# percy-appium-python
[](https://pypi.org/project/percy-appium-app/)
[Percy](https://percy.io) visual testing for Python Appium.
## Installation
npm install `@percy/cli`:
```sh-session
$ npm install --save-dev @percy/cli
```
pip install Percy appium package:
```ssh-session
$ pip install percy-appium-app
```
> Note: This package is tested on Python versions 3.6, 3.8, 3.9 as part of unit tests. It should ideally work on all Python 3.6+ versions
[NOTE] Appium-Python-Client(>= v2.9.0) is having compatibility issues with urllib3 latest versions. To solve the issue it is recommended to add `urllib3>=1.26.15,<2` in your requirements.txt file.
## Usage
This is an example test using the `percy_screenshot` function.
``` python
from appium import webdriver
from percy import percy_screenshot
driver = webdriver.Remote("https://" + userName + ":" + accessKey + "@hub-cloud.browserstack.com/wd/hub", desired_caps)
# take a screenshot
percy_screenshot(driver, 'here is some name')
```
Running the test above normally will result in the following log:
```sh-session
[percy] Percy is not running, disabling screenshots
```
When running with [`percy
app:exec`](https://github.com/percy/cli/tree/master/packages/cli-exec#app-exec), and your project's
`PERCY_TOKEN`, a new Percy build will be created and screenshots will be uploaded to your project.
```sh-session
$ export PERCY_TOKEN=[your-project-token]
$ percy app:exec -- [python test command]
[percy] Percy has started!
[percy] Created build #1: https://percy.io/[your-project]
[percy] Screenshot taken "Python example"
[percy] Stopping percy...
[percy] Finalized build #1: https://percy.io/[your-project]
[percy] Done!
```
## Configuration
`percy_screenshot(driver, name[, **kwargs])`
- `driver` (**required**) - A appium driver instance
- `name` (**required**) - The screenshot name; must be unique to each screenshot
- `device_name` (**optional**) - The device name used for capturing screenshot

- `status_bar_height` (**optional**) - Height of status bar; int
- `nav_bar_height` (**optional**) - Height of navigation bar; int
- `sync` - Boolean value by default it falls back to `false`, Gives the processed result around screenshot [From CLI v1.28.0-beta.0+]
- `fullpage` (**optional**) - [Alpha] Only supported on App Automate driver sessions [ needs @percy/cli 1.20.2+ ]; boolean
- `screen_lengths` (**optional**) - [Alpha] Max screen lengths for fullPage; int
- In case scrollview is overlapping with other app elements. Offsets can be provided to reduce the area which needs to be considered for scrolling:
- `top_scrollview_offset`: (**optional**) - [Alpha] Offset from top of scrollview; int
- `bottom_scrollview_offset` (**optional**) - [Alpha] Offset from bottom of scrollview; int
- `full_screen` (**optional**) - Indicate whether app is full screen; boolean [ needs @percy/cli 1.20.2+ ];
- `scrollable_xpath` (**optional**) - [Alpha] Scrollable element xpath for fullpage [ needs @percy/cli 1.20.2+ ]; string
- `scrollable_id` (**optional**) - [Alpha] Scrollable element accessibility id for fullpage [ needs @percy/cli 1.20.2+ ]; string
- `ignore_regions_xpaths` (**optional**) - Elements xpaths that user want to ignore in visual diff [ needs @percy/cli 1.23.0+ ]; list of string
- `ignore_region_accessibility_ids` (**optional**) - Elements accessibility_ids that user want to ignore in visual diff [ needs @percy/cli 1.23.0+ ]; list of string
- `ignore_region_appium_elements` (**optional**) - Appium elements that user want to ignore in visual diff [ needs @percy/cli 1.23.0+ ]; list of appium element object
- `custom_ignore_regions` (**optional**) - Custom locations that user want to ignore in visual diff [ needs @percy/cli 1.23.0+ ]; list of ignore_region object
- IgnoreRegion:-
- Description: This class represents a rectangular area on a screen that needs to be ignored for visual diff.
- Constructor:
```
init(self, top, bottom, left, right)
```
- Parameters:
- `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.
## Running with Hybrid Apps
For a hybrid app, we need to switch to native context before taking screenshot.
- Add a helper method similar to following for say flutter based hybrid app:
```python
def percy_screenshot_flutter(driver, name: str, **kwargs):
driver.switch_to.context('NATIVE_APP')
percy_screenshot(driver, name, **kwargs)
driver.switch_to.context('FLUTTER')
```
- Call PercyScreenshotFlutter helper function when you want to take screenshot.
```python
percy_screenshot_flutter(driver, name, **kwargs)
```
> Note:
>
> For other hybrid apps the `driver.switch_to.context('FLUTTER')` would change to context that it uses like say WEBVIEW etc.
>
## Running Percy on Automate
`percy_screenshot(driver, name, options)` [ needs @percy/cli 1.27.0-beta.0+ ];
- `driver` (**required**) - A appium driver 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.
- `freeze_animated_image` - Boolean value by default it falls back to `false`, you can pass `true` and percy will freeze image based animations.

- In above example it will draw rectangle of consider region will be drawn.

- `bottom` (int): Bottom coordinate of the consider region.
- `left` (int): Left 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!
```
Refer to docs here: [Percy on Automate](https://www.browserstack.com/docs/percy/integrate/functional-and-visual)
### Migrating Config
If you have a previous Percy configuration file, migrate it to the newest version with the
[`config:migrate`](https://github.com/percy/cli/tree/master/packages/cli-config#percy-configmigrate-filepath-output) command:
```sh-session
$ percy config:migrate
```
