This link

names method from Capital letter. At the same time method name (according to help(unittest) ) is skipTest (starting lowercase). For those who reads documentation online this mistype leads to error.

I think you'll find that your link points to the exception class `SkipTest`, which does start with a capital level.

This is distinct from the `skipTest` method of `unittest.TestCase` objects, which starts with a lowercase letter.

The documentation looks right to me. See [1] for a demonstration of the difference.
