Monkey test of APP automation

One 、 Why do it monkey test

background ： With the rise of mobile Internet , More and more APP Into our lives , Such as WeChat 、 Tiktok 、 Taobao, etc. , These are commonly used APP Generally, there are a large number of users 、 Long online time , Such as daily activity of Tiktok 8 Billion , Online time average 3 Start in an hour , So I'm testing APP In the process of , In addition to considering the accuracy of the function , Compatibility, etc , It needs to be taken into account APP The stability of . On the market , It is generally used monkey Tools to test Android APP The stability of ,iOS The stability of is generally provided by the open source community iOSmonkey To test the stability .

monkey Test node time ： APP Basically stable function , Before pre release and acceptance

Commonly used tools ：monkey 、Python 、git、gitlab、Jenkins

Two 、 What is? monkey test

monkey test Android A means of automation ,monkey It's very simple , It is to use scripts to simulate a series of common user operations , Such as setting screen brightness 、 Adjust sound 、 slide 、 Gesture input, etc , The whole process is pseudo-random , Randomness is reflected in the randomness of actions , Pseudo representations can be passed through -s namely seed value To reproduce the last operation .

3、 ... and 、monkey Test environment preparation

One 、 Environmental preparation

install jdk1.8, To add to path
install Android SDK , To add to path

Verify that the environment is installed successfully ：
jdk ：

SDK：

If as above , Display the corresponding version number SDK and jdk Installation successful

Two 、 Connecting device

mobile phone ：

1. Connect your phone with a data cable
2. Turn on the mobile developer mode , open USB Debugging function
3. stay DOS Window type adb devices , If the equipment number appears , The connection is successful

Simulator ：

1. Turn on the simulator
2. DOS Window input command ：adb connect IP:port, Such as adb connect 127.0.0.1:7555
3. stay DOS Window type adb devices , If the equipment number appears , The connection is successful

Take the simulator for example ：

PS： If you don't know the simulator port, you can check it on the official website , After the real machine is connected , Direct use adb devices that will do

Four 、monkey How to test

One 、monkey Common commands

see monkey Parameters adb shell monkey

C:\Users\zyd>adb shell monkey

              [--device-sleep-time MILLISEC]
              [--randomize-script]
              [--script-log]
              [--bugreport]
              [--periodic-bugreport]
              [--permission-target-system]
              COUNT


C:\Users\zyd>

Carry out... On the whole machine 200 Event operation ：adb shell monkey 200

- p Specify the application package name ：adb shvell monkey -p com.xueqiu.android 1000

- ignore-crashes ： Ignore the crash

While the script is running , In general, you will encounter a crash ,monkey It will end , Plus ignore parameters , You can make the script run normally , And record the time of the crash and the detailed reason .

- ignore-timeouts： Ignore timeout

Ignore problems that should be caused by timeouts during scripting

- ignore-security-exceptions ： Ignore security certificate issues

Ignore problems that should be caused by security certificate problems in the script process

- v Specify the log level ：adb shell monkey -p com.xueqiu.android -v 1000

The minimum level is -v

The highest level is -v -v -v

Due to the large number of logs , Generally, redirection is used to output log information

- s Appoint seed value ：adb shell monkey -p com.xueqiu.android -s 1235 1000

seed Values are also called sequence values , Or seed value , Often used to reproduce problems , Fruit twice seed equally , Then it means that the sequence of actions simulated by the script is the same , But there is no guarantee that the objects of the operation are the same .

-throttle MILLISEC Delay time

Time between events , Work is generally 450ms

Number of events at work ：30w Time , Delay time ：450ms , Script execution time 8-10 Hours

5、 ... and 、 Result analysis ：

// Monkey finished Express monkey End of test

Common causes of failure ：

View the logs by keyword search bug

1.crash Run away

crash Submit bug when , add to logcat Just log .

2.ANR No response

ANR Submit bug when ,adb shell 、data/anr/traces.txt, Need to submit traces.txt file .

monkey Abnormal interruption

• Abnormal shutdown of mobile phone
• The phone restarts abnormally
• mobile phone CPU Abnormal temperature, etc

bug Submit

title ：【monkey】【crash/ restart /…】APP In execution monkey Test occurrence crash/ restart /…

Repeat step ：

1. Environmental Science
2. command
3. View results

Expected results ： monkey Execution without exception
The actual result ： monkey In the process of execution crash

By keyword analysis logcat journal , Such as ANR/fatal/reboot/OOM/exception

#  Redirect download logcat journal 
adb logcat -v time >E:\APPLOG\logcat.txt

adb shell monkey -p com.xueqiu.android - 300

6、 ... and 、 complete monkey Script ：

adb shell monkey --throttle 450 --ignore-security-exceptions --ignore-crashes --ignore-timeouts -v -v -v -p com.xueqiu.android 200 >E:\APPLOG\logcat.txt

logcat The documents are as follows ：
