Purpose

UIAutomator is a great tool to perform Android UI testing, but to do it, you have to write java code, compile it, install the jar, and run. It's a complex steps for all testers...

This project is to build a light weight jsonrpc server in Android device, so that we can just write PC side script to write UIAutomator tests.

Build

• Run command:

$ ./gradlew build
$ ./gradlew packageDebugAndroidTest

• Run the jsonrpc server on Android device

$ ./gradlew cC
$ adb forward tcp:9008 tcp:9008 # tcp forward

If debug apk already installed, There is no need to use gradle.

simply run the following command

adb forward tcp:9008 tcp:9008
adb shell am instrument -w -r -e debug false -e class com.github.uiautomator.stub.Stub \
    com.github.uiautomator.test/androidx.test.runner.AndroidJUnitRunner

Run

$ curl -X POST -d '{"jsonrpc": "2.0", "id": "1f0f2655716023254ed2b57ba4198815", "method": "deviceInfo", "params": {}}' 'http://127.0.0.1:9008/jsonrpc/0'

The buildin input method

com.github.uiautomator/.AdbKeyboard

Encode the text into UTF-8 and then Base64

For example:

"Hello 你好" -> (UTF-8 && Base64) = SGVsbG8g5L2g5aW9

Send to AdbKeyboard with broadcast

Broadcast completed: result=-1 means success

# show ime list
$ adb shell ime list -s -a
com.google.android.inputmethod.latin/com.android.inputmethod.latin.LatinIME
com.google.android.tts/com.google.android.apps.speech.tts.googletts.settings.asr.voiceime.VoiceInputMethodService
com.github.uiautomator/.AdbKeyboard

# enable and set ime
$ adb shell ime enable com.github.uiautomator/.AdbKeyboard
$ adb shell settings put secure default_input_method com.github.uiautomator/.AdbKeyboard

# Append text to input field
$ adb shell am broadcast -a ADB_KEYBOARD_INPUT_TEXT --es text SGVsbG8g5L2g5aW9
Broadcasting: Intent { act=ADB_KEYBOARD_INPUT_TEXT flg=0x400000 (has extras) }
Broadcast completed: result=-1

# Clear text
$ adb shell am broadcast -a ADB_KEYBOARD_CLEAR_TEXT
Broadcasting: Intent { act=ADB_KEYBOARD_CLEAR_TEXT flg=0x400000 }
Broadcast completed: result=-1

# Clear text before append text
$ adb shell am broadcast -a ADB_KEYBOARD_SET_TEXT --es text SGVsbG8g5L2g5aW9
Broadcasting: Intent { act=ADB_KEYBOARD_SET_TEXT flg=0x400000 (has extras) }
Broadcast completed: result=-1

# Send Keycode or Editor code according to the InputEditor requires
$ adb shell am broadcast -a ADB_KEYBOARD_SMART_ENTER
Broadcasting: Intent { act=ADB_KEYBOARD_SMART_ENTER flg=0x400000 }
Broadcast completed: result=-1

# Send keycode, eg: ENTER
$ adb shell am broadcast -a ADB_KEYBOARD_INPUT_KEYCODE --ei code 66
# Send Editor code, eg: 2
$ adb shell am broadcast -a ADB_KEYBOARD_EDITOR_CODE --ei code 2 # IME_ACTION_GO

# Get clipboard (without data)
$ adb shell am broadcast -a ADB_KEYBOARD_GET_CLIPBOARD
Broadcasting: Intent { act=ADB_GET_CLIPBOARD flg=0x400000 }
Broadcast completed: result=0

# Get clipboard (with data, base64 encoded)
$ adb shell am broadcast -a ADB_GET_KEYBOARD_CLIPBOARD
Broadcasting: Intent { act=ADB_GET_CLIPBOARD flg=0x400000 }
Broadcast completed: result=-1, data="5LqG6Kej5Lyg57uf5paH5YyW"

# show keyboard
$ adb shell am broadcast -a ADB_KEYBOARD_SHOW
# hide keyboard
$ adb shell am broadcast -a ADB_KEYBOARD_HIDE

Change GPS mock location

You can change mock location from terminal using adb in order to test GPS on real devices.

adb [-s <specific device>] shell am broadcast -a send.mock [-e lat <latitude>] [-e lon <longitude>]
        [-e alt <altitude>] [-e accurate <accurate>]

For example:

adb  shell am broadcast -a send.mock -e lat 15.3 -e lon 99

Show toast

adb shell am start -n com.github.uiautomator/.ToastActivity -e message hello

Float window

adb shell am start -n com.github.uiautomator/.ToastActivity -e showFloatWindow true # show
adb shell am start -n com.github.uiautomator/.ToastActivity -e showFloatWindow false # hide

How to use with Python

import uiautomator2 as u2

d = u2.connect()

d.screen.on()
d(text="Settings").click()
d(scrollable=True).scroll.vert.forward()

Refer to python wrapper library uiautomator.
