Vitest failed to find the current suite.

[dvnrsn]

What is the location of your example repository?

Use getting started defaults

Which package or tool is having this issue?

Oxygen

What version of that package or tool are you using?

"@shopify/mini-oxygen": "^3.0.5",

What version of Remix are you using?

"@remix-run/react": "^2.10.1",

Steps to Reproduce

In adding Vitest to quickstart project, I experience

Error: Vitest failed to find the current suite. This is a bug in Vitest. Please, open an issue with reproduction.

I've isolated this to the mini-oxygen plugin as when I comment it out, vitetest works as desired

// vite.config.js

import {oxygen} from '@shopify/mini-oxygen/vite';
import {vitePlugin as remix} from '@remix-run/dev';
import tsconfigPaths from 'vite-tsconfig-paths';

export default defineConfig({
  plugins: [
    hydrogen(),
    // oxygen(),
    remix({
      presets: [hydrogen.preset()],
      future: {
        v3_fetcherPersist: true,
        v3_relativeSplatPath: true,
        v3_throwAbortReason: true,
      },
    }),

Expected Behavior

Vitest should run successfully

Actual Behavior

Vitest breaks with error

Thanks for raising this @dvnrsn. I'm able to replicate.

Is there any update on this or a workaround?

[Zeindelf]

It's a issue with Vitest on Remix. Currently workaround need to create a separate file to load Vitest config and omit all Remix/Vite/Oxygen plugins.

// vitest.config.ts <- new root file

/// <reference types="vitest" />
/// <reference types="vite/client" />
import {defineConfig} from 'vite';
import tsconfigPaths from 'vite-tsconfig-paths';

export default defineConfig({
  plugins: [tsconfigPaths()],
  test: {
    coverage: {
      all: true,
      include: ['app/**'],
    },
    environment: 'jsdom',
    globals: true,
    include: ['./app/**/*.{test,spec}.{js,mjs,cjs,ts,jsx,tsx}'],
    setupFiles: ['PATH/TO/SETUP_FILES'],
  },
});
