Description changed by daniellee:

Old description:

> wormholetesting.py seems to throw a lot of errors when using mypy
> --strict. I think this is a good place to start type annotations as it
> not related to that many other files.

New description:

 Using mypy with the `--strict` flag to type annotate file I encountered a
 candidate for refactoring in this file and I thought it might be a good
 place to start. There is not much to type annotate.

 `_verify()` function uses a deprecated function `getargspec()`. We aim to
 update this function to use the new `getfullargspec()` and yet maintain
 the strictness of the check.
