Below is a simple unit test. What I am trying to do is set some values in the
context on creation of the task in the start state. The event is firing and my
action "SetupSuspiciousTransaction" is being run. This action sets variables
in the context. Later on I try to retrieve the variables and there values in
the method "retrieveVariables". When I step through this method "mappedName"
has the right variable name but "value" has null as the value. I was expecting
to get back the values I had put in earlier.
