Unable to get browser tests to run

[chrisolsen]

When I run vitest --workspace ./vitest.workspace.ts I get the following error. The web server is verified to be running on port 63315.

Any ideas?

vitest.workspace.ts

import { defineWorkspace } from 'vitest/config'

export default defineWorkspace([

    extends: "./vitest.config.js",
    test: {
      name: "headless",

vitest.config.ts

import { defineConfig } from "vite";
import { svelte, vitePreprocess } from "@sveltejs/vite-plugin-svelte";

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    svelte({
      preprocess: vitePreprocess(),
      include: /\.svelte$/,
      compilerOptions: {
        customElement: true,
      },
    }),
  ],

  test: {
    exclude: [
      "**/node_modules",
    ]
  },
});

How about provider: "playwright" or headless: false?

[chrisolsen]

I created an Ubuntu devcontainer to test out Playwright and see the same issue

[hi-ogawa]

Okay, glad to know it's webdriverio specific. It would be probably quicker to diagnose if you try a minimal reproduction and provide it to us.

[chrisolsen]

The issue was also seen when using Playwright. I did get a coworker to run it on their MacBook and they also had the issue. I will try to get something put together in the next short while.

Thanks for the help

Ah, sorry I thought I wrote "it's not webdriverio specific" 😅 Yes, I'm happy to know it happens on playwright too.

Btw, do you know why you have vitest-browser-svelte in setupFileFiles? Isn't it equivalent to only directly importing what's needed by import { render } from "vitest-browser-svelte"?
