# Test script is organized like this:
#   o two variables (PASSED and FAILED) hold the total 
#     number of passed/faled tests
#   o expect() function performs a single test. First 
#     argument of the function is the variable name and
#     the second is an expected value. PASSED/FAILED
#     values are updated automatically
#
# Most tests look like:
#     |
#     | expect "varName" "expectedValue" << JSON_END
#     | ..json data here...
#     | JSON_END
#     |
