Describe the bug

I am trying to test a file that relies on environment variables, though it doesn't load them. I use vite+vitest with React.js. It works well on development/production, but when I test the component with the variable is undefined: import.meta.env.VITE_API_URL

When I initialize the test, it loads properly on my vite.config.js:

export default ({ mode }) => {
  process.env = { ...process.env, ...loadEnv(mode, process.cwd()) }
  console.log('mode', mode, loadEnv(mode, process.cwd())) <----- HERE IT APPEARS TO BE DEFINED WHEN THE TEST STARTS
  return defineConfig({
    base: '/',
    server: {
      port: 3000,
      proxy: {
        '/public': {
          target: `${process.env.VITE_API_URL}/`,
          changeOrigin: true,
        },
      },
    },
    publicDir: './public',
    plugins: [react()],
    test: {
      globals: true,
      environment: 'jsdom',
      setupFiles: './src/__test__/setup.js',
      include: ['./src/__test__/**/*.{test,spec}.{js,mjs,cjs,ts,mts,cts,jsx,tsx}'],
    },
  })
}

Reproduction

1. Create react app with vite-react template
2. Add vitest
3. Create .env with some environment variables
4. Create a file that uses the variable
5. Test the file and that the variable is present
