"""Test if a function or method can be called or initialised correctly with
different values for their input arguments (parameters).
The argument 'test_data' must be a dictionary with the following
structure:
- Keys are tuples consisting of three strings:
(module_name, class_name, function_or_method_name)
- Values are dictionaries where the keys are the names of the input
argument that is being tested, and the values of these dictionaries
are a list that contains two lists. The first list contains valid
input arguments ('normal' argument tests) that should pass the test,
while the second list contains illegal input arguments ('exception'
argument tests) that should raise an exception.
The lists of test cases are itself lists, each containing a number of
input argument values, as many as are expected by the function or
method that is being tested.
This function returns a list containing the test results, where each
list element is a string with comma separated values (CSV) which are to
be written into the testing log file.
