I am new to using unittest for testing my modules. Usually docstrings already contain a lot of useful info such as the datatypes expected by a function or the datatype of the return value. E.g.

def myFunc(parmA,paramB):
    """
    This function is awesome
    :param paramA: int
    :param paramB: str
    :return:
    """

Would there be a way to automatically test for raises TypeError when the wrong datatype is supplied, based on the information in the docstring?

Oh, you mean static type checking. – mkrieger1 Oct 11 '17 at 12:42

Go for [python type annotations](https://docs.python.org/3/library/typing.html), it has its own syntax for it. Then go for one of the tools as @mkrieger1 suggested. – uphill Oct 11 '17 at 13:06
