Facebook WebDriverAgent Python Client Library (not official)

Most functions finished.

Implemented apis describe in https://github.com/facebook/WebDriverAgent/wiki/Queries

This library has been used in project atx https://github.com/NetEaseGame/AutomatorX

Installation

1. You need to start WebDriverAgent by yourself

   Follow the instructions in https://github.com/facebook/WebDriverAgent

   It is better to start with Xcode to prevent CodeSign issues.

   But it is also ok to start WDA with command line.

   xcodebuild -project WebDriverAgent.xcodeproj -scheme WebDriverAgentRunner -destination 'platform=iOS Simulator,name=iPhone 6' test
   
   

   WDA在真机上运行需要一些配置，可以参考这篇文章 ATX 文档 - iOS 真机如何安装 WebDriverAgent

2. Install python wda client

   pip install --pre facebook-wda
   
   

TCP connection over USB (optional)

You can use wifi network, it is very convinient, but not very stable enough.

I found a tools named iproxy which can forward device port to localhost, it's source code is here https://github.com/libimobiledevice/libusbmuxd

The usage is very simple iproxy <local port> <remote port> [udid]

Something you need to know

function window_size() return UIKit size, While screenshot() image size is Native Resolution

[图片上传失败...(image-36fd39-1545569833470)]

when use screenshot, the image size is pixels size. eg(1080 x 1920) But this size is different with c.session().window_size()

use session.scale to get UIKit scale factor

Configuration

import wda

wda.DEBUG = False # default False
wda.HTTP_TIMEOUT = 60.0 # default 60.0 seconds

How to use

Create a client

import wda

# Enable debug will see http Request and Response
# wda.DEBUG = True
c = wda.Client('http://localhost:8100')

# get env from $DEVICE_URL if no arguments pass to wda.Client
# http://localhost:8100 is the default value if $DEVICE_URL is empty
c = wda.Client()

A wda.WDAError will be raised if communite with WDA went wrong.

Client

# Show status
print c.status()

# Wait WDA ready
c.wait_ready(timeout=300) # 等待300s，默认120s

# Press home button
c.home()

# Hit healthcheck
c.healthcheck()

# Get page source
c.source() # format XML
c.source(accessible=True) # default false, format JSON

Take screenshot, only can save format png

c.screenshot('screen.png')

Open app

with c.session('com.apple.Health') as s:
    print s.orientation

Same as

s = c.session('com.apple.Health')
print s.orientation
s.close()

For web browser like Safari you can define page whit which will be opened:

s = c.session('com.apple.mobilesafari', ['-u', 'https://www.google.com/ncr'])
print s.orientation
s.close()

Session operations

# Current bundleId and sessionId
print s.bundle_id, s.id

# Screenshot return PIL.Image
# Requires pillow, installed by "pip install pillow"
s.screenshot().save("s.png")

# Sometimes screenshot rotation is wrong, but we can rotate it to the right direction
# Refs: https://pillow.readthedocs.io/en/3.1.x/reference/Image.html#PIL.Image.Image.transpose
from PIL import Image
s.screenshot().transpose(Image.ROTATE_90).save("correct.png")

# One of <PORTRAIT | LANDSCAPE>
print(s.orientation) # expect PORTRAIT or LANDSCAPE

# Change orientation
s.orientation = wda.LANDSCAPE # there are many other directions

# Deactivate App for some time
s.deactivate(5.0) # 5s

# Get width and height
print(s.window_size())
# Expect tuple output (width, height)
# For example: (414, 736)

# Get UIKit scale factor, the first time will take about 1s, next time use cached value
print(s.scale)
# Example output: 3

# Simulate touch
s.tap(200, 200)

# Very like tap, but support float and int argument
s.click(200, 200)
s.click(0.5, 0.5) # click center of screen
s.click(0.5, 200) # click center of x, and y(200)

# Double touch
s.double_tap(200, 200)

# Simulate swipe, utilizing drag api
s.swipe(x1, y1, x2, y2, 0.5) # 0.5s
s.swipe_left()
s.swipe_right()
s.swipe_up()
s.swipe_down()

# tap hold
s.tap_hold(x, y, 1.0)

# Hide keyboard (not working in simulator), did not success using latest WDA
s.keyboard_dismiss()

Find element

Note: if element not found, WDAElementNotFoundError will be raised

# For example, expect: True or False
# using id to find element and check if exists
s(id="URL").exists # return True or False

# using id or other query conditions
s(id='URL')
s(name='URL')
s(text="URL") # text is alias of name
s(nameContains='UR')
s(label='Address')
s(labelContains='Addr')
s(name='URL', index=1) # find the second element. index starts from 0

# combines search conditions
# attributes bellow can combines
# :"className", "name", "label", "visible", "enabled"
s(className='Button', name='URL', visible=True, labelContains="Addr")

More powerful findding method

s(xpath='//Button[@name="URL"]')
s(classChain='**/Button[`name == "URL"`]')
s(predicate='name LIKE "UR*"')
s('name LIKE "U*L"') # predicate is the first argument, without predicate= is ok

Element operations (eg: tap, scroll, set_text etc...)

Exmaple search element and tap

# Get first match Element object
# The function get() is very important.
# when elements founded in 10 seconds(:default:), Element object returns
# or WDAElementNotFoundError raises
e = s(text='Dashboard').get(timeout=10.0)
# s(text='Dashboard') is Selector
# e is Element object
e.tap() # tap element

Some times, I just hate to type .get()

Using python magic tricks to do it again.

#   using python magic function "__getattr__", it is ok with out type "get()"
s(text='Dashboard').tap()
# same as
s(text='Dashboard').get().tap()

Note: Python magic tricks can not used on get attributes

# Accessing attrbutes, you have to use get()
s(text='Dashboard').get().value

# Not right
# s(text='Dashboard').value # Bad, always return None

Click element if exists

s(text='Dashboard').click_exists() # return immediately if not found
s(text='Dashboard').click_exists(timeout=5.0) # wait for 5s

Other Element operations

# Check if elements exists
print s(text="Dashboard").exists

# Find all matches elements, return Array of Element object
s(text='Dashboard').find_elements()

# Use index to find second element
s(text='Dashboard')[1].exists

# Use child to search sub elements
s(text='Dashboard').child(className='Cell').exists

# Default timeout is 10 seconds
# But you can change by
s.set_timeout(10.0)

# do element operations
e.tap()
e.click() # alias of tap
e.clear_text()
e.set_text("Hello world")
e.tap_hold(2.0) # tapAndHold for 2.0s

e.scroll() # scroll to make element visiable

# directions can be "up", "down", "left", "right"
# swipe distance default to its height or width according to the direction
e.scroll('up')

# Set text
e.set_text("Hello WDA") # normal usage
e.set_text("Hello WDA\n") # send text with enter
e.set_text("\b\b\b") # delete 3 chars

# Wait element gone
s(text='Dashboard').wait_gone(timeout=10.0)

# Swipe
s(className="Image").swipe("left")

# Pinch
s(className="Map").pinch(2, 1) # scale=2, speed=1
s(className="Map").pinch(0.1, -1) # scale=0.1, speed=-1 (I donot very understand too)

# properties (bool)
e.accessible
e.displayed
e.enabled

# properties (str)
e.text # ex: Dashboard
e.className # ex: XCUIElementTypeStaticText
e.value # ex: github.com

# Bounds return namedtuple
rect = e.bounds # ex: Rect(x=144, y=28, width=88.0, height=27.0)
rect.x # expect 144

Alert

print s.alert.exists
print s.alert.text
s.alert.accept() # Actually do click first alert button
s.alert.dismiss() # Actually do click second alert button
s.alert.wait(5) # if alert apper in 5 second it will return True,else return False (default 20.0)
s.alert.wait() # wait alert apper in 2 second

s.alert.buttons()
# example return: ["设置", "好"]

s.alert.click("设置")

TODO

longTap not done pinch(not found in WDA)

TouchID

• Match Touch ID
• Do not match Touch ID

How to handle alert message automaticly (need more tests)

For example

import wda

s = wda.Client().session()

def _alert_callback(session):
    session.alert.accept()

s.set_alert_callback(_alert_callback)

# do operations, when alert popup, it will auto accept
s(type="Button").click()

iOS Build-in Apps

苹果自带应用

第三方应用 Thirdparty

Another way to list apps installed on you phone is use ideviceinstaller install with brew install ideviceinstaller

List apps with command

$ ideviceinstaller -l

Tests

测试的用例放在tests/目录下，使用iphone SE作为测试机型，系统语言应用。调度框架pytest
