* langs: csharp
All examples require the `Microsoft.Playwright.CLI` to be installed. You only have to do this once:
```bash
dotnet tool install -g Microsoft.Playwright.CLI
```
Playwright can install supported browsers by means of the CLI tool.
```bash js
# Running without arguments will install all browsers
npx playwright install
```
```bash java
# Running without arguments will install all browsers
mvn exec:java -e -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args="install"
```
```bash python
# Running without arguments will install all browsers
playwright install
```
```bash csharp
# Running without arguments will install all browsers
playwright install
```
You can also install specific browsers by providing an argument:
```bash js
# Install WebKit
npx playwright install webkit
```
```bash java
# Install WebKit
mvn exec:java -e -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args="install webkit"
```
```bash python
# Install WebKit
playwright install webkit
```
```bash csharp
# Install WebKit
playwright install webkit
```
See all supported browsers:
```bash js
npx playwright install --help
```
```bash java
mvn exec:java -e -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args="install --help"
```
```bash python
playwright install --help
```
```bash csharp
playwright install --help
```
## Managing browser binaries
Playwright downloads Chromium, WebKit and Firefox browsers into the OS-specific cache folders:
- `%USERPROFILE%\AppData\Local\ms-playwright` on Windows
- `~/Library/Caches/ms-playwright` on MacOS
- `~/.cache/ms-playwright` on Linux
These browsers will take a few hundred megabytes of disk space when installed:
```bash
du -hs ~/Library/Caches/ms-playwright/*
281M chromium-XXXXXX
187M firefox-XXXX
180M webkit-XXXX
```
You can override default behavior using environment variables. When installing Playwright, ask it to download browsers into a specific location:
```bash js
# Linux/macOS
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers npx playwright install
# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
npx playwright install
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"
npx playwright install
```
```bash python
# Linux/macOS
pip install playwright
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers python -m playwright install
# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
pip install playwright
playwright install
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"
pip install playwright
playwright install
```
```bash java
# Linux/macOS
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers mvn test
# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
mvn test
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"
mvn test
```
```bash csharp
# Linux/macOS

set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
playwright install
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"
playwright install
```
When running Playwright scripts, ask it to search for browsers in a shared location.
```bash js
# Linux/macOS
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers npx playwright test
# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
npx playwright test

```bash python
# Linux/macOS

# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
python playwright_script.py
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"
python playwright_script.py
```
```bash java
# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
mvn test
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"

set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
dotnet test
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"
dotnet test
```
Playwright keeps track of packages that need those browsers and will garbage collect them as you update Playwright to the newer versions.
:::note
Developers can opt-in in this mode via exporting `PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers` in their `.bashrc`.

### Managing browser binaries
* lang: js
You can opt into the hermetic install and place binaries in the local folder:
```bash
# Linux/macOS
# Places binaries to node_modules/@playwright/test
PLAYWRIGHT_BROWSERS_PATH=0 npx playwright install
# Windows with cmd.exe
# Places binaries to node_modules\@playwright\test
set PLAYWRIGHT_BROWSERS_PATH=0
npx playwright install
# Windows with PowerShell
# Places binaries to node_modules\@playwright\test
$env:PLAYWRIGHT_BROWSERS_PATH=0
npx playwright install
```
## Install behind a firewall or a proxy
By default, Playwright downloads browsers from Microsoft CDN.
Sometimes companies maintain an internal proxy that blocks direct access to the public
resources. In this case, Playwright can be configured to download browsers via a proxy server.
```bash python
# Linux/macOS
pip install playwright
HTTPS_PROXY=https://192.0.2.1 playwright install
# Windows with cmd.exe
set HTTPS_PROXY=https://192.0.2.1
pip install playwright
playwright install
# Windows with PowerShell
$env:HTTPS_PROXY="https://192.0.2.1"
pip install playwright
playwright install
```
```bash java
# Linux/macOS
HTTPS_PROXY=https://192.0.2.1 mvn test
# Windows with cmd.exe
set HTTPS_PROXY=https://192.0.2.1
mvn test
# Windows with PowerShell
$env:HTTPS_PROXY="https://192.0.2.1"
mvn test
```
```bash csharp
# Linux/macOS
HTTPS_PROXY=https://192.0.2.1 playwright install
# Windows with cmd.exe
set HTTPS_PROXY=https://192.0.2.1
playwright install
# Windows with PowerShell
$env:HTTPS_PROXY="https://192.0.2.1"
playwright install
```
## Download from artifact repository
By default, Playwright downloads browsers from Microsoft CDN.
Sometimes companies maintain an internal artifact repository to host browser
binaries. In this case, Playwright can be configured to download from a custom
location using the `PLAYWRIGHT_DOWNLOAD_HOST` env variable.
```bash python
# Linux/macOS
pip install playwright
PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1 playwright install
# Windows with cmd.exe
set PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1
pip install playwright
playwright install
# Windows with PowerShell
$env:PLAYWRIGHT_DOWNLOAD_HOST="192.0.2.1"
pip install playwright
playwright install
```
```bash java
# Linux/macOS
PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1 mvn test
# Windows with cmd.exe
set PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1
mvn test
# Windows with PowerShell
$env:PLAYWRIGHT_DOWNLOAD_HOST="192.0.2.1"
mvn test
```
```bash csharp
# Linux/macOS
PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1 playwright install
# Windows with cmd.exe
set PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1
playwright install
# Windows with PowerShell
$env:PLAYWRIGHT_DOWNLOAD_HOST="192.0.2.1"
playwright install
```
It is also possible to use a per-browser download hosts using `PLAYWRIGHT_CHROMIUM_DOWNLOAD_HOST`, `PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST` and `PLAYWRIGHT_WEBKIT_DOWNLOAD_HOST` env variables that
take precedence over `PLAYWRIGHT_DOWNLOAD_HOST`.
```bash python
# Linux/macOS
pip install playwright
PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST=203.0.113.3 PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1 python -m playwright install
```
```bash java
# Linux/macOS
PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST=203.0.113.3 PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1 mvn test
```
```bash csharp
# Linux/macOS
PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST=203.0.113.3 PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1 playwright install
```
## Skip browser downloads
In certain cases, it is desired to avoid browser downloads altogether because
browser binaries are managed separately.
This can be done by setting `PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD` variable before installation.
```bash python
# Linux/macOS
pip install playwright
PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 python -m playwright install
# Windows with cmd.exe
set PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
pip install playwright
playwright install
# Windows with PowerShell
$env:PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
pip install playwright
playwright install
```
```bash java
# Linux/macOS
PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 mvn test
# Windows with cmd.exe
set PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
mvn test
# Windows with PowerShell
$env:PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
mvn test
```
```bash csharp
# Linux/macOS
PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 playwright install
# Windows with cmd.exe
set PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
playwright install
# Windows with PowerShell
$env:PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
playwright install
```
## Download single browser binary
* langs: python
Playwright downloads Chromium, Firefox and WebKit browsers by default. To install a specific browser, pass it as an argument during installation.
```bash
pip install playwright
playwright install firefox
```
## Stale browser removal
Playwright keeps track of the clients that use its browsers. When there are no more clients that require particular
version of the browser, that version is deleted from the system. That way you can safely use Playwright instances of
different versions and at the same time, you don't waste disk space for the browsers that are no longer in use.
To opt-out from the unused browser removal, you can set the `PLAYWRIGHT_SKIP_BROWSER_GC=1` environment variable.

We call these arguments `fixtures`. Fixtures are objects that are created for each test run. Playwright Test comes loaded with those fixtures, and you can add your own fixtures as well. When running tests, Playwright Test looks at each test declaration, analyses the set of fixtures the test needs and prepares those fixtures specifically for the test.
Here is a list of the pre-defined fixtures that you are likely to use most of the time:
|Fixture |Type |Description |
|:----------|:----------------|:--------------------------------|
|page |[Page] |Isolated page for this test run. |
|context |[BrowserContext] |Isolated context for this test run. The `page` fixture belongs to this context as well. Learn how to [configure context](./test-configuration.md). |
|browser |[Browser] |Browsers are shared across tests to optimize resources. Learn how to [configure browser](./test-configuration.md). |
|browserName|[string] |The name of the browser currently running the test. Either `chromium`, `firefox` or `webkit`.|
## Test and assertion features
If you are familiar with test runners like Jest, Mocha and Ava, you will find the Playwright Test syntax familiar. These are the basic things you can do with the test:
### Focus a test
You can focus some tests. When there are focused tests, only they run.
```js js-flavor=js
test.only('focus this test', async ({ page }) => {
// Run only focused tests in the entire project.
});
```
```js js-flavor=ts
test.only('focus this test', async ({ page }) => {
// Run only focused tests in the entire project.
});
```
### Skip a test
Mark a test as skipped.
```js js-flavor=js
test.skip('skip this test', async ({ page }) => {
// This test is not run
});
```
```js js-flavor=ts
test.skip('skip this test', async ({ page }) => {
// This test is not run
});
```
You can also skip a test when [some condition is met](./test-annotations.md#conditionally-skip-a-test).
### Group tests
You can group tests to give them a logical name or to scope before/after hooks to the group.
```js js-flavor=js
const { test, expect } = require('@playwright/test');
test.describe('two tests', () => {
test('one', async ({ page }) => {
// ...
});
test('two', async ({ page }) => {
// ...
});
});
```
```js js-flavor=ts
import { test, expect } from '@playwright/test';
test.describe('two tests', () => {
test('one', async ({ page }) => {
// ...
});
test('two', async ({ page }) => {
// ...
});
});
```
### Use test hooks
You can use `test.beforeAll` and `test.afterAll` hooks to set up and tear down resources shared between tests.
And you can use `test.beforeEach` and `test.afterEach` hooks to set up and tear down resources for each test individually.
```js js-flavor=js
// example.spec.js
const { test, expect } = require('@playwright/test');
test.describe('feature foo', () => {
test.beforeEach(async ({ page }) => {
// Go to the starting url before each test.
await page.goto('https://my.start.url/');
});
test('my test', async ({ page }) => {
// Assertions use the expect API.
expect(page.url()).toBe('https://my.start.url/');
});
});
```
```js js-flavor=ts
// example.spec.ts
import { test, expect } from '@playwright/test';
test.describe('feature foo', () => {
test.beforeEach(async ({ page }) => {
// Go to the starting url before each test.
await page.goto('https://my.start.url/');
});
test('my test', async ({ page }) => {
// Assertions use the expect API.
expect(page.url()).toBe('https://my.start.url/');
});
});
```
### Write assertions
Playwright Test uses [expect](https://jestjs.io/docs/expect) library for test assertions. It provides a lot of matchers like `toEqual`, `toContain`, `toMatch`, `toMatchSnapshot` and many more.
Combine `expect` with various Playwright methods to create expectations for your test:
- [`method: Page.isVisible`]
- [`method: Page.waitForSelector`]
- [`method: Page.textContent`]
- [`method: Page.getAttribute`]
- [`method: Page.screenshot`]
- Find out more in the [assertions](./assertions.md) guide

## Managing browser binaries
Each version of Playwright needs specific versions of browser binaries to operate. By default, Playwright downloads Chromium, WebKit and Firefox browsers into the OS-specific cache folders:
- `%USERPROFILE%\AppData\Local\ms-playwright` on Windows
- `~/Library/Caches/ms-playwright` on MacOS
- `~/.cache/ms-playwright` on Linux
```bash js
npm i -D playwright
```
These browsers will take a few hundred megabytes of disk space when installed:
```bash
du -hs ~/Library/Caches/ms-playwright/*
281M chromium-XXXXXX
187M firefox-XXXX
180M webkit-XXXX
```
You can override default behavior using environment variables. When installing Playwright, ask it to download browsers into a specific location:
```bash js
# Linux/macOS
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers npm i -D playwright
# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
npm i -D playwright
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"
npm i -D playwright
```
When running Playwright scripts, ask it to search for browsers in a shared location.
```bash js
# Linux/macOS
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers node playwright-script.js
# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
node playwright-script.js
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"
node playwright-script.js
```
Or you can opt into the hermetic install and place binaries in the local folder:
```bash js
# Linux/macOS
# Places binaries to node_modules/playwright
PLAYWRIGHT_BROWSERS_PATH=0 npm i -D playwright
# Windows with cmd.exe
# Places binaries to node_modules\playwright
set PLAYWRIGHT_BROWSERS_PATH=0
npm i -D playwright
# Windows with PowerShell
# Places binaries to node_modules\playwright
$env:PLAYWRIGHT_BROWSERS_PATH=0
npm i -D playwright
```
Playwright keeps track of packages that need those browsers and will garbage collect them as you update Playwright to the newer versions.
:::note
Developers can opt-in in this mode via exporting `PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers` in their `.bashrc`.
:::
### Install behind a firewall or a proxy
By default, Playwright downloads browsers from Microsoft's CDN.
Sometimes companies maintain an internal proxy that blocks direct access to the public
resources. In this case, Playwright can be configured to download browsers via a proxy server.
```bash js
# Linux/macOS
HTTPS_PROXY=https://192.0.2.1 npm i -D playwright
# Windows with cmd.exe
set HTTPS_PROXY=https://192.0.2.1
npm i -D playwright
# Windows with PowerShell
$env:HTTPS_PROXY="https://192.0.2.1"
npm i -D playwright
```
### Download from artifact repository
By default, Playwright downloads browsers from Microsoft's CDN.
Sometimes companies maintain an internal artifact repository to host browser
binaries. In this case, Playwright can be configured to download from a custom
location using the `PLAYWRIGHT_DOWNLOAD_HOST` env variable.
```bash js
# Linux/macOS
PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1 npm i -D playwright
# Windows with cmd.exe
set PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1
npm i -D playwright
# Windows with PowerShell
$env:PLAYWRIGHT_DOWNLOAD_HOST="192.0.2.1"
npm i -D playwright
```
It is also possible to use a per-browser download hosts using `PLAYWRIGHT_CHROMIUM_DOWNLOAD_HOST`, `PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST` and `PLAYWRIGHT_WEBKIT_DOWNLOAD_HOST` env variables that
take precedence over `PLAYWRIGHT_DOWNLOAD_HOST`.
```bash js
# Linux/macOS
PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST=203.0.113.3 PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1 npm i -D playwright
```
### Skip browser downloads
In certain cases, it is desired to avoid browser downloads altogether because
browser binaries are managed separately.
This can be done by setting `PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD` variable before installation.
```bash js
# Linux/macOS
PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 npm i -D playwright
# Windows with cmd.exe
set PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
npm i -D playwright
# Windows with PowerShell
$env:PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
npm i -D playwright
```
### Download single browser binary
Playwright ships three packages that bundle only a single browser:
- [`playwright-chromium`](https://www.npmjs.com/package/playwright-chromium)
- [`playwright-webkit`](https://www.npmjs.com/package/playwright-webkit)
- [`playwright-firefox`](https://www.npmjs.com/package/playwright-firefox)
:::note
All configuration environment variables also apply to these packages.
:::
Using these packages is as easy as using a regular Playwright:
Install a specific package
```bash
npm i -D playwright-webkit
```
Require package
```js
// Notice a proper package name in require
const { webkit } = require('playwright-webkit');
(async () => {
const browser = await webkit.launch();
// ...
})();
```
### Stale browser removal
Playwright keeps track of the clients that use its browsers. When there are no more clients that require particular
version of the browser, that version is deleted from the system. That way you can safely use Playwright instances of
different versions and at the same time, you don't waste disk space for the browsers that are no longer in use.
To opt-out from the unused browser removal, you can set the `PLAYWRIGHT_SKIP_BROWSER_GC=1` environment variable.

Playwright Test uses [expect](https://jestjs.io/docs/expect) library for test assertions. This library provides
a lot of matchers like `toEqual`, `toContain`, `toMatch`, `toMatchSnapshot` and many more:
```js
expect(success).toBeTruthy();
```
Playwright also extends it with convenience async matchers that will wait until
the expected condition is met.
<!-- TOC -->
## Matching
Consider the following example:
```js
await expect(page.locator('.status')).toHaveText('Submitted');
```
Playwright Test will be re-testing the node with the selector `.status` until fetched Node has the `"Submitted"`
text. It will be re-fetching the node and checking it over and over, until the condition is met or until the timeout is
reached. You can either pass this timeout or configure it once via the [`property: Fixtures.actionTimeout`] value
in test config.
By default, the timeout for assertions is not set, so it'll wait forever, until the whole test times out.
## expect(locator).toBeChecked
- `options`
- `timeout`: <[number]> Time to retry assertion for, defaults to [`property: Fixtures.actionTimeout`].

await expect(locator).toBeFocused();
```
## expect(locator).toBeHidden

## Installing browser binaries
Each version of Playwright Test needs specific versions of browser binaries to operate. Playwright Test includes [Command Line Interface](./cli.md) that can download these binaries. By default, Playwright Test downloads Chromium, WebKit and Firefox browsers into the OS-specific cache folders:
- `%USERPROFILE%\AppData\Local\ms-playwright` on Windows
- `~/Library/Caches/ms-playwright` on MacOS
- `~/.cache/ms-playwright` on Linux
```bash
# Add dependency
npm i -D @playwright/test
# Download browser binaries
npx playwright install
```
These browsers will take a few hundred megabytes of disk space when installed:
```bash
du -hs ~/Library/Caches/ms-playwright/*
281M chromium-XXXXXX
187M firefox-XXXX
180M webkit-XXXX
```
## Installing a single browser binary
Playwright Test downloads Chromium, Firefox and WebKit browsers by default. To install a specific browser, pass it as an argument.
```bash
npx playwright install webkit
```
## Managing browser binaries
You can override default installation behavior using environment variables. When installing browsers, ask Playwright Test to download them into a specific location.
```bash
# Linux/macOS
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers npx playwright install
# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers
npx playwright install
# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"
npx playwright install
```

```bash
# Linux/macOS
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers npx playwright test
# Windows with cmd.exe
set PLAYWRIGHT_BROWSERS_PATH=%USERPROFILE%\pw-browsers

# Windows with PowerShell
$env:PLAYWRIGHT_BROWSERS_PATH="$env:USERPROFILE\pw-browsers"

```
Or you can opt into the hermetic install and place binaries in the local folder:
```bash
# Linux/macOS
# Places binaries to node_modules/@playwright/test
PLAYWRIGHT_BROWSERS_PATH=0 npx playwright install
# Windows with cmd.exe

set PLAYWRIGHT_BROWSERS_PATH=0
npx playwright install

$env:HTTPS_PROXY="https://192.0.2.1"
npx playwright install
```
## Download from artifact repository
By default, Playwright downloads browsers from Microsoft CDN.
Sometimes companies maintain an internal artifact repository to host browser
binaries. In this case, Playwright can be configured to download from a custom
location using the `PLAYWRIGHT_DOWNLOAD_HOST` env variable.
```bash
# Linux/macOS
PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1 npx playwright install
# Windows with cmd.exe
set PLAYWRIGHT_DOWNLOAD_HOST=192.0.2.1
npx playwright install
# Windows with PowerShell
$env:PLAYWRIGHT_DOWNLOAD_HOST="192.0.2.1"
npx playwright install
```
It is also possible to choose a per-browser download host using `PLAYWRIGHT_CHROMIUM_DOWNLOAD_HOST`, `PLAYWRIGHT_FIREFOX_DOWNLOAD_HOST` and `PLAYWRIGHT_WEBKIT_DOWNLOAD_HOST` env variables that
take precedence over `PLAYWRIGHT_DOWNLOAD_HOST`.
## Stale browser removal
Playwright Test keeps track of the clients that use its browsers. When there are no more clients that require particular
version of the browser, that version is deleted from the system. That way you can safely use Playwright Test instances of
different versions and at the same time, you don't waste disk space for the browsers that are no longer in use.
To opt-out from the unused browser removal, you can set the `PLAYWRIGHT_SKIP_BROWSER_GC=1` environment variable.

## Custom reporters
You can create a custom reporter by implementing a class with some of the reporter methods. Learn more about the [Reporter] API.
```js js-flavor=js
// my-awesome-reporter.js
// @ts-check
/** @implements {import('@playwright/test/reporter').Reporter} */
class MyReporter {
onBegin(config, suite) {
console.log(`Starting the run with ${suite.allTests().length} tests`);
}
onTestBegin(test) {
console.log(`Starting test ${test.title}`);
}
onTestEnd(test, result) {
console.log(`Finished test ${test.title}: ${result.status}`);
}
onEnd(result) {
console.log(`Finished the run: ${result.status}`);
}
}
module.exports = MyReporter;
```
```js js-flavor=ts
// playwright.config.ts
import { Reporter } from '@playwright/test/reporter';
class MyReporter implements Reporter {
onBegin(config, suite) {
console.log(`Starting the run with ${suite.allTests().length} tests`);
}
onTestBegin(test) {
console.log(`Starting test ${test.title}`);
}
onTestEnd(test, result) {
console.log(`Finished test ${test.title}: ${result.status}`);
}
onEnd(result) {
console.log(`Finished the run: ${result.status}`);
}
}
export default MyReporter;
```
Now use this reporter with [`property: TestConfig.reporter`].
```js js-flavor=js
// playwright.config.js
// @ts-check
/** @type {import('@playwright/test').PlaywrightTestConfig} */
const config = {
reporter: './my-awesome-reporter.js',
};
module.exports = config;
```
```js js-flavor=ts
// playwright.config.ts
import { PlaywrightTestConfig } from '@playwright/test';
const config: PlaywrightTestConfig = {
reporter: './my-awesome-reporter.ts',
};
export default config;
```
## Third party showcase
- Allure reporter
```bash
# Install
npm i -D experimental-allure-playwright
# Run tests
npx playwright test --reporter=line,experimental-allure-playwright

* **Timeout-free automation**. Playwright receives browser signals, like network requests, page navigations and page load events to eliminate the need for sleep timeouts that cause flakiness.
* **Lean parallelization with browser contexts**. Reuse a single browser instance for multiple parallelized, isolated execution environments with [browser contexts](./core-concepts.md).
* **Lean parallelization with Playwright Test Runner**. Zero configuration [parallel tests](./test-parallel.md).
* **Fast isolation with browser contexts**. Reuse a single browser instance for multiple isolated execution environments with [browser contexts](./core-concepts.md).
* **Resilient element selectors**. Playwright can rely on user-facing strings, like text content and accessibility labels to [select elements](./selectors.md). These strings are more resilient than selectors tightly-coupled to the DOM structure.
@ -35,27 +37,8 @@ Playwright enables fast, reliable and capable automation across all modern brows
* **Capabilities to cover all scenarios**. Support for [file downloads](./downloads.md) and [uploads](./input.md), out-of-process iframes, native [input events](./input.md), and even [dark mode](./emulation.md).
## Integrates with your workflow
* **One-line installation**. Installing Playwright auto-downloads browser dependencies for your team to be onboarded quickly.
```bash js
npm i playwright
```
```bash python
pip install playwright
playwright install
```
* **TypeScript support**. Playwright ships with built-in types for auto-completion and other benefits.
* **Debugging tools**. Playwright works with the [editor debugger and browser developer tools](./debug.md) to pause execution and inspect the web page.
* **Language bindings**. Playwright is available for [Node.js](https://github.com/microsoft/playwright) [Python](https://github.com/microsoft/playwright-python), [.NET](https://github.com/microsoft/playwright-dotnet) and
[Java](https://github.com/microsoft/playwright-java). Learn more about [supported languages](./languages.md).
* **Deploy tests to CI**. First-party [Docker image](./docker.md) and [GitHub Actions](./ci.md#github-actions) support to deploy tests to [your preferred CI/CD provider](./ci.md).
## Limitations
* **Legacy Edge and IE11 support**. Playwright does not support legacy Microsoft Edge or IE11 ([deprecation notice](https://techcommunity.microsoft.com/t5/microsoft-365-blog/microsoft-365-apps-say-farewell-to-internet-explorer-11-and/ba-p/1591666)). The new Microsoft Edge (on Chromium) is supported.
* **Test on real mobile devices**: Playwright uses desktop browsers to emulate mobile devices. There is experimental Android support available see [here](https://playwright.dev/docs/mobile). If you are interested in iOS, please [upvote this issue](https://github.com/microsoft/playwright/issues/1122).
