Any ideas how to get worker constructors into Vitest?

Trying to create an object using a constructor from the worker. However the worker types only specify interfaces, leading to the error in the screenshot.

I've tried to use the

vitest/packages/web-worker

vitest/packages/web-worker

package from https://github.com/vitest-dev/vitest/tree/main/packages/web-worker

And set up

vitest.config.js

vitest.config.js

like so:

import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    setupFiles: ['@vitest/web-worker'],
  },
})

import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    setupFiles: ['@vitest/web-worker'],
  },
})

However I'm not able to use any of the types from worker runtime it seems.

I'm trying to mock an

EmailMessage

Any ideas?
