    exclude: ['test/ignored.test.ts'],
    browser: {
      enabled: true,
      // Configure browser options
      instances: [
        {
          name: 'chromium',
          provider: {
            name: 'playwright',
          },
        },

      ]
    },
  },
})
  • starting to report the bug, I discovered "Show Vitest Output Channel". Now there is all sorts of information in output, which I will attach. Following a suggestion there, I ran
  • npx playwright install
  • now, when I try to debug the test, a browser comes up, and the test appears to run. I can get a red X by changing the expected result. However, it still doesn't hit my breakpoint.
    If I'm very fast, while the test is running and the red breakpoint symbol changes to a hollow white one, I can get into the Debug Diagnostics tool, and ask it why my breakpoint doesn't bind. It says,
	✅ This breakpoint was initially set in:

	C:\github\vscode\samples\basic-v4\test\add.test.ts line 6 column 1

	❓ We couldn't find a corresponding source location, and didn't find any source with the name add.test.ts.

	How did you expect this file to be loaded? (If you have a compilation step, you should pick 'sourcemap')
	Loaded in directlyBe parsed from a sourcemap
	Here's some hints that might help you:
	Make sure you have "sourceMap": true in your tsconfig to generate sourcemaps.
  • (this struck me as strange. Apparently it can find add.test.ts to report that the breakpoint was set there, but then can't find any such file at some later point)
  • tried setting sourceMap:true in tsconfig.base.json
    (If this is necessary, it would be nice if at least your samples already had it.)
  • made no difference.

In my own project, I tried various other things. AI suggested that Chrome might need to be configured to debug on port 9229, so I tried

providerOptions: {
	launch: {
		args: ["--remote-debugging-port=9229"]
	}
}

AIs also suggested various things to put in launch.json. None helped.
The most common result, once I got playwright installed, is that nothing happens when I set a breakpoint and try to debug, except for the message about "Failed to report coverage".
Before installing playwright (trying to run tests directly in the browser), I've also seen the green-arrow command list change after the first attempt to Debug, with that option disappearing and "Debug all" wrongly added to the single arrow for a single test.
I also saw cases where a browser was launched and showed messages indicating it was trying to connect but did not succeed.

If this isn't a bug and I'm just doing something wrong, it would be very helpful to add to your documentation on this extension a detailed set of steps for debugging using a browser to run the tests. You can probably also tell, from the sad history above, that there are a lot of places where more helpful error information could be provided.
