Reinstall the path name of Install-rapk and keep the original cache
The package name of Adbuninstallapk eg: adbuninstallcom.baidu.searchbox
How to get the package name:
adbshellpmlistpackages get package name
adbshellpmlistpackages-3 Get third-party package name
adbshellpmlistpackages-s system package name
adbshelldumpsysactivityactivitiesadb command to get the current interface Activity
The execution result is: com.baidu.searchbox/.MainActivityt3
adbshelldumpsyscpuinfo to view the CPU usage on the mobile phone
adbshellgetprop|findstrdalvik view the memory usage of the machine (all apps)
adbshelldumpsysmeminfo+package name to view the memory usage of specific apk
adblocat comes and goes to get logs
adblogcat-c clear log
Adblogcat*: W corresponds to printing logs containing W and above
adb-s device name logcat-vtimeprocess>C:/log/aa.txt
Specify one device among multiple devices and print the v-level log and time, and put the log results under the c drive
Android logs are divided into the following levels:
V-Verbose (lowest, most output)
D——Debug
I —— Info
W——Warning
And —— Error
F——Fatal
S-Silent (the highest, nothing is output)
Monkey commonly used commands
Level 0: adb shell monkey -p com.example.login -v 100 // The default value, only provides a small amount of information such as startup prompt, test completion and final result
Level 1: adb shell monkey -p com.example.login -v -v 100 // Provide a more detailed log, including every event information sent to Activity
Level 2: adb shell monkey -p com.example.login -v -v -v 100 // The most detailed log, including selected/unselected activity information in the test
Used to specify the seed value of the pseudo-random number generator. If the seed is the same, the sequence of events generated by the two Monkey tests is also the same. Example:
monkey测试1：adb shell monkey -p com.shjt.map –s 10 100
monkey测试2：adb shell monkey -p com.shjt.map –s 10 100
adb shell monkey -p com.example.login --ignore-crashes --ignore-timeouts --throttle 100 --pct-touch 50 --pct-motion 50 -v -v 1000 >c:\login\c.txt

In the interview season of the Golden 9th and the Silver 10th, the job-hopping season, organizing interview questions has become my habit for many years! The following is my collection and sorting in recent years, the whole is organized around [software testing], the main content includes: python automation test exclusive video, Python automation details, a full set of interview questions and other knowledge content.
For software testing friends, it should be the most comprehensive and complete interview preparation warehouse. In order to better organize each module, I also refer to many high-quality blog posts and projects on the Internet, and strive not to miss every knowledge point. Friends relied on these contents to review and got offers from big factories such as BATJ. This warehouse has also helped many learners of software testing, and I hope it can help you too!
May you and I meet and you will find something! Welcome to follow the WeChat public account: [Sad Spicy Article] Receive a 216-page software test engineer interview book for free. And the corresponding video learning tutorials are free to share!
