Unit tests raising Error. (#2)

* fixed assertAlmostEqual calls in tests

As you can see in the docs the signature of assertAlmostEqual is `assertAlmostEqual(first, second, places=7, msg=None, delta=None)`
Since the message is originally provided using a positional argument and only three arguments where given, the message effectively took the place of the `places` argument.

The default of places=7 is fine, we just have to use a keyword argument instead and this will resolve the resulting `TypeError`s when testing

* change assertAlmostEqual to assertEqual for string

assertAlmostEqual only makes sense when asserting ints/floats

* no need for keyword argument

Signature of method is `assertEqual(first, second, msg=None)`
Using a keyword argument is not required here.
