Fails to run tests with federated module

[adarshdeep-ld]

Describe the bug

Hey folks, I found a problem that I don't know how to solve. I'm using module federation (@originjs/vite-plugin-federation) to get a remote module and since I've added config my tests are failing,

Here is my config:

export default defineConfig(() => ({
  plugins: [
    ElementPlus(),
    vue(),
    federation({
      name: 'team-red',
      remotes: {
        "team-blue": "http://localhost:5002/assets/remoteEntry.js",
        "team-green": "http://localhost:5001/assets/remoteEntry.js",
      },
      shared: ['vue','pinia']
  })
  ],
  build:{
    minify: false,
    target: ["chrome89", "edge89", "firefox89", "safari15"],
  },
  test: {
    globals: true,
    environment: "happy-dom",
    include: ["./src/**/*.{test,spec}.?(c|m)[jt]s?(x)"], 
  },
}))

I have just tried to mount the component that uses remote components and it gives the following error:

So is there any way to work around it and get my test working?

Not familiar with module federation ideas, but I'm guessing the whole point of module federation is to not have to unit test entire modules.

If that's the case, they might simply recommend skipping their plugin during unit test by:

plugins: [
  ...,
  !process.env.VITEST && federation({ ... }),
]

Probably, it's better to ask on their end about what's the recommendation.
