xiaocong/uiautomator: Python wrapper of Android uiautomator test tool.

This module is a Python wrapper of Android uiautomator testing framework. It works on Android 4.1+ (API Level 16~30) simply with Android device attached via adb, no need to install anything on Android device.

from uiautomator import device as d

d.screen.on()
d(text="Clock").click()

Installation

$ pip install uiautomator

Pre-requirements

Install Android SDK, and set ANDROID_HOME environment to the correct path.
Enable ADB setting on device and connect your android device using usb with your PC.
Allow apps to install from unknown sources on device settings.

import uiautomator

If ANDROID_SERIAL is defined in environment, or there is only one device connected:
```
from uiautomator import device as d
```

Speficy the serial number when retrieving the device object

from uiautomator import Device

d = Device('014E05DE0F02000E')

Speficy the adb server host and port running on other computer

Although adb supports -a option since SDK 4.3, but now it has a bug on it. The only way to start adb server listenning on all interfaces instead of localhost, is adb -a -P 5037 fork-server server &
```
from uiautomator import Device

d = Device('014E05DE0F02000E', adb_server_host='192.168.1.68', adb_server_port=5037)
```

Notes: In below examples, we use d represent the android device object.

Basic API Usages

This part show the normal actions of the device through some simple examples.

Retrieve the device info

Below is a possible result:

{ u'displayRotation': 0,
  u'displaySizeDpY': 640,
  u'displaySizeDpX': 360,
  u'currentPackageName': u'com.android.launcher',
  u'productName': u'takju',
  u'displayWidth': 720,
  u'sdkInt': 18,
  u'displayHeight': 1184,
  u'naturalOrientation': True
}

Key Event Actions of the device

Turn on/off screen

# Turn on screen
d.screen.on()
# Turn off screen
d.screen.off()

Alternative method is:

# wakeup the device
d.wakeup()
# sleep the device, same as turning off the screen.
d.sleep()

Check if the screen is on or off

if d.screen == "on":  # of d.screen != "off"
    # do something in case of screen on
    pass
if d.screen == "off":  # of d.screen != "on"
    # do something in case of screen off
    pass

Press hard/soft key

# press home key
d.press.home()
# press back key
d.press.back()
# the normal way to press back key
d.press("back")
# press keycode 0x07('0') with META ALT(0x02) on
d.press(0x07, 0x02)

Next keys are currently supported:
- home
- back
- left
- right
- up
- down
- center
- menu
- search
- enter
- delete(or del)
- recent(recent apps)
- volume_up
- volume_down
- volume_mute
- camera
- power
You can find all key code definitions at Android KeyEvent.

Gesture interaction of the device

Click the screen
```
# click (x, y) on screen
d.click(x, y)
```

Long click the screen

# long click (x, y) on screen
d.long_click(x, y)

Swipe

# swipe from (sx, sy) to (ex, ey)
d.swipe(sx, sy, ex, ey)
# swipe from (sx, sy) to (ex, ey) with 10 steps
d.swipe(sx, sy, ex, ey, steps=10)

Drag

# drag from (sx, sy) to (ex, ey)
d.drag(sx, sy, ex, ey)
# drag from (sx, sy) to (ex, ey) with 10 steps
d.drag(sx, sy, ex, ey, steps=10)

Screen Actions of the device

Retrieve/Set Orientation

The possible orientation is:

natural or n
left or l
right or r
upsidedown or u (can not be set)

# retrieve orientation, it may be "natural" or "left" or "right" or "upsidedown"
orientation = d.orientation
# set orientation and freeze rotation.
# notes: "upsidedown" can not be set until Android 4.3.
d.orientation = "l" # or "left"
d.orientation = "r" # or "right"
d.orientation = "n" # or "natural"

Freeze/Un-Freeze rotation

# freeze rotation
d.freeze_rotation()
# un-freeze rotation
d.freeze_rotation(False)

Take screenshot

# take screenshot and save to local file "home.png", can not work until Android 4.2.
d.screenshot("home.png")

Dump Window Hierarchy

# dump the widown hierarchy and save to local file "hierarchy.xml"
d.dump("hierarchy.xml")
# or get the dumped content(unicode) from return.
xml = d.dump()

Open notification or quick settings

# open notification, can not work until Android 4.3.
d.open.notification()
# open quick settings, can not work until Android 4.3.
d.open.quick_settings()

Wait for idle or window update

# wait for current window to idle
d.wait.idle()
# wait until window update event occurs
d.wait.update()

Watcher

You can register watcher to perform some actions when a selector can not find a match.

When a selector can not find a match, uiautomator will run all registered watchers.

Click target when conditions match

d.watcher("AUTO_FC_WHEN_ANR").when(text="ANR").when(text="Wait") \
                             .click(text="Force Close")
# d.watcher(name) ## creates a new named watcher.
#  .when(condition)  ## the UiSelector condition of the watcher.
#  .click(target)  ## perform click action on the target UiSelector.

Press key when conditions match

d.watcher("AUTO_FC_WHEN_ANR").when(text="ANR").when(text="Wait") \
                             .press.back.home()
# Alternative way to define it as below
d.watcher("AUTO_FC_WHEN_ANR").when(text="ANR").when(text="Wait") \
                             .press("back", "home")
# d.watcher(name) ## creates a new named watcher.
#  .when(condition)  ## the UiSelector condition of the watcher.
#  .press.<keyname>.....<keyname>.()  ## press keys one by one in sequence.
#  Alternavie way defining key sequence is press(<keybname>, ..., <keyname>)

Check if the named watcher triggered

A watcher is triggered, which means the watcher was run and all its conditions matched.
```
d.watcher("watcher_name").triggered
# true in case of the specified watcher triggered, else false
```

Remove named watcher

# remove the watcher
d.watcher("watcher_name").remove()

List all watchers

d.watchers
# a list of all registered wachers' names

Check if there is any watcher triggered

d.watchers.triggered
#  true in case of any watcher triggered

Reset all triggered watchers

# reset all triggered watchers, after that, d.watchers.triggered will be false.
d.watchers.reset()

Remvoe watchers

# remove all registered watchers
d.watchers.remove()
# remove the named watcher, same as d.watcher("watcher_name").remove()
d.watchers.remove("watcher_name")

Force to run all watchers

# force to run all registered watchers
d.watchers.run()

Handler

The functionality of handler is same as Watcher, except it is implemented ourside of Android uiautomator. The most different usage between handler and watcher is, handler can use customized callback function.

def fc_close(device):
  if device(text='Force Close').exists:
    device(text='Force Close').click()
  return True  # return True means to break the loop of handler callback functions.

# turn on the handler callback function
d.handlers.on(fc_close)

# turn off the handler callback function
d.handlers.off(fc_close)

Selector

Selector is to identify specific ui object in current window.

# To seleted the object ,text is 'Clock' and its className is 'android.widget.TextView'
d(text='Clock', className='android.widget.TextView')

Selector supports below parameters. Refer to UiSelector java doc for detailed information.

text, textContains, textMatches, textStartsWith
className, classNameMatches
description, descriptionContains, descriptionMatches, descriptionStartsWith
checkable, checked, clickable, longClickable
scrollable, enabled,focusable, focused, selected
packageName, packageNameMatches
resourceId, resourceIdMatches
index, instance

Child and sibling UI object

child

# get the child or grandchild
d(className="android.widget.ListView").child(text="Bluetooth")

sibling

# get sibling or child of sibling
d(text="Google").sibling(className="android.widget.ImageView")

child by text or description or instance

# get the child match className="android.widget.LinearLayout"
# and also it or its child or grandchild contains text "Bluetooth"
d(className="android.widget.ListView", resourceId="android:id/list") \
 .child_by_text("Bluetooth", className="android.widget.LinearLayout")

# allow scroll search to get the child
d(className="android.widget.ListView", resourceId="android:id/list") \
 .child_by_text(
    "Bluetooth",
    allow_scroll_search=True,
    className="android.widget.LinearLayout"
  )

child_by_description is to find child which or which's grandchild contains the specified description, others are the same as child_by_text.
child_by_instance is to find child which has a child UI element anywhere within its sub hierarchy that is at the instance specified. It is performed on visible views without scrolling.

See below links for detailed information:

UiScrollable, getChildByDescription, getChildByText, getChildByInstance
UiCollection, getChildByDescription, getChildByText, getChildByInstance

Above methods support chained invoking, e.g. for below hierarchy

<node index="0" text="" resource-id="android:id/list" class="android.widget.ListView" ...>
  <node index="0" text="WIRELESS & NETWORKS" resource-id="" class="android.widget.TextView" .../>
  <node index="1" text="" resource-id="" class="android.widget.LinearLayout" ...>
    <node index="1" text="" resource-id="" class="android.widget.RelativeLayout" ...>
      <node index="0" text="Wi‑Fi" resource-id="android:id/title" class="android.widget.TextView" .../>
    </node>
    <node index="2" text="ON" resource-id="com.android.settings:id/switchWidget" class="android.widget.Switch" .../>
  </node>
  ...
</node>

We want to click the switch at the right side of text 'Wi‑Fi' to turn on/of Wi‑Fi. As there are several switches with almost the same properties, so we can not use like d(className="android.widget.Switch") to select the ui object. Instead, we can use code below to select it.

d(className="android.widget.ListView", resourceId="android:id/list") \
  .child_by_text("Wi‑Fi", className="android.widget.LinearLayout") \
  .child(className="android.widget.Switch") \
  .click()

relative position

Also we can use the relative position methods to get the view: left, right, top, bottom.
- d(A).left(B), means selecting B on the left side of A.
- d(A).right(B), means selecting B on the right side of A.
- d(A).up(B), means selecting B above A.
- d(A).down(B), means selecting B under A.
So for above case, we can write code alternatively:
```
## select "switch" on the right side of "Wi‑Fi"
d(text="Wi‑Fi").right(className="android.widget.Switch").click()
```

Multiple instances

Sometimes the screen may contain multiple views with the same e.g. text, then you will have to use "instance" properties in selector like below:

d(text="Add new", instance=0)  # which means the first instance with text "Add new"

However, uiautomator provides list like methods to use it.

# get the count of views with text "Add new" on current screen
d(text="Add new").count

# same as count property
len(d(text="Add new"))

# get the instance via index
d(text="Add new")[0]
d(text="Add new")[1]
...

# iterator
for view in d(text="Add new"):
    view.info  # ...

Notes: when you are using selector like a list, you must make sure the screen keep unchanged, else you may get ui not found error.

Get the selected ui object status and its information

Check if the specific ui object exists

d(text="Settings").exists # True if exists, else False
d.exists(text="Settings") # alias of above property.

Retrieve the info of the specific ui object

Below is a possible result:

{ u'contentDescription': u'',
  u'checked': False,
  u'scrollable': False,
  u'text': u'Settings',
  u'packageName': u'com.android.launcher',
  u'selected': False,
  u'enabled': True,
  u'bounds': {u'top': 385,
              u'right': 360,
              u'bottom': 585,
              u'left': 200},
  u'className': u'android.widget.TextView',
  u'focused': False,
  u'focusable': True,
  u'clickable': True,
  u'chileCount': 0,
  u'longClickable': True,
  u'visibleBounds': {u'top': 385,
                     u'right': 360,
                     u'bottom': 585,
                     u'left': 200},
  u'checkable': False
}

Set/Clear text of editable field

d(text="Settings").clear_text()  # clear the text
d(text="Settings").set_text("My text...")  # set the text

Perform the click action on the seleted ui object

Perform click on the specific ui object

# click on the center of the specific ui object
d(text="Settings").click()
# click on the bottomright corner of the specific ui object
d(text="Settings").click.bottomright()
# click on the topleft corner of the specific ui object
d(text="Settings").click.topleft()
# click and wait until the new window update
d(text="Settings").click.wait()

Perform long click on the specific ui object

# long click on the center of the specific ui object
d(text="Settings").long_click()
# long click on the bottomright corner of the specific ui object
d(text="Settings").long_click.bottomright()
# long click on the topleft corner of the specific ui object
d(text="Settings").long_click.topleft()

Gesture action for the specific ui object

Drag the ui object to another point or ui object

# notes : drag can not be set until Android 4.3.
# drag the ui object to point (x, y)
d(text="Settings").drag.to(x, y, steps=100)
# drag the ui object to another ui object(center)
d(text="Settings").drag.to(text="Clock", steps=50)

Swipe from the center of the ui object to its edge

Swipe supports 4 directions:

left
right
top
bottom

d(text="Settings").swipe.right()
d(text="Settings").swipe.left(steps=10)
d(text="Settings").swipe.up(steps=10)
d(text="Settings").swipe.down()

Two point gesture from one point to another

d(text="Settings").gesture((sx1, sy1), (sx2, sy2)) \
                  .to((ex1, ey1), (ex2, ey2))

Two point gesture on the specific ui object

Supports two gestures:

In, from edge to center
Out, from center to edge

# notes : pinch can not be set until Android 4.3.
# from edge to center. here is "In" not "in"
d(text="Settings").pinch.In(percent=100, steps=10)
# from center to edge
d(text="Settings").pinch.Out()

3 point gesture

d().gestureM((sx1, sy1), (sx2, sy2),(sx3, sy3)) \
                  .to((ex1, ey1), (ex2, ey2),(ex3,ey3))
d().gestureM((100,200),(300,200),(600,200),(100,600),(300,600),(600,900))

Wait until the specific ui object appears or gone

# wait until the ui object appears
d(text="Settings").wait.exists(timeout=3000)
# wait until the ui object gone
d(text="Settings").wait.gone(timeout=1000)

Perform fling on the specific ui object(scrollable)

Possible properties:

horiz or vert
forward or backward or toBeginning or toEnd

# fling forward(default) vertically(default) 
d(scrollable=True).fling()
# fling forward horizentally
d(scrollable=True).fling.horiz.forward()
# fling backward vertically
d(scrollable=True).fling.vert.backward()
# fling to beginning horizentally
d(scrollable=True).fling.horiz.toBeginning(max_swipes=1000)
# fling to end vertically
d(scrollable=True).fling.toEnd()

Perform scroll on the specific ui object(scrollable)
