added test case for defect MAGN3113 with function RunCommandFromFile() 

function RunCommandFromFile() is used to run the xml file
Defect: http://adsk-oss.myjetbrains.com/youtrack/issue/MAGN-3113
@Randy-Ma Please help me to review it

I have not seen the usage of commandCallback since the only case used here, we are using the default null value.
