Playwright is a testing framework that lets you automate Chromium, Firefox, and WebKit with a single API. You can use it to write **End-to-End (E2E)** testing. This guide will show you how to set up Playwright with Next.js and write your first tests.
|
||
|
|
|
||
|
|
## Quickstart
|
||
|
|
|
||
|
|
The fastest way to get started is to use `create-next-app` with the [with-playwright example](https://github.com/vercel/next.js/tree/canary/examples/with-playwright). This will create a Next.js project complete with Playwright configured.
|
||
|
|
|
||
|
|
```bash package="pnpm"
|
||
|
|
pnpm create next-app --example with-playwright with-playwright-app
|
||
|
|
```
|
||
|
|
|
||
|
|
```bash package="npm"
|
||
|
|
npx create-next-app@latest --example with-playwright with-playwright-app
|
||
|
|
```
|
||
|
|
|
||
|
|
```bash package="yarn"
|
||
|
|
yarn create next-app --example with-playwright with-playwright-app
|
||
|
|
```
|
||
|
|
|
||
|
|
```bash package="bun"
|
||
|
|
bun create next-app --example with-playwright with-playwright-app
|
||
|
|
```
|
||
|
|
|
||
|
|
## Manual setup
|
||
|
|
|
||
|
|
To install Playwright, run the following command:
|
||
|
|
|
||
|
|
```bash package="pnpm"
|
||
|
|
pnpm create playwright
|
||
|
|
```
|
||
|
|
|
||
|
|
```bash package="npm"
|
||
|
|
npm init playwright
|
||
|
|
```
|
||
|
|
|
||
|
|
```bash package="yarn"
|
||
|
|
yarn create playwright
|
||
|
|
```
|
||
|
|
|
||
|
|
```bash package="bun"
|
||
|
|
bun create playwright
|
||
|
|
```
|
||
|
|
|
||
|
|
This will take you through a series of prompts to setup and configure Playwright for your project, including adding a `playwright.config.ts` file. Please refer to the [Playwright installation guide](https://playwright.dev/docs/intro#installation) for the step-by-step guide.
|
||
|
|
|
||
|
|
## Creating your first Playwright E2E test
|
||
|
|
|
||
|
|
Create two new Next.js pages:
|
||
|
|
|
||
|
|
<AppOnly>
|
||
|
|
|
||
|
|
```tsx filename="app/page.tsx"
|
||
|
|
import Link from 'next/link'
|
||
|
|
|
||
|
|
export default function Page() {
|
||
|
|
return (
|
||
|
|
<div>
|
||
|
|
<h1>Home</h1>
|
||
|
|
<Link href="/about">About</Link>
|
||
|
|
</div>
|
||
|
|
)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
```tsx filename="app/about/page.tsx"
|
||
|
|
import Link from 'next/link'
|
||
|
|
|
||
|
|
export default function Page() {
|
||
|
|
return (
|
||
|
|
<div>
|
||
|
|
<h1>About</h1>
|
||
|
|
<Link href="/">Home</Link>
|
||
|
|
</div>
|
||
|
|
)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
</AppOnly>
|
||
|
|
|
||
|
|
<PagesOnly>
|
||
|
|
|
||
|
|
```tsx filename="pages/index.ts"
|
||
|
|
import Link from 'next/link'
|
||
|
|
|
||
|
|
export default function Home() {
|
||
|
|
return (
|
||
|
|
<div>
|
||
|
|
<h1>Home</h1>
|
||
|
|
<Link href="/about">About</Link>
|
||
|
|
</div>
|
||
|
|
)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
```tsx filename="pages/about.ts"
|
||
|
|
import Link from 'next/link'
|
||
|
|
|
||
|
|
export default function About() {
|
||
|
|
return (
|
||
|
|
<div>
|
||
|
|
<h1>About</h1>
|
||
|
|
<Link href="/">Home</Link>
|
||
|
|
</div>
|
||
|
|
)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
</PagesOnly>
|
||
|
|
|
||
|
|
Then, add a test to verify that your navigation is working correctly:
|
||
|
|
|
||
|
|
```ts filename="tests/example.spec.ts"
|
||
|
|
import { test, expect } from '@playwright/test'
|
||
|
|
|
||
|
|
test('should navigate to the about page', async ({ page }) => {
|
||
|
|
// Start from the index page (the baseURL is set via the webServer in the playwright.config.ts)
|
||
|
|
await page.goto('http://localhost:3000/')
|
||
|
|
// Find an element with the text 'About' and click on it
|
||
|
|
await page.click('text=About')
|
||
|
|
// The new URL should be "/about" (baseURL is used there)
|
||
|
|
await expect(page).toHaveURL('http://localhost:3000/about')
|
||
|
|
// The new page should contain an h1 with "About"
|
||
|
|
await expect(page.locator('h1')).toContainText('About')
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
> **Good to know**: You can use `page.goto("/")` instead of `page.goto("http://localhost:3000/")`, if you add [`"baseURL": "http://localhost:3000"`](https://playwright.dev/docs/api/class-testoptions#test-options-base-url) to the `playwright.config.ts` [configuration file](https://playwright.dev/docs/test-configuration).
|
||
|
|
|
||
|
|
### Running your Playwright tests
|
||
|
|
|
||
|
|
Playwright will simulate a user navigating your application using three browsers: Chromium, Firefox and Webkit, this requires your Next.js server to be running. We recommend running your tests against your production code to more closely resemble how your application will behave.
|
||
|
|
|
||
|
|
Run `npm run build` and `npm run start`, then run `npx playwright test` in another terminal window to run the Playwright tests.
|
||
|
|
|
||
|
|
> **Good to know**: Alternatively, you can use the [`webServer`](https://playwright.dev/docs/test-webserver/) feature to let Playwright start the development server and wait until it's fully available.
|
||
|
|
|
||
|
|
### Running Playwright on Continuous Integration (CI)
|
||
|
|
|
||
|
|
Playwright will by default run your tests in the [headless mode](https://playwright.dev/docs/ci#running-headed). To install all the Playwright dependencies, run `npx playwright install-deps`.
|
||
|
|
