Is "Monkey Runner" useful for testers to prepare test cases directly in Android applications?

I have gone through the "Monkey Runner" for the following link http://developer.android.com/guide/topics/testing/testing_android.html It has so much Java code. I am not able to under stand the code to create test cases. Is it only for developers, or the testers to test the application thoroughly. Is there any other pat开发者_如何学编程tern for creating test cases through code? Can any one suggest me about the same.

Thank you.

Have a look at my MonkeyRunner code. Should be easier then Java. Change path to save file, and replace phone number. I had only 1 problem. Cant Hangup a call.

I have learned monkeyrunner via this small guide. http://antoine-merle.com/introduction-to-the-monkey-runner-tool-2/

You do not have to use java, but to start low on python. For the ide you can use pycharm, which will give you a better start when creating classes in python.

As of the code which @Boris_Ivanov showed, this is a good start, but I would delete the "MonkeyImage" - as you are not using it also pushing the test cases into different files would add to speed if required to use.

One thing to talk about:

    Connect to the current device returning the MonkeyDevice object
    device = MonkeyRunner.waitForConnection()
    #MonkeyRunner.alert("Starting Activity", "monkeyrunner", "OK")

I am using something like this and it does work all the way:

    device = MonkeyRunner.waitForConnection(60)
    if not device:
        raise Exception('Can not connect to device')

Best luck.
