# Percy playwright python
[Percy](https://percy.io) visual testing for Python Playwright.
## Installation
npm install `@percy/cli`:
```sh-session
$ npm install --save-dev @percy/cli
```
pip install Percy playwright package:
```ssh-session
$ pip install percy-playwright
```
## Usage
This is an example test using the `percy_snapshot` function.
``` python
from percy import percy_snapshot
with sync_playwright() as playwright:
browser = playwright.chromium.connect()
page = browser.new_page()
page.goto('http://example.com')
# take a snapshot
percy_snapshot(browser, 'Python example')
```
Running the test above normally will result in the following log:
```sh-session
[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 -- [python test command]
[percy] Percy has started!
[percy] Created build #1: https://percy.io/[your-project]
[percy] Snapshot taken "Python example"
[percy] Stopping percy...
[percy] Finalized build #1: https://percy.io/[your-project]
[percy] Done!
```
## Configuration
`percy_snapshot(page, name[, **kwargs])`
- `page` (**required**) - A playwright page instance
- `name` (**required**) - The snapshot name; must be unique to each snapshot
- `**kwargs` - [See per-snapshot configuration options](https://www.browserstack.com/docs/percy/take-percy-snapshots/overview#per-snapshot-configuration)
## Percy on Automate
## Usage
``` python
from playwright.sync_api import sync_playwright
from percy import percy_screenshot, percy_snapshot
desired_cap = {
'browser': 'chrome',
'browser_version': 'latest',
'os': 'osx',
'os_version': 'ventura',
'name': 'Percy Playwright PoA Demo',
'build': 'percy-playwright-python-tutorial',
'browserstack.username': 'username',
'browserstack.accessKey': 'accesskey'
}
with sync_playwright() as playwright:
cdpUrl = 'wss://cdp.browserstack.com/playwright?caps=' + urllib.parse.quote(json.dumps(desired_cap))
browser = playwright.chromium.connect(cdpUrl)
page = browser.new_page()
page.goto("https://percy.io/")
percy_screenshot(page, name = "Screenshot 1")
```
# take a snapshot
```python
percy_screenshot(page, name = 'Screenshot 1')
```
- `page` (**required**) - A Playwright page instance
- `name` (**required**) - The screenshot name; must be unique to each screenshot
- `options` (**optional**) - There are various options supported by percy_screenshot 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]
- `full_page` - Boolean value by default it falls back to `false`, Takes full page screenshot [From CLI v1.28.8]
- `freeze_animated_image` - Boolean value by default it falls back to `false`, you can pass `true` and percy will freeze image based animations.
- `freeze_image_by_selectors` -List of selectors. Images will be freezed which are passed using selectors. For this to work `freeze_animated_image` must be set to true.
- `freeze_image_by_xpaths` - List of xpaths. Images will be freezed which are passed using xpaths. For this to work `freeze_animated_image` must be set to true.
- `percy_css` - Custom CSS to be added to DOM before the screenshot being taken. Note: This gets removed once the screenshot is taken.
- `ignore_region_xpaths` - List of xpaths. elements in the DOM can be ignored using xpath
- `ignore_region_selectors` - List of selectors. elements in the DOM can be ignored using selectors.
- `custom_ignore_regions` - 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.
- `consider_region_xpaths` - List of xpaths. elements in the DOM can be considered for diffing and will be ignored by Intelli Ignore using xpaths.
- `consider_region_selectors` - List of selectors. elements in the DOM can be considered for diffing and will be ignored by Intelli Ignore using selectors.
- `custom_consider_regions` - 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 -- [python test command]
[percy] Percy has started!
[percy] [Python example] : Starting automate screenshot ...
[percy] Screenshot taken "Python example"
[percy] Stopping percy...
[percy] Finalized build #1: https://percy.io/[your-project]
[percy] Done!
```
