Appium-Python-Client 2.1.3

Python client for Appium

Appium Python Client

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

• Enhancement
  • Updated base Selenium Python binding version to v4
    • Removed forceMjsonwp since Selenium v4 and Appium Python client v2 expect only W3C WebDriver protocol
  • Methods ActionHelpers#scroll, ActionHelpers#drag_and_drop, ActionHelpers#tap, ActionHelpers#swipe and ActionHelpers#flick now call W3C actions as its backend
    • Please check each behavior. Their behaviors could slightly differ.
  • Added strict_ssl to relax SSL error such as self-signed ones
• Deprecated
  • MultiAction and TouchAction are deprecated. Please use W3C WebDriver actions.

  • launch_app, close_app and reset are deprecated. Please read issues#15807 for more details

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 [e-mail]: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
import unittest
from appium import webdriver
from appium.webdriver.common.appiumby import AppiumBy

desired_caps = dict(
    platformName='Android',
    platformVersion='10',
    automationName='uiautomator2',
    deviceName='Android Emulator',
    app=PATH('../../../apps/selendroid-test-app.apk')
)
self.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
el = self.driver.find_element(by=AppiumBy.ACCESSIBILITY_ID, value='item')
el.click()

# iOS environment
import unittest
from appium import webdriver
from appium.webdriver.common.appiumby import AppiumBy

desired_caps = dict(
    platformName='iOS',
    platformVersion='13.4',
    automationName='xcuitest',
    deviceName='iPhone Simulator',
    app=PATH('../../apps/UICatalog.app.zip')
)

self.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
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.

import unittest
from appium import webdriver

desired_caps = dict(
    platformName='iOS',
    platformVersion='13.4',
    automationName='xcuitest',
    deviceName='iPhone Simulator',
    app=PATH('../../apps/UICatalog.app.zip')
)

self.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps, direct_connection=True)

Relax SSL validation

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

import unittest
from appium import webdriver

desired_caps = dict(
    platformName='iOS',
    platformVersion='13.4',
    automationName='xcuitest',
    deviceName='iPhone Simulator',
    app=PATH('../../apps/UICatalog.app.zip')
)

self.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps, strict_ssl=False)

Documentation
