percy-appium-app 1.1.0

Python client for visual testing with Percy for mobile apps

percy-appium-python

Percy visual testing for Python Appium.

Installation

npm install @percy/cli:

$ npm install --save-dev @percy/cli

pip install Percy appium package:

$ 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

Usage

This is an example test using the percy_screenshot function.

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:

[percy] Percy is not running, disabling screenshots

When running with percy app:exec, and your project's PERCY_TOKEN, a new Percy build will be created and screenshots will be uploaded to your project.

$ 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!
