How to use MonkeyDevice.instrument?

Question

HI guys, I'm trying to run one of my test instrumentation from my MonkeyRunner script. Unfortunately I can't get it to work. I've tried calling MonkeyDevice.instrument with different variations of the parameters but had no luck.

I've tried

device = MonkeyRunner.waitForConnection() device.instrument("android.test.InstrumentationTestRunner") device.instrument("com.myTestPackage.myTestClass") device.instrument("com.myTestPackage/.myTestClass") device.instrument("myTestClass")

None of these throw and error but they don't run the test either. I can run my instrumentation via Dev Tools or though Android Junit Test so I know it works.

So can someone tell me the correct to use this method? Thanks.

You are probably using wrong arguments. This script, which I named instrumentation.mr, helps you to use the right ones. Invoke it using you target package name.

#! /usr/bin/env monkeyrunner

import sys
from com.android.monkeyrunner import MonkeyRunner

PLI = 'pm list instrumentation'

def usage():
    print >>sys.stderr, "usage: intrumentation.mr target-package"
    sys.exit(1)

def main():
    if len(sys.argv) != 2:
        usage()

    pkg = sys.argv[1]

    print "waiting for connection..."
    device = MonkeyRunner.waitForConnection()

    print "running istrumentation for %s" % pkg
    for (i, t) in map(lambda l: l.split(), device.shell(PLI).splitlines()):
        if t == '(target=%s)' % pkg:
            print device.instrument(i.split(':')[1], { 'wait':True })['stream']
            return

    print >>sys.stderr, "ERROR: instrumentation for %s not found" % pkg

if __name__ == '__main__':
    main()

For example:

$ instrumentation.mr com.example.aatg.tc

prints:

waiting for connection...
running istrumentation for com.example.aatg.tc
