-## Launching a development web server during the tests
-
-To launch a server during the tests, use the `launch` option in the [configuration file](#configuration-object).
-
-You can specify a port via `waitForPort` or additional environment variables, see [here](#configuration-object). When a port is specified, the server will wait for it to be available before starting. For continuous integration, you may want to use the `strict` option which ensures that the port is available before starting the server.
-
-The port gets then passed over to Playwright as a [`param: baseURL`] when creating the context [`method: Browser.newContext`].
-
-```js js-flavor=ts
-// playwright.config.ts
-import { PlaywrightTestConfig } from '@playwright/test';
-
-const config: PlaywrightTestConfig = {
-  launch: {
-    command: 'npm run start',
-    waitForPort: 3000,
-    waitForPortTimeout: 120 * 1000,
-    strict: !!process.env.CI,
-  },
-};
-
-export default config;
-```
-
-```js js-flavor=js
-// playwright.config.js
-// @ts-check
-/** @type {import('@playwright/test').PlaywrightTestConfig} */
-const config = {
-  launch: {
-    command: 'npm run start',
-    waitForPort: 3000,
-    waitForPortTimeout: 120 * 1000,
-    strict: !!process.env.CI,
-  },
-};
-
-mode.exports = config;
-```
-
-Now you can use a relative path when navigating the page, or use `baseURL` fixture:
-
-```js js-flavor=ts
-// test.spec.ts
-import { test } = from '@playwright/test';
-
-test('test', async ({ page, baseURL }) => {
-  // baseURL is taken directly from your web server,
-  // e.g. http://localhost:3000
-  await page.goto(baseURL + '/bar');
-
-  // Alternatively, just use relative path, because baseURL is already
-  // set for the default context and page.
-  // For example, this will result in http://localhost:3000/foo
-  await page.goto('/foo');
-});
-```
-
-```js js-flavor=js
-// test.spec.js
-const { test } = require('@playwright/test');
-
-test('test', async ({ page, baseURL }) => {
-  // baseURL is taken directly from your web server,
-  // e.g. http://localhost:3000
-  await page.goto(baseURL + '/bar');
-
-  // Alternatively, just use relative path, because baseURL is already
-  // set for the default context and page.
-  // For example, this will result in http://localhost:3000/foo
-  await page.goto('/foo');
-});

 ## Global setup and teardown
 
 To set something up once before running all tests, use `globalSetup` option in the [configuration file](#configuration-object).

 - `testMatch`: Glob patterns or regular expressions that match test files. For example, `'**/todo-tests/*.spec.ts'`. By default, Playwright Test runs `.*(test|spec)\.(js|ts|mjs)` files.
