There was a problem hiding this comment.
the test will pass if the workflow is changed in either of the following ways:
startActivityinstead ofexecuteActivitynewStateVar&setSignalHandlerinstalled before the activity is dispatched
'signalWithStart' fails when the first thing executed is an Activity that is scheduled, takes some amount of time to finish executing, and is awaited _before_ the signal handler is installed.
