After runningMUnit suite, it will provide test results, errors, failures (if any) and other details on the console in Anypoint Studio. mule. properties file, you'll have to pass the environment variable from Run Configurations. Global Variables, on the other hand are defined only within a dataweave script (because in mule context global variables do not exist).
