As a novice in the testing industry, it is necessary for Xiaobai to understand some Monkey tests. In this small compilation, we have sorted out the basis of Monkey tests in App and the compilation of Monkey scripts. I hope it can help you.

1. Monkey concept

Monkey test, also known as "monkey test", means that people without testing experience randomly click on the product. Monkey is a command-line tool of Android system. It can send pseudo-random user event flow (such as keys, touch screen, gestures, etc.) to the tested application to test the application. Monkey is usually used for stress test and stability test.

When is it appropriate to use monkey test?

A: generally, the product is relatively stable. When there are not many bug s, monkey is usually used to test the stability and robustness of the application to be tested (whether flash back, crash and ANR problems will occur)

2. Use monkey

The first part introduces the basic concept of Monkey, so how to use Monkey for testing Xiaobai?
Step 1: you need to install the adb tool on your computer. If you don't know how to install it, you can refer to another blog in Xiaobian Introduction to ADB command
Step 2: find a real machine or simulator. You'd better use the real machine directly. It's more convenient. You need to turn on the USB debugging mode on the mobile phone and connect the computer with the data cable.
Step 3: open the command line and enter the command:
adb shell monkey
perhaps
adb shell monkey --help
After that, you will see a lot of contents in the command line. The following contents are Monkey's help information, mainly the use of parameters in Monkey tool

2.1 use of monkey parameter

First, let's take a look at the event parameter table, which contains some common parameters. Next, let's pick some to introduce the basic usage

1. -p
   Refers to the package that specifies the application to be operated, that is, the apk package.

   adb shell monkey -p packagename 1000
   -p Parameter specifies the package to run,
   1000 Indicates the number of events
    When multiple packages exist
   adb shell monkey -p packagename1 -p packagename2 1000
   

2. -s
   Random seed is a highly recommended method in the process of testing. If an exception occurs during the first run, you can reproduce the previous exception through random seed,

   adb shell monkey -p packagename -s 10 1000
   

3. -v
   You can view the process performed by monkey through - v. The Monkey log is divided into three levels: 0, 1 and 2, which correspond to a - v, - v -v and - v -v; If nothing is written in the monkey command, it defaults to level 0.

   0 Level: adb shell monkey -p packagename -v 1000
   1 Level: adb shell monkey -p packagename -v -v 1000
   2 Level: adb shell monkey -p packagename -v -v -v 1000		
   

   Specific case analysis:
   Enter the command: ADB shell monkey - P packagename - V - V 1000
   A lot of contents will be output in the command window, and a section is intercepted below:

   ~ ~ adb shell monkey -p com.qiniu.pili.droid.shortvideo.demo -v -v -v 100
   
     bash arg: -p
     bash arg: com.qiniu.pili.droid.shortvideo.demo

     bash arg: -v
     bash arg: -v
     bash arg: 100
   args: [-p, com.qiniu.pili.droid.shortvideo.demo, -v, -v, -v, 100]
    arg: "-p"
    arg: "com.qiniu.pili.droid.shortvideo.demo"
    arg: "-v"
    arg: "-v"
    arg: "-v"
    arg: "100"

   Next, analyze the above logs

   :Monkey: seed=1633995691825 count=100
   Monkey When using pseudo-random numbers seed When generating an event sequence, the system will randomly assign a value when no random seed is specified, count Indicates the number of random events
   
   :AllowPackage: com.qiniu.pili.droid.shortvideo.demo
    Indicates start only com.qiniu.pili.droid.shortvideo.demo In package Activity. 
   
   :IncludeCategory: android.intent.category.LAUNCHER
   :IncludeCategory: android.intent.category.MONKEY
    Indicates the intention to start. The weight is " LAUNCHER"And " MONKEY"Activities.
   
   // Event percentages:
   //   0: 15.0%
   //   1: 10.0%
   //   2: 2.0%
   //   3: 15.0%

   //   9: 2.0%
   //   10: 1.0%
   //   11: 13.0%
   The proportion of various types of events in this pseudo-random event, such as key press, sliding screen and other events, can also set corresponding parameters
   :Switch: #Intent;action=android.intent.action.MAIN;category=android.intent.category.LAUNCHER;launchFlags=0x10200000;component=com.qiniu.pili.droid.shortvideo.demo/.activity.MainActivity;end
    Indicates jump to“ com.qiniu.pili.droid.shortvideo.demo"In package“.activity.MainActivity"This activity.
   
   
   // Allowing start of Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.qiniu.pili.droid.shortvideo.demo/.activity.MainActivity } in package com.qiniu.pili.droid.shortvideo.demo
    Indicates that startup is allowed“ com.qiniu.pili.droid.shortvideo.demo"In package“.activity.MainActivity"This activity.
   
   Sleeping for 0 milliseconds
    express Monkey A delay is allowed when sending various random events, because we did not specify it on the command line Monkey Event messages can only be sent as quickly as possible.
   
   Events injected: 100
    The above information indicates that 100 injection events have been generated because it is set to 100 on the command line
   
   :Sending rotation degree=0, persist=false
    Indicates that the screen rotates. The rotation angle is 0. Whether to keep the rotation state is false.
   
   :Dropped: keys=0 pointers=0 trackballs=0 flips=1 rotations=0
    Indicates the discarded screen rotation related information. Discard: key=0，Pointer=0，track ball=0，Keyboard flick=1，screen flipping=0.
   // Monkey finished
    If you see this sentence in the log, it means that the execution is successful. There is no problem in this process.
   

4. Log save

   adb shell monkey -p com.qiniu.pili.droid.shortvideo.demo -v -v -v 100 >/Users/Downloads/monkey.log
   

5. Comprehensive case display
   We know what the parameters in Monkey mean and how to use them. Next, we will show you a comprehensive case:

   adb shell monkey -v -v -v --ignore-crashes --ignore-timeouts --kill-process-after-error --ignore-security-exceptions -p com.qiniu.pili.droid.shortvideo.demo -s 100 --pct-touch 50 --throttle 3000 1000
    Relevant security, timeout, crash and other exceptions are ignored during the test
   --pct-touch 50 Touch screen events are 50%
   --throttle 3000 The event interval is 3 seconds
   -s 100 The seed is 100
   

3. Monkey script

First, let's show you the Monkey script. The name of the script is monkey.txt. The content is as follows:
For the coordinate problem in tap (960274), we can use the uiautomatorviewer tool to solve it. Of course, the simplest way is to set the mobile phone - Developer mode - pointer position, so that we can obtain the coordinates of the button.

type = raw events # Represents the type of script
count = 1 # It is used to describe the number of times of execution, but no matter what is changed, it is only executed once??
speed = 1.0 # Used to adjust the sending frequency of two random events.
start data >> # Start or start data & gt; & gt;

LaunchActivity(com.qiniu.pili.droid.shortvideo.demo) # Package name, interface name
Tap(960,274) ## button coordinates (click)
UserWait(5000) # waiting time
Tap(390,1538)
UserWait(13000)
Tap(780,1583)
UserWait(5000)
Tap(777,1183)
UserWait(5000)
Tap(30,1335)
UserWait(5000)
Tap(30,1456)
UserWait(5000)
Tap(945,81)
UserWait(5000)
DispatchPress(KEYCODE_BACK) # Click the back button

Step 1: write a monkey script and save it as monkey.txt (any name)
Step 2: Push the script to a file on the phone

adb push monkey.txt  /sdcard/

Step 3: run the script

adb shell monkey -f /sdcard/monkey.txt -v -v 1

The above is all about Monkey. I hope it can help you.
