vitest with AnalogJS angular-vite-plugin | Error: No test suite found in file

I have a monorepo with an Angular project and a few Node.js projects.

Running vitest locally, all tests are passing. However, in GitHub Actions, the Angular tests are failing.

GitHub Actions test error

Here is my vitest config:

vitest.config.mts


/// <reference types="vitest" />
/* eslint-disable no-restricted-globals */

import angular from '@analogjs/vite-plugin-angular'
import path from 'nodeath'
import { defineConfig } from 'vite'
import viteTsConfigPaths from 'vite-tsconfig-paths'

const PROJECT_NAME = 'angular-project'

declare global {
namespace NodeJS {
interface ProcessEnv {
GITHUB_ACTIONS?: string
}
}
}

export default defineConfig({
root: 'apps/angular-project',

plugins: [
angular(),
viteTsConfigPaths({
projects: ['../../tsconfig.base.json', './tsconfig.json', './tsconfig.spec.json'],
}),
],

})


By commenting out the angular() plugin, the error No test suite found in file is resolved, but then all of the tests fail, since vitest doesn't support Angular out of the box (as of January 2025).
