# diningHours_test: tests the dining hours plugin.
# 
# Test the dining hour plugin for obtaining local system time
# and compare to two test times for recognize in/off hours.
# Does not require any additional commands to be implemented
# or otherwise unsable.
#
# Because local system times vary depending on time of testing,
# we cannot verify full functionality of plugin. Two test ids 
# were created (testopen and testclosed) to test if plugin can
# obtain the local system time and recognizes that testopen
# is opened and testclosed is closed regardless of time.
