+id: codegen
+title: "Test Generator"
+---
+
+Playwright comes with the ability to generate tests out of the box.
+
+
+
+## Generate tests
+
+```bash js
+npx playwright codegen wikipedia.org
+```
+
+```bash java
+mvn exec:java -e -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args="codegen wikipedia.org"
+```
+
+```bash python
+playwright codegen wikipedia.org
+```
+
+```bash csharp
+playwright codegen wikipedia.org
+```
+
+Run `codegen` and perform actions in the browser. Playwright will generate the code for the user interactions. `codegen` will attempt to generate resilient text-based selectors.
+
+
+
+## Preserve authenticated state
+
+Run `codegen` with `--save-storage` to save [cookies](https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies) and [localStorage](https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage) at the end of the session. This is useful to separately record authentication step and reuse it later in the tests.
+
+```bash js
+npx playwright codegen --save-storage=auth.json
+# Perform authentication and exit.
+# auth.json will contain the storage state.
+```
+
+```bash java
+mvn exec:java -e -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args="codegen --save-storage=auth.json"
+# Perform authentication and exit.
+# auth.json will contain the storage state.
+```
+
+```bash python
+playwright codegen --save-storage=auth.json
+# Perform authentication and exit.
+# auth.json will contain the storage state.
+```
+
+```bash csharp
+playwright codegen --save-storage=auth.json
+# Perform authentication and exit.
+# auth.json will contain the storage state.
+```
+
+Run with `--load-storage` to consume previously loaded storage. This way, all [cookies](https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies) and [localStorage](https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage) will be restored, bringing most web apps to the authenticated state.
+
+```bash js
+npx playwright open --load-storage=auth.json my.web.app
+npx playwright codegen --load-storage=auth.json my.web.app
+# Perform actions in authenticated state.
+```
+
+```bash java
+mvn exec:java -e -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args="open --load-storage=auth.json my.web.app"
+mvn exec:java -e -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args="codegen --load-storage=auth.json my.web.app"
+# Perform authentication and exit.
+# auth.json will contain the storage state.
+```
+
+```bash python
+playwright open --load-storage=auth.json my.web.app
+playwright codegen --load-storage=auth.json my.web.app
+# Perform actions in authenticated state.
+```
+
+```bash csharp
+playwright open --load-storage=auth.json my.web.app
+playwright codegen --load-storage=auth.json my.web.app
+# Perform actions in authenticated state.
+```
+
+## Record using custom setup
+
+If you would like to use codegen in some non-standard setup (for example, use [`method: BrowserContext.route`]), it is possible to call [`method: Page.pause`] that will open a separate window with codegen controls.
+
+```js
+const { chromium } = require('playwright');
+
+(async () => {
+ // Make sure to run headed.
+ const browser = await chromium.launch({ headless: false });
+
+ // Setup context however you like.
+ const context = await browser.newContext({ /* pass any options */ });
+ await context.route('**/*', route => route.continue());
+
+ // Pause the page, and start recording manually.
+ const page = await context.newPage();
+ await page.pause();
+})();
+```
+
+```java
+import com.microsoft.playwright.*;
+
+public class Example {
+ public static void main(String[] args) {
+ try (Playwright playwright = Playwright.create()) {
+ BrowserType chromium = playwright.chromium();
+ // Make sure to run headed.
+ Browser browser = chromium.launch(new BrowserType.LaunchOptions().setHeadless(false));
+ // Setup context however you like.
+ BrowserContext context = browser.newContext(/* pass any options */);
+ context.route("**/*", route -> route.resume());
+ // Pause the page, and start recording manually.
+ Page page = context.newPage();
+ page.pause();
+ }
+ }
+}
+```
+
+```python async
+import asyncio
+from playwright.async_api import async_playwright
+
+async def main():
+ async with async_playwright() as p:
+ # Make sure to run headed.
+ browser = await p.chromium.launch(headless=False)
+
+ # Setup context however you like.
+ context = await browser.new_context() # Pass any options
+ await context.route('**/*', lambda route: route.continue_())
+
+ # Pause the page, and start recording manually.
+ page = await context.new_page()
+ await page.pause()
+
+asyncio.run(main())
+```
+
+```python sync
+from playwright.sync_api import sync_playwright
+
+with sync_playwright() as p:
+ # Make sure to run headed.
+ browser = p.chromium.launch(headless=False)
+
+ # Setup context however you like.
+ context = browser.new_context() # Pass any options
+ context.route('**/*', lambda route: route.continue_())
+
+ # Pause the page, and start recording manually.
+ page = context.new_page()
+ page.pause()
+```
+
+```csharp
+using Microsoft.Playwright;
+using System.Threading.Tasks;
+
+class Program
+{
+ public static async Task Main()
+ {
+ using var playwright = await Playwright.CreateAsync();
+ var chromium = playwright.Chromium;
+ // Make sure to run headed.
+ var browser = await chromium.LaunchAsync(new BrowserTypeLaunchOptions { Headless = false });
+
+ // Setup context however you like.
+ var context = await browser.NewContextAsync(); // Pass any options
+ await context.RouteAsync('**/*', route => route.ContinueAsync());
+
+ // Pause the page, and start recording manually.
+ var page = await context.NewPageAsync();
+ await page.PauseAsync();
+ }
+}
+```
+
+## Emulate devices
+
+You can record scripts and tests while emulating a device.
+
+```bash js
+# Emulate iPhone 11.
+npx playwright codegen --device="iPhone 11" wikipedia.org

+
+```bash java
+# Emulate iPhone 11.
+mvn exec:java -e -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args='codegen --device="iPhone 11" wikipedia.org'

+```
+
+```bash csharp
+# Emulate iPhone 11.
+playwright codegen --device="iPhone 11" wikipedia.org
+```
+
+## Emulate color scheme and viewport size
+
+You can also record scripts and tests while emulating various browser properties.
+
+```bash js
+# Emulate screen size and color scheme.
+npx playwright codegen --viewport-size=800,600 --color-scheme=dark twitter.com
+```
+

+```
+
+```bash csharp
+# Emulate screen size and color scheme.
+playwright codegen --viewport-size=800,600 --color-scheme=dark twitter.com

+
+## Emulate geolocation, language and timezone
+
+```bash js
