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

OK (31 tests)

The MonkeyDevice.instrument(string class, dictionary args) maps onto the InstrumentationTestRunner commands. The Android documentation has some good info on the instrumentation command, here.

What the documentation does NOT tell you is how to specify args. I found that in the android source code. See AdbChipDevice line 483. Here s a copy and paste of the code:

   482     @Override
   483     public Map<String, Object> instrument(String packageName, Map<String, Object> args) {
   484         List<String> shellCmd = Lists.newArrayList("am", "instrument", "-w", "-r");
   485         for (Entry<String, Object> entry: args.entrySet()) {
   486             final String key = entry.getKey();
   487             final Object value = entry.getValue();
   488             if (key != null && value != null) {
   489                 shellCmd.add("-e");
   490                 shellCmd.add(key);
   491                 shellCmd.add(value.toString());
   492             }
   493         }
   494         shellCmd.add(packageName);
   495         String result = shell(shellCmd.toArray(ZERO_LENGTH_STRING_ARRAY));
   496         return convertInstrumentResult(result);
   497     }

So the following python monkey code:

params = dict()
params[ size ] =  small 
device = MonkeyRunner.waitForConnection()
device.instrument( com.mycompany.myapp/android.test.InstrumentationTestRunner , params)

Is equivalent to the following command:

adb shell am instrument -w -r -e size small com.mycompany.myapp/android.test.InstrumentationTestRunner
