# @percy/playwright
[](https://npmjs.org/package/@percy/playwright)
[Percy](https://percy.io) visual testing for Playwright.
## Installation
```sh-session
$ npm install --save-dev @percy/cli @percy/playwright
```
## Usage
This is an example using the `percySnapshot` function. For other examples of `playwright`
usage, see the [Playwright docs](https://playwright.dev/docs/library).
```javascript
const { chromium } = require('playwright');
const percySnapshot = require('@percy/playwright');
(async () => {
const browser = await chromium.launch();
const page = await browser.newPage();
await page.goto('http://example.com/', { waitUntil: 'networkidle2' });
await percySnapshot(page, 'Example Site');
await browser.close();
})();
```
Running the code above directly will result in the following logs:
```sh-session
$ node script.js
[percy] Percy is not running, disabling snapshots
```
When running with [`percy
exec`](https://github.com/percy/cli/tree/master/packages/cli-exec#percy-exec), and your project's
`PERCY_TOKEN`, a new Percy build will be created and snapshots will be uploaded to your project.
```sh-session
$ export PERCY_TOKEN=[your-project-token]
$ percy exec -- node script.js
[percy] Percy has started!
[percy] Created build #1: https://percy.io/[your-project]
[percy] Running "node script.js"
[percy] Snapshot taken "Example Site"
[percy] Stopping percy...
[percy] Finalized build #1: https://percy.io/[your-project]
[percy] Done!
```
## Configuration
`percySnapshot(page, name[, options])`
- `page` (**required**) - A `playwright` page instance
- `name` (**required**) - The snapshot name; must be unique to each snapshot
- `options` - [See per-snapshot configuration options](https://www.browserstack.com/docs/percy/take-percy-snapshots/overview#per-snapshot-configuration)
## Percy on Automate
## Usage
```javascript
const { chromium } = require('playwright');
const percyScreenshot = require('@percy/playwright');
const desired_cap = {
'browser': 'chrome',
'browser_version': 'latest',
'os': 'osx',
'os_version': 'ventura',
'name': 'Percy Playwright PoA Demo',
'build': 'percy-playwright-javascript-tutorial',
'browserstack.username': 'username',
'browserstack.accessKey': 'accesskey'
};
(async () => {
const cdpUrl = `wss://cdp.browserstack.com/playwright?caps=${encodeURIComponent(JSON.stringify(desired_cap))}`;
const browser = await chromium.connect(cdpUrl);
const page = await browser.newPage();
await page.goto("https://percy.io/");
await percyScreenshot(page, 'Screenshot 1');
// Options for percyScreenshot
// await percyScreenshot(page, 'Screenshot 1', {
// fullPage: true,
// percyCSS: 'body { background: red; }',
// ignoreRegionSelectors: ['#ignore-this'],
// customIgnoreRegions: [{ top: 10, right: 10, bottom: 120, left: 10 }],
// });
await browser.close();
})();
```
## Configuration
`percyScreenshot(page, name[, options])`
- `page` (**required**) - A `playwright` page instance
- `name` (**required**) - The snapshot name; must be unique to each snapshot
- `options` (**optional**) - There are various options supported by percyScreenshot to server further functionality.
- `sync` - Boolean value by default it falls back to `false`, Gives the processed result around screenshot [From CLI v1.28.8+]
- `fullPage` - Boolean value by default it falls back to `false`, Takes full page screenshot [From CLI v1.27.6+]
- `freezeAnimatedImage` - Boolean value by default it falls back to `false`, you can pass `true` and percy will freeze image based animations.
- `freezeImageBySelectors` - List of selectors. Images will be freezed which are passed using selectors. For this to work `freezeAnimatedImage` must be set to true.
- `freezeImageByXpaths` - List of xpaths. Images will be freezed which are passed using xpaths. For this to work `freezeAnimatedImage` must be set to true.
- `percyCSS` - Custom CSS to be added to DOM before the screenshot being taken. Note: This gets removed once the screenshot is taken.
- `ignoreRegionXpaths` - List of xpaths. elements in the DOM can be ignored using xpath
- `ignoreRegionSelectors` - List of selectors. elements in the DOM can be ignored using selectors.
- `customIgnoreRegions` - List of custom objects. elements can be ignored using custom boundaries. Just passing a simple object for it like below.
- example: ```{top: 10, right: 10, bottom: 120, left: 10}```
- In above example it will draw rectangle of ignore region as per given coordinates.
- `top` (int): Top coordinate of the ignore region.
- `bottom` (int): Bottom coordinate of the ignore region.
- `left` (int): Left coordinate of the ignore region.
- `right` (int): Right coordinate of the ignore region.
- `considerRegionXpaths` - List of xpaths. elements in the DOM can be considered for diffing and will be ignored by Intelli Ignore using xpaths.
- `considerRegionSelectors` - List of selectors. elements in the DOM can be considered for diffing and will be ignored by Intelli Ignore using selectors.
- `customConsiderRegions` - List of custom objects. elements can be considered for diffing and will be ignored by Intelli Ignore using custom boundaries
- example: ```{top: 10, right: 10, bottom: 120, left: 10}```
- In above example it will draw rectangle of consider region will be drawn.
- Parameters:
- `top` (int): Top coordinate of the consider region.
- `bottom` (int): Bottom coordinate of the consider region.
- `left` (int): Left coordinate of the consider region.
- `right` (int): Right coordinate of the consider region.
### Creating Percy on automate build
Note: Automate Percy Token starts with `auto` keyword. The command can be triggered using `exec` keyword.
```sh-session
$ export PERCY_TOKEN=[your-project-token]
$ percy exec -- [playwright test command]
[percy] Percy has started!
[percy] [Playwright example] : Starting automate screenshot ...
[percy] Screenshot taken "Playwright example"
[percy] Stopping percy...
[percy] Finalized build #1: https://percy.io/[your-project]
[percy] Done!
```
