Android Debug Bridge(adb)

advertisement
1. A tool helps us mange the state of an emulator instance
or Android-powered device
2. It is client-sever program that include three comopnents:
1). A client ,which runs on your development
machine.
2). A sever,which runs as a background process
on you development machine
3).A daemon ,which runs as a backgroud process
on each emulator or device instance
Clinet——Server
1.
Clinet first checks whether there is an adb server process
already running If there is not ,it start the server process.(all
adb clinet use port 5037 to communicate with the adb sever)
2.
The server then sets up connetion to all running
emulator/device instance . An even-numbered port for
console connections and an odd-numbered port for adb
connections

UI/Application Exerciser Monkey
1.The Monkey is a program that runs on your
emulator or device and generates pseudorandom streams of user events such as
clicks, touches, or gestures, as well as a
number of system-level events.
2. You can use the Monkey to stress-test
applications that you are developing,in a
random yet repeatable manner.
Four options
Basic configuration options, such as setting the
number of events to attempt.
 Operational constraints, such as restricting the
test to a single package.
 Event types and frequencies.
 Debugging options

Three conditions
If you have constrained the Monkey to run
in one or more specific packages, it
watches for attempts to navigate to any
other packages, and blocks them.
 If your application crashes or receives any
sort of unhandled exception, the Monkey
will stop and report the error.
 If your application generates an application
not responding error, the Monkey will stop
and report the error.

Basic Use of Monkey
Launch the Monkey using a command line
on your development machine or from a
script
The basic syntax is
a more typical command line
