Chapter IX app project test (2) test tools

9.4 APP Testing tools

Because the limitations of mobile phones bring a lot of inconvenience to the test , So in APP Test relative Web Testing is more concerned with the use of some tools , Introduce to you Android Use of mobile phone test tools .

Android Main directory description of the system , As shown in the table 9-1

9.4.1   ADB Tool is introduced

ADB(Android Debug Bridge Abbreviation ） yes Android SDK There is a multi-purpose debugging tool , Can pass ADB To manage the state of the device or emulator .ADB Tools by 3 Components ;

1） Client running on the computer .PC The client mainly communicates with the simulator or device through the client .

2） A server that runs as a background process on a computer . Responsible for managing client and emulator or on device adbd Interprocess communication .

3） Daemon adb Run on the simulator or device in the form of a background process .

When a ADB client , The client first confirms whether there is a ADB The server process is running . If there is no process , Then start the server process . When ADB Server running , Will be bound to the local TCP port 5037, And monitor ADB Command from client . The server then connects all running emulators or device instances . It will scan all 5554~5584 To locate all emulators or devices . Once the server is connected to all simulator instances , have access to ADB Commands control and access the device . General format for sending commands ：adb-s Device command （ Through the command adb devices Get the device name ）

Use ADB It can mainly complete the following functions ：

1） It can quickly update the software on the device or simulator ;

2） Can run on a device or simulator shell command

3） You can synchronize files on your device or emulator 、 Upload 、 Download the file ;

4） It can be captured in real time APP Runtime Log Information .

2、ADB Tool installation process （ skip ）

3、ADB Basic command Introduction

（6） adb logcat

adb logcat: For grabbing log Track information Bug track . The command format is as follows ：

 adb logcat[option][filter-spec]

logcat See table for command options 9-2, The usage is as follows ：

 adb logcat, It means to capture the whole mobile phone in real time log Information and enter information in the command prompt window .

adb logcat>D:\log.txt, Will be captured in real time log Information and save it locally log.txt file .

adb logcat-v time>D:\log.txt, Acquired log.txt Add time information to the file .

adb logcat-b radio>D:\log.txt, Obtain network RF information .

adb logcat-b events>D:\log.txt, Get event messages

adb logcat-v time-b main-b radio-b system>logcat.txt Commonly used , obtain log Information plus time information , It mainly displays the buffer and the logs related to the phone and system .

logcat See table for command filtering 9-3

  Besides adb logcat It can be used to filter and set filter content , You can also filter content in conjunction with matching regular expressions .

notes ： When the application or system is rebooted or crashed abnormally, it grabs log

 adb bugreport obtain bugreport Information .bugreport Record android Of the startup process  log, And the state of the system after startup , Include a list of processes 、 Memory information 、VM Information, etc .

adb shell dumpsys dropbox-print obtain dropbox Information . Record the occurrence of exceptions and other information , Used to analyze crash、 Restart, etc. .

adb pull/data/anr/ obtain anr Information , Grab the information file when the system or application responds .

（7）adb shell

Provides shell terminal , adopt shell The terminal can run various commands on the simulator or equipment , These orders are linux shell A subset of . Can pass adb shell Command to use these commands , such as ：adb shell ls,, You can also use the command first ：adb shell Access to the device or simulator shell terminal , Then use the corresponding command . When the device is shell State, , It can be used exit To quit shell terminal .
