Basic Playwright setup not working in Sveltkit

When i run npm test after timeout i get these results:

Running 0 tests using 0 workers[Webserver]... some unused css selectors messages[WebServer]Error: Timed out waiting 60000ms from config.webServer.

I did research on google. But materials are very limited and could not resolve my problem.npm test:unit works.

I am out of ideas what can i do. Below is information about the files.

playwright.config.js

/ @type {import('@playwright/test').PlaywrightTestConfig} */const config = {    webServer: {        command: 'npm run build && npm run preview',        port: 4173    },    testDir: 'uat',    timeout: 6000};export default config;

svelte.config.js

import adapter from '@sveltejs/adapter-node';import { vitePreprocess } from '@sveltejs/kit/vite';/ @type {import('@sveltejs/kit').Config} /const config = {    onwarn: (warning, handler) => {    if (warning.code.startsWith('a11y-')) {      return;    }    handler(warning);  },    preprocess: [vitePreprocess()],    kit: {        adapter: adapter()    }};export default config;

vite.config.js

import { sveltekit } from '@sveltejs/kit/vite'import { socketPlugin } from './server/socket_plugin.js'const config = {    server: {        port: 3000    },    preview: {        port: 3000    },    plugins: [        sveltekit(),        socketPlugin    ],    test: {        include: ['src/**/.{test,spec}.{js,ts}']    }}export default config;
