# When used within the test, you control various aspects with environment
# variables or functions.
#
# - The content passed into mo is either the variable "$template" or the output
#   of the function called template.
# - The expected result is either "$expected" or the function called expected.
# - The expected return code is "$returnCode" and defaults to 0.
# - The arguments to pass to mo is the array "${arguments[@]}" and defaults to ().
#
# When $MO_DEBUG is set to a non-empty value, the test does not run, but mo is
# simply executed directly. This allows for calling mo in the same manner as
# the test but does not buffer output nor expect the output to match the
# expected.
#
# When $MO_DEBUG_TEST is set to a non-empty value, the expected and actual
# results are shown using "declare -p" to provide an easier time seeing the
# differences, especially with whitespace.
