Python language bindings for Appium

Project README

Appium Python Client

PyPI version Downloads

Build Status

Code style: black

An extension library for adding WebDriver Protocol and Appium commands to the Selenium Python language binding for use with the mobile testing framework Appium.

Notice

Since v1.0.0, only Python 3.7+ is supported.

Since v2.0.0, the base selenium client version is v4. The version only works in W3C WebDriver protocol format. If you would like to use the old protocol (MJSONWP), please use v1 Appium Python client.

Quick migration guide from v1 to v2

MultiAction/TouchAction to W3C actions

On UIA2, some elements can be handled with touch pointer action insead of the default mouse pointer action in the Selenium Python cleint. For example, the below action builder is to replace the default one with the touch pointer action.

from selenium.webdriver.common.actions import interaction
from selenium.webdriver.common.actions.action_builder import ActionBuilder

actions = ActionChains(driver)
# override as 'touch' pointer action
actions.w3c_actions = ActionBuilder(driver, mouse=PointerInput(interaction.POINTER_TOUCH, "touch"))
actions.w3c_actions.pointer_action.move_to_location(start_x, start_y)
actions.w3c_actions.pointer_action.pointer_down()
actions.w3c_actions.pointer_action.pause(2)
actions.w3c_actions.pointer_action.move_to_location(end_x, end_y)
actions.w3c_actions.pointer_action.release()
actions.perform()

Getting the Appium Python client

There are three ways to install and use the Appium Python client.

  1. Install from PyPi, as 'Appium-Python-Client'.

    pip install Appium-Python-Client
    

    You can see the history from here

  2. Install from source, via PyPi. From 'Appium-Python-Client', download and unarchive the source tarball (Appium-Python-Client-X.X.tar.gz).

    tar -xvf Appium-Python-Client-X.X.tar.gz
    cd Appium-Python-Client-X.X
    python setup.py install
    
  3. Install from source via GitHub.

    git clone [email protected]:appium/python-client.git
    cd python-client
    python setup.py install
    

Usage

The Appium Python Client is fully compliant with the WebDriver Protocol including several helpers to make mobile testing in Python easier.

To use the new functionality now, and to use the superset of functions, instead of including the Selenium webdriver module in your test code, use that from Appium instead.

from appium import webdriver

From there much of your test code will work with no change.

As a base for the following code examples, the following sets up the UnitTest environment:

# Android environment
from appium import webdriver
# Options are only available since client version 2.3.0
# If you use an older client then switch to desired_capabilities
# instead: https://github.com/appium/python-client/pull/720
from appium.options.android import UiAutomator2Options
from appium.webdriver.common.appiumby import AppiumBy

options = UiAutomator2Options()
options.platformVersion = '10'
options.udid = '123456789ABC'
options.app = PATH('../../../apps/test-app.apk')
# Appium1 points to http://127.0.0.1:4723/wd/hub by default 
self.driver = webdriver.Remote('http://127.0.0.1:4723', options=options)
el = self.driver.find_element(by=AppiumBy.ACCESSIBILITY_ID, value='item')
el.click()
# iOS environment
from appium import webdriver
# Options are only available since client version 2.3.0
# If you use an older client then switch to desired_capabilities
# instead: https://github.com/appium/python-client/pull/720
from appium.options.ios import XCUITestOptions
from appium.webdriver.common.appiumby import AppiumBy

options = XCUITestOptions()
options.platformVersion = '13.4'
options.udid = '123456789ABC'
options.app = PATH('../../apps/UICatalog.app.zip')
# Appium1 points to http://127.0.0.1:4723/wd/hub by default 
self.driver = webdriver.Remote('http://127.0.0.1:4723', options=options)
el = self.driver.find_element(by=AppiumBy.ACCESSIBILITY_ID, value='item')
el.click()

Direct Connect URLs

If your Selenium/Appium server decorates the new session capabilities response with the following keys:

  • directConnectProtocol
  • directConnectHost
  • directConnectPort
  • directConnectPath

Then python client will switch its endpoint to the one specified by the values of those keys.

from appium import webdriver
# Options are only available since client version 2.3.0
# If you use an older client then switch to desired_capabilities
# instead: https://github.com/appium/python-client/pull/720
from appium.options.ios import XCUITestOptions

# load_capabilities API could be used to 
# load options mapping stored in a dictionary
options = XCUITestOptions().load_capabilities({
    'platformVersion': '13.4',
    'deviceName': 'iPhone Simulator',
    'app': PATH('../../apps/UICatalog.app.zip'),
})

self.driver = webdriver.Remote(
    # Appium1 points to http://127.0.0.1:4723/wd/hub by default 
    'http://127.0.0.1:4723', 
    options=options, 
    direct_connection=True
)

Relax SSL validation

strict_ssl option allows you to send commands to an invalid certificate host like a self-signed one.

from appium import webdriver
# Options are only available since client version 2.3.0
# If you use an older client then switch to desired_capabilities
# instead: https://github.com/appium/python-client/pull/720
from appium.options.common import AppiumOptions

options = AppiumOptions()
options.platform_name = 'mac'
options.automation_name = 'safari'
# set_capability API allows to provide any custom option
# calls to it could be chained
options.set_capability('browser_name', 'safari')

# Appium1 points to http://127.0.0.1:4723/wd/hub by default 
self.driver = webdriver.Remote('http://127.0.0.1:4723', options=options, strict_ssl=False)

Documentation
