Playwright can be used to automate scenarios that require authentication.
Tests written with Playwright execute in isolated clean-slate environments called
[browser contexts](./core-concepts.md#browser-contexts). This isolation model
[browser contexts](./browser-contexts.md). This isolation model
improves reproducibility and prevents cascading test failures. New browser
contexts can load existing authentication state. This eliminates the need to
login in every context and speeds up test execution.

## Browser context
A [BrowserContext] is an isolated incognito-alike session within a browser instance. Browser contexts are fast and
cheap to create. We recommend running each test scenario in its own new Browser context, so that
the browser state is isolated between the tests. If you are using [Playwright Test](./intro.md), this happens out of the
box for each test. Otherwise, you can create browser contexts manually:
```js
const browser = await chromium.launch();
const context = await browser.newContext();
const page = await context.newPage();
```
```java
Browser browser = chromium.launch();
BrowserContext context = browser.newContext();
Page page = context.newPage();
```
```python async
browser = await playwright.chromium.launch()
context = await browser.new_context()
page = await context.new_page()
```
```python sync
browser = playwright.chromium.launch()
context = browser.new_context()
page = context.new_page()
```
```csharp
await using var browser = playwright.Chromium.LaunchAsync();
var context = await browser.NewContextAsync();
var page = await context.NewPageAsync();
```
Browser contexts can also be used to emulate multi-page scenarios involving
mobile devices, permissions, locale and color scheme.
```js
const { devices } = require('playwright');
const iPhone = devices['iPhone 11 Pro'];
const context = await browser.newContext({
...iPhone,
permissions: ['geolocation'],
geolocation: { latitude: 52.52, longitude: 13.39},
colorScheme: 'dark',
locale: 'de-DE'
});
const page = await context.newPage();
```
```java
// FIXME
import com.microsoft.playwright.*;
public class Example {
public static void main(String[] args) {
try (Playwright playwright = Playwright.create()) {
BrowserType devices = playwright.devices();
BrowserContext context = browser.newContext(new Browser.NewContextOptions()
.setUserAgent("Mozilla/5.0 (iPhone; CPU iPhone OS 12_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0 Mobile/15E148 Safari/604.1")
.setViewportSize(375, 812)
.setDeviceScaleFactor(3)
.setIsMobile(true)
.setHasTouch(true)
.setPermissions(Arrays.asList("geolocation"))
.setGeolocation(52.52, 13.39)
.setColorScheme(ColorScheme.DARK)
.setLocale("de-DE"));
Page page = context.newPage();
}
}
}
```
```python async
import asyncio
from playwright.async_api import async_playwright
async def main():
async with async_playwright() as p:
iphone_11 = p.devices['iPhone 11 Pro']
browser = await p.chromium.launch()
context = await browser.new_context(
**iphone_11,
locale='de-DE',
geolocation={ 'longitude': 12.492507, 'latitude': 41.889938 },
permissions=['geolocation'],
color_scheme='dark',
)
page = await browser.new_page()
await browser.close()
asyncio.run(main())
```
```python sync
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
iphone_11 = p.devices['iPhone 11 Pro']
browser = p.webkit.launch(headless=False)
context = browser.new_context(
**iphone_11,
locale='de-DE',
geolocation={ 'longitude': 12.492507, 'latitude': 41.889938 },
permissions=['geolocation']
)
page = context.new_page()
browser.close()
```
```csharp
using Microsoft.Playwright;
using System.Threading.Tasks;
class PlaywrightExample
{
public static async Task Main()
{
using var playwright = await Playwright.CreateAsync();
await using var browser = await playwright.Webkit.LaunchAsync();
var options = new BrowserNewContextOptions(playwright.Devices["iPhone 11 Pro"])
{
Geolocation = new() { Longitude = 12.492507f, Latitude = 41.889938f },
Permissions = new[] { "geolocation" },
Locale = "de-DE"
};
await using var context = await browser.NewContextAsync(options);
var page = await browser.NewPageAsync();
}
}
```
## Multiple contexts
[Browser contexts](./browser-contexts.md) are isolated environments on a single browser instance.
Playwright can create multiple browser contexts within a single scenario. This is useful when you want to test for
multi-user functionality, like chat.
```js
const { chromium } = require('playwright');
// Create a Chromium browser instance
const browser = await chromium.launch();
// Create two isolated browser contexts
const userContext = await browser.newContext();
const adminContext = await browser.newContext();
// Create pages and interact with contexts independently
```
```java
import com.microsoft.playwright.*;
public class Example {
public static void main(String[] args) {
try (Playwright playwright = Playwright.create()) {
BrowserType chromium = playwright.chromium();
// Create a Chromium browser instance
Browser browser = chromium.launch();
// Create two isolated browser contexts
BrowserContext userContext = browser.newContext();
BrowserContext adminContext = browser.newContext();
// Create pages and interact with contexts independently
}
}
}
```
```python async
import asyncio
from playwright.async_api import async_playwright
async def run(playwright):
# create a chromium browser instance
chromium = playwright.chromium
browser = await chromium.launch()
# create two isolated browser contexts
user_context = await browser.new_context()
admin_context = await browser.new_context()
# create pages and interact with contexts independently
async def main():
async with async_playwright() as playwright:
await run(playwright)
asyncio.run(main())
```
```python sync
from playwright.sync_api import sync_playwright
def run(playwright):
# create a chromium browser instance
chromium = playwright.chromium
browser = chromium.launch()
# create two isolated browser contexts
user_context = browser.new_context()
admin_context = browser.new_context()
# create pages and interact with contexts independently
with sync_playwright() as playwright:
run(playwright)
```
```csharp
using Microsoft.Playwright;
using System.Threading.Tasks;
class Program
{
public static async Task Main()
{
using var playwright = await Playwright.CreateAsync();
// Create a Chromium browser instance
await using var browser = await playwright.Chromium.LaunchAsync();
await using var userContext = await browser.NewContextAsync();
await using var adminContext = await browser.NewContextAsync();
// Create pages and interact with contexts independently.
}
}
```

id: evaluating
title: "Evaluating JavaScript"
---
Playwright scripts run in your Playwright environment. Your page scripts run in the browser page environment. Those environments don't intersect, they are running in different virtual machines in different processes and even potentially on different computers.
The [`method: Page.evaluate`] API can run a JavaScript function in the context
of the web page and bring results back to the Playwright environment. Browser globals like
`window` and `document` can be used in `evaluate`.
```js
const href = await page.evaluate(() => document.location.href);
```
```java
String href = (String) page.evaluate("document.location.href");
```
```python async
href = await page.evaluate('() => document.location.href')
```
```python sync
href = page.evaluate('() => document.location.href')
```
```csharp
var href = await page.EvaluateAsync<string>("document.location.href");
```
If the result is a Promise or if the function is asynchronous evaluate will automatically wait until it's resolved:
```js
const status = await page.evaluate(async () => {
const response = await fetch(location.href);
return response.status;
});
```
```java
int status = (int) page.evaluate("async () => {\n" +
" const response = await fetch(location.href);\n" +
" return response.status;\n" +
"}");
```
```python async
status = await page.evaluate("""async () => {
response = await fetch(location.href)
return response.status
}""")
```
```python sync
status = page.evaluate("""async () => {
response = fetch(location.href)
return response.status
}""")
```
```csharp
int status = await page.EvaluateAsync<int>(@"async () => {
const response = await fetch(location.href);
return response.status;
}");
```
## Evaluation Argument
Playwright evaluation methods like [`method: Page.evaluate`] take a single optional argument. This argument can be a mix of [Serializable] values and [JSHandle] or [ElementHandle] instances. Handles are automatically converted to the value they represent.
```js
// A primitive value.
await page.evaluate(num => num, 42);
// An array.
await page.evaluate(array => array.length, [1, 2, 3]);
// An object.
await page.evaluate(object => object.foo, { foo: 'bar' });
// A single handle.
const button = await page.$('button');
await page.evaluate(button => button.textContent, button);
// Alternative notation using elementHandle.evaluate.
await button.evaluate((button, from) => button.textContent.substring(from), 5);
// Object with multiple handles.
const button1 = await page.$('.button1');
const button2 = await page.$('.button2');
await page.evaluate(
o => o.button1.textContent + o.button2.textContent,
{ button1, button2 });
// Object destructuring works. Note that property names must match
// between the destructured object and the argument.
// Also note the required parenthesis.
await page.evaluate(
({ button1, button2 }) => button1.textContent + button2.textContent,
{ button1, button2 });
// Array works as well. Arbitrary names can be used for destructuring.
// Note the required parenthesis.
await page.evaluate(
([b1, b2]) => b1.textContent + b2.textContent,
[button1, button2]);
// Any non-cyclic mix of serializables and handles works.
await page.evaluate(
x => x.button1.textContent + x.list[0].textContent + String(x.foo),
{ button1, list: [button2], foo: null });
```
```java
// A primitive value.
page.evaluate("num => num", 42);
// An array.
page.evaluate("array => array.length", Arrays.asList(1, 2, 3));
// An object.
Map<String, Object> obj = new HashMap<>();
obj.put("foo", "bar");
page.evaluate("object => object.foo", obj);
// A single handle.
ElementHandle button = page.querySelector("button");
page.evaluate("button => button.textContent", button);
// Alternative notation using elementHandle.evaluate.
button.evaluate("(button, from) => button.textContent.substring(from)", 5);
// Object with multiple handles.
ElementHandle button1 = page.querySelector(".button1");
ElementHandle button2 = page.querySelector(".button2");
Map<String, ElementHandle> arg = new HashMap<>();
arg.put("button1", button1);

## Frames
A [Page] can have one or more [Frame] objects attached to it. Each page has a main frame and page-level interactions
(like `click`) are assumed to operate in the main frame.
A page can have additional frames attached with the `iframe` HTML tag. These frames can be accessed for interactions
inside the frame.
```js
// Locate element inside frame
const username = await page.frameLocator('.frame-class').locator('#username-input');
await username.fill('John');
```
```java
// Locate element inside frame
Locator username = page.frameLocator(".frame-class").locator("#username-input");
username.fill("John");
```
```python async
# Locate element inside frame
username = await page.frame_locator('.frame-class').locator('#username-input')
await username.fill('John')
```
```python sync
# Locate element inside frame
# Get frame using any other selector
username = page.frame_locator('.frame-class').locator('#username-input')
username.fill('John')
```
```csharp
// Locate element inside frame
var username = await page.FrameLocator(".frame-class").Locator("#username-input");
await username.FillAsync("John");
```
## Frame objects
One can access frame objects using the [`method: Page.frame`] API:
```js
// Get frame using the frame's name attribute
const frame = page.frame('frame-login');
// Get frame using frame's URL
const frame = page.frame({ url: /.*domain.*/ });
// Get frame using any other selector
const frameElementHandle = await page.$('.frame-class');
const frame = await frameElementHandle.contentFrame();
// Interact with the frame
await frame.fill('#username-input', 'John');
```
```java
// Get frame using the frame"s name attribute
Frame frame = page.frame("frame-login");
// Get frame using frame"s URL
Frame frame = page.frameByUrl(Pattern.compile(".*domain.*"));
// Get frame using any other selector
ElementHandle frameElementHandle = page.querySelector(".frame-class");
Frame frame = frameElementHandle.contentFrame();
// Interact with the frame
frame.fill("#username-input", "John");
```
```python async
# Get frame using the frame's name attribute
frame = page.frame('frame-login')
# Get frame using frame's URL
frame = page.frame(url=r'.*domain.*')
# Get frame using any other selector
frame_element_handle = await page.query_selector('.frame-class')
frame = await frame_element_handle.content_frame()
# Interact with the frame
await frame.fill('#username-input', 'John')
```
```python sync
# Get frame using the frame's name attribute
frame = page.frame('frame-login')
# Get frame using frame's URL
frame = page.frame(url=r'.*domain.*')
# Get frame using any other selector
frame_element_handle = page.query_selector('.frame-class')
frame = frame_element_handle.content_frame()
# Interact with the frame
frame.fill('#username-input', 'John')
```
```csharp
// Create a page.
var page = await context.NewPageAsync();
// Get frame using the frame's name attribute
var frame = page.Frame("frame-login");
// Get frame using frame's URL
var frame = page.FrameByUrl("*domain.");
// Get frame using any other selector
var frameElementHandle = await page.QuerySelectorAsync(".frame-class");
var frame = await frameElementHandle.ContentFrameAsync();
// Interact with the frame
await frame.FillAsync("#username-input", "John");

Playwright can automate scenarios that span multiple browser contexts or multiple tabs in a browser window.
<!-- TOC -->
## Multiple contexts
## Pages
[Browser contexts](./core-concepts.md#browser-contexts) are isolated environments on a single browser instance.
Playwright can create multiple browser contexts within a single scenario. This is useful when you want to test for
multi-user functionality, like chat.
Each [BrowserContext] can have multiple pages. A [Page] refers to a single tab or a popup window within a browser
context. It should be used to navigate to URLs and interact with the page content.
```js
const { chromium } = require('playwright');
// Create a page.
const page = await context.newPage();
// Create a Chromium browser instance
const browser = await chromium.launch();
// Navigate explicitly, similar to entering a URL in the browser.
await page.goto('http://example.com');
// Fill an input.
await page.locator('#search').fill('query');
// Create two isolated browser contexts
const userContext = await browser.newContext();
const adminContext = await browser.newContext();
// Create pages and interact with contexts independently
// Navigate implicitly by clicking a link.
await page.locator('#submit').click();
// Expect a new url.
console.log(page.url());
```
```java
import com.microsoft.playwright.*;
// Create a page.
Page page = context.newPage();

public static void main(String[] args) {
try (Playwright playwright = Playwright.create()) {

BrowserContext userContext = browser.newContext();
BrowserContext adminContext = browser.newContext();
// Create pages and interact with contexts independently
}
}
}
// Navigate explicitly, similar to entering a URL in the browser.
page.navigate("http://example.com");
// Fill an input.
page.locator("#search").fill("query");
// Navigate implicitly by clicking a link.
page.locator("#submit").click();
// Expect a new url.
System.out.println(page.url());
```
