Hey @FlorianWerndl have you found a workaround? I'm unable to add testing to my project.

Hi @Zachiah

this is how my config looks likes now. All unit.spec.* files are running with happy-dom and all nuxt.spec.* files with nuxt (using also happy-dom afaik).

import { defineVitestProject } from '@nuxt/test-utils/config';
import { configDefaults, defineConfig } from 'vitest/config';

export default defineConfig({
  test: {
    reporters: ['default', 'junit'],
    outputFile: './coverage/junit.xml',
    coverage: {
      provider: 'v8',
      reporter: ['text', 'json', 'html'],
      reportsDirectory: './coverage',
      include: ['app/**/**.*'],
      exclude: [
        ...(configDefaults.coverage?.exclude ?? []),
        'app/assets/**',
        'app/types/**',
        'app/utils/constants.js',
      ],
    },
    projects: [
      await defineVitestProject({
        test: {
          name: 'happy-dom',
          environment: 'happy-dom',
          globals: true,
          include: ['**/*.unit.spec.{ts,js}'],
        },
      }),
      await defineVitestProject({
        test: {
          name: 'nuxt',
          environment: 'nuxt',
          globals: true,
          include: ['**/*.nuxt.spec.{ts,js}'],
        },
      }),
    ],
    setupFiles: ['./vitest.setup.ts'],
  },
});
