1、 Preface

At present, there are two main schemes for weak network special testing on mobile devices ：

1、 adopt Android The device is connected to PC Weak network test on , such as Fiddler,Charles,NET-Simulator etc. . The basic idea is PC Put one on top Fiddler Network packet capturing tool , And then Android Network agent of the device to PC On , By means of PC Upper Fiddler Set delay for weak network simulation .

2、 Building weak networks on proprietary servers WiFi, Mobile devices connect to this WiFi Conduct weak network test , Relevant technical solutions include Facebook Of ATC And Tencent WeTest-WiFi.

The idea of weak net test ：

1、 Weak network function test ：2G/3G/4G/5G、 High delay 、 High loss package

2、 No network state test ： Network disconnection function test 、 Local data storage

3、 User experience focuses on ： response time 、 Page rendering 、 Overtime copywriting 、 Over time reconnection 、 Safety and large flow risk

4、 Network switching test ：Wifi-2G/3G/4G/5G- No network multi state switching

User experience concerns ：

1、 Page response time is acceptable , Concerns include hot start 、 Cold start time 、 Page switching 、 Front and rear station switching 、 First time , First screen time, etc .

2、 Whether the page rendering is completed consistently .

3、 Whether the overtime copy meets the definition , Whether the abnormal information is displayed normally .

4、 Whether there is timeout reconnection .

5、 Safety angle ： Will it happen DNS hijacked 、 land IP Change frequently 、 Single sign on exception, etc .

6、 High traffic event risk ： Whether it will be updated under the weak network Apk package 、 Download files and other large traffic action .

2、 brief introduction

QNET Network testing tools can be used without the help of PC Or the server , Build a perfect weak network environment , Weak network simulation test , Just install... On any smartphone QNET Network testing tools , That is to complete the construction of weak network environment , Next, select different scenarios for testing as needed ; It also provides network packet capture function , Facilitate the analysis of network data problems .

characteristic ：

1、 Weak network construction is simple and fast . There is no need to build an additional weak network environment , There is no need to ROOT/ Cell phone for prison break , There's no need to connect data lines , Just install QNET App, Build a weak network test environment in one minute .

2、 Automated weak network testing .QNET Support adb Command driven , Users can write scripts , Implement automated weak network testing , Reduce the cost of weak network testing , Improve test efficiency .

3、 Network protocol packet capturing . There is no need to ROOT/ Cell phone for prison break , No need for third party tools , Support TCP/UDP/ICMP Protocol network packet capturing , export pcap File format , Support Wireshark Wait for tools to check .

4、 Real global network and weak network scenarios . Covering all provinces in China 、 Real time network data of operators in overseas mainstream countries and regions , Provide real subway 、 Weak network scenarios such as elevators .

3、 install

There is no need to ROOT/ Cell phone for prison break , There's no need to connect data lines , To be independent app The way , Provide users with shortcuts 、 reliable 、 Fully functional weak network simulation service .

According to the mobile operating system , Download the specified version , Can be installed .

4、 testing procedure

1、 open APP, Log in

2、 Authorized login succeeded

4.1、 Configure weak network template and parameters

First, add and edit the weak net template , Provide different network scenarios , And the network parameters can be adjusted according to the test requirements , Weak network template supports adding 、 Delete 、 modify 、 Query operation .

There are two ways to add a weak network template ：

1、 Top right corner of the page “ newly added ” Button , For custom templates .

2、“ Network scene ” page , For each template “ add to ” Button , Set templates for different scenes .

According to the test needs , Fill in the corresponding parameters in combination , Then save it .

As shown in the figure ： Custom template

4.2、 Select test products for testing

Add the specified weak net template to the workbench page , Then select all applications or one application , Click the start button to start the weak network test .

For example, turn on the network packet capturing function , After the weak network test , Automatically generated in the mobile phone pcap Format file imported to PC On , Use the network packet capture tool Wireshark Just open the analysis .

notes ：iOS Version only supports all applications

1、Android edition

As shown in the figure ：Android Version open weak network test

Setup page , Enabled ： Network packet capture 、 Control the suspended window 、 Information suspension window .

2、iOS edition

As shown in the figure ：iOS Version open weak network test

Setup page , Enabled ： Network packet capture

notes ：iOS There is no version control floating window 、 Information floating window function .

5、adb Command execution

adb The instruction execution function can automatically enable the weak network , Help users access weak networks for automated testing .

Before using , take Android And PC use USB Connect , And make sure it is connected .

1、 start-up

First execute the command to start QNET process ：

adb shell am start {--[ type ] [key] [value]} com.tencent.qnet/.Component.AdbStartActivity

Copy

Examples of use ： For wechat UDP The upside 20ms Delay packet capturing

adb shell am start --ei "dump_pcap" 1 --es "package_name" "com.tencent.mm" --ei "out_delay" 20 --ei "protocol" 2 com.tencent.qnet/.Component.AdbStartActivity

Copy

2、 to update

Update weak network parameters ：

adb shell am broadcast -a "qnet.boradcast.drive" --include-stopped-packages {--[ type ] [key] [value]} com.tencent.qnet

Copy

Examples of use ： Update parameters TCP/UDP 100% Packet loss

adb shell am broadcast -a "qnet.boradcast.drive" --include-stopped-packages --es "command" "update" --ei "in_rate" 100 --ei "out_rate" 100 --ei "protocol" 3 com.tencent.qnet

Copy

3、 end

End the weak network and exit the process ：

adb shell am broadcast -a "qnet.boradcast.drive" --include-stopped-packages {--[ type ] [key] [value]} com.tencent.qnet

Copy

Examples of use ： End weak network

adb shell am broadcast -a "qnet.boradcast.drive" --include-stopped-packages --es "command" "stop_service" com.tencent.qnet

Copy

4、 Parameter transfer mode

--[ type ] [key] [value]

--ei： Indicates that the parameter value is int

--es： Indicates that the parameter value is string
