Android 测试学习笔记（三）

Android 测试 TDD 持续集成

管理测试环境

Headless emulator

$ emulator -avd testdevice -no-window -no-audio -no-boot-anim -port 5580

• port: 5554 ~ 5584

$ adb -s emulator-5580 install YourApp.apk
$ adb -s emulator-5580 shell am instrument -w\ 
com.blundell.tut.test/android.test.InstrumentationTestRunner
com.blundell.tut.test.MyTests:......
com.blundell.tut.test.MyOtherTests:..........
Test results for InstrumentationTestRunner=..................
Time: 15.295
OK (20 tests)

• unlock the screen
  第 1 种方式: $ adb -s emulator-5580 emu event send EV_KEY:KEY_MENU:1 EV_KEY:KEY_MENU:0
  第 2 种方式:

@Override
public void setUp() throws Exception    {
    Activity activity = getActivity();
    Window window = activity.getWindow();
    window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
}

• 清理，重启模拟器
  $ adb -s emulator-5580 shell 'stop; sleep 5; start'
$ emulator -avd testdevice -no-window -no-audio -no-boot-anim -port 5580 -wipe-data

• 终止模拟器
  $ adb -s emulator-5580 emu kill

• 其它例子

$ emulator -avd testdevice -no-window -no-audio -no-boot-anim -port 5580 -prop
persist.sys.language=ja -prop persist.sys.country=JP

模拟网络环境

For network speed:

Option	Description	Speeds [kbits/s]
-netspeed gsm	GSM/CSD	Up: 14.4, down: 14.4
-netspeed hscsd	HSCSD	Up: 14.4, down: 43.2
-netspeed	gprs GPRS	Up: 40.0, down: 80.0
-netspeed edge	EDGE/EGPRS	Up: 118.4, down: 236.8
-netspeed umts	UMTS/3G	Up: 128.0, down: 1920.0
-netspeed hsdpa	HSDPA	Up: 348.0, down: 14400.0
-netspeed full	No limit	Up: 0.0, down: 0.0
-netspeed	Select both the upload and download speed	Up: as specified, down: as specified
-netspeed :	Select the individual up and down speed	Up: as specified, down: as specified

For latency:

Option	Description	Delay [msec]
-netdelay gprs	GPRS	Min 150, max 550
-netdelay edge	EDGE/EGPRS	Min 80, max 400
-netdelay umts	UMTS/3G	Min 35, max 200
-netdelay none	No latency	Min 0, max 0
-netdelay	Select exact latency	Latency as specified
-netdelay :	Select min and max latencies	Minimum and maximum latencies as specified

$ emulator -avd testdevice -port 5580 -netspeed gsm -netdelay gprs

$ telnet localhost 5580
network status
Current network status:
    download speed:         14400 bits/s (1.8 KB/s)
    upload speed:           14400 bits/s (1.8 KB/s)
    minimum latency:    150 ms
    maximum latency:    550 ms
OK

加速模拟器

• SDK17 起不需要
• 从 Android SDK Manager 下载 HASM， 安装: kextstat | grep intel

运行 Monkey

命令行方式

$ adb -e shell monkey -p com.blundell.tut -v -v 1000
Events injected: 1000
:Sending rotation degree=0, persist=false
:Dropped: keys=0 pointers=4 trackballs=0 flips=0 rotations=0
## Network stats: elapsed time=2577ms (0ms mobile, 0ms wifi, 2577ms not connected)
// Monkey finished

客户/服务器方式

$ adb -e shell monkey -p com.blundell.tut --port 1080 &
$ adb -e forward tcp:1080 tcp:1080
$ telnet localhost 1080
tap 150 200

• monkey 脚本示例

# monkey
tap 200 200         # Touch and select the edit text input
type HelloWorld     # Type Hello World
tap 200 350         # Tap the button to show the toast
tap 200 200         # Touch and select the edit text again
press DEL           # delete the text
press DEL
press DEL
press DEL
press DEL
type Monkey         # Type Monkey
tap 200 350         # Tap the button to show the toast Hello Monkey

$ adb shell am start -n com.blundell.tut/.MonkeyActivity
$ nc localhost 1080 < ch_4_code_ex_10.txt

使用 monkeyrunner

• Monkeyrunner is built on top of Jython

示例（Getting test screenshots）

#! /usr/bin/env monkeyrunner
import sys
# Imports the monkeyrunner modules used by this program from com.android.monkeyrunner   
# import MonkeyRunner, MonkeyDevice, MonkeyImage
# Connects to the current device, returning a MonkeyDevice object
device = MonkeyRunner.waitForConnection()
if not device:
    print >> sys.stderr, "Couldn't" "get connection"
    sys.exit(1)
device.startActivity(component='com'.blundell.tut/.MonkeyActivity')
MonkeyRunner.sleep(3.0)
device.type("hello")
# Takes a screenshot
MonkeyRunner.sleep(3.0)
result = device.takeSnapshot()
# Writes the screenshot to a file
result.writeToFile('/tmp/device.png')
device.press('KEYCODE_BACK', 'DOWN'_AND_UP')

录制和回放

• The monkey_recorder.py script, which is included in the Android source repository in the SDK project, can be used to record event descriptions that are later interpreted by another script called monkey_playback.py.
  
• 一旦操作完毕，保存脚本文件（script.mr）后，下次即可快速重复运行: $ monkey_playback.py script.mr
