# Tests the functionality of timer plugin
#
# Written for CS 3214 Spring 2015.
#
# To run this test on your own shell, simply run:
# /web/courses/cs3214/spring2015/projects/student-plugins/dpho_rtm8889/timer/timer_test.py eshoutput.py
# from the directory in which your "esh", "plugins/"  and your "eshoutput.py" is located.
# 
# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
# !!!!!! timer.so should be in your plugins directory !!!!!!
