Parameters
----------
test_case
Object of type TestCase that should contain the relevant check functions.
nominal_input_name
String signifying the internal name of the input variable
(needed for error messages in case the check functions fail.)
nominal_input
Nominal value of the input variable.
zero_check
Optional boolean signifying whether or not to perform a check where a
zero value for the input variable is checked.
