Question

I am planning to use monkeyrunner scripts to do automated test cases and I want to use robotframework(I am not interested in robotium).
I saw an excellent tutorial for automating sikuli scripts with robotframework at
http://blog.mykhailo.com/2011/02/how-to-sikuli-and-robot-framework.html

Is there any way to do similar thing, with robotframework and monkeyrunner?

Here is my sample monkeyrunner script,this executes correctly when invoked with monkeyrunner.

from __future__ import with_statement
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice

def testCase() :
    device = MonkeyRunner.waitForConnection()
    result2 = device.takeSnapshot()
    # Writes the screenshot to a file
    result2.writeToFile("scr.png","png")

def my_keyword():
    print 'Hello, world!'

if __name__ == '__main__':
    testCase()

I want to invoke the same with roboframework. and I am trying the following. I am not sure whether the following invocation is correct or not, I simply copied from sikuli automation example and modified it.

monkey_jar=/home/user/android-sdks/tools/lib/monkeyrunner.jar
guava_jar=/home/user/android-sdks/tools/lib/guavalib.jar
java -cp "robotframework-2.7.4.jar:$monkey_jar:$guava_jar" -Dpython.path="/home/user/android-sdks/tools/lib/" \
org.robotframework.RobotFramework --pythonpath=./  --outputdir=results --loglevel=TRACE $1

When I do this, I am getting the following error.

I believe that executing monkeyrunner test cases along with roboframework is quite possible.

Any inputs?

Well, after trying for few days, I found that it is possible to use MonkeyRunner scripts with Robotframework.

In short, you can use the folllowing to launch robotframework along with monkeyrunner.

export cpath=$(echo libs/*.jar | tr ' ' ':')
java   -Dpython.path=$cpath -jar robotframework-2.7.4.jar robo-tests.txt

But only problem was, monkeyrunner’s main was not called, thus not initializing the ChimpChat object, which results in a null pointer exception. I fixed that in MonkeyRunner.java, and created a new monkeyrunner.jar. With this, I am able to run monkeyrunner scripts from roboframework. I will try to create a step by step tutorial and post it.
