docstrings as a note

**Is your feature request related to a problem? Please describe.**
This might be a thing in our team, but we *really* like docstrings. When a unit-test fails our current team relies on reliable docstrings to explain what is happening in a test. This is nice, because sometimes code is a language that is too cryptic to explain **why** a test is important

**Describe the solution you'd like**
I must admit that I'm just starting out with the project and there's parts that I love. I really enjoy the locals view in a failed test. But instead of notes, we might be interested in seeing the doctoring attached to the testing method. This might be a highly preferential thing on our team, but may just be worth considering.

**Describe alternatives you've considered**
Part of this problem could be explained with a note but a docstring feels like a more natural place to write a long part of text.

**Additional context**
This definitely falls into the nice-to-have category, something that one would only see if a certain flag is passed from the command line (like `--verbose`). We're curious what the thoughts are on your side.

ps. Thanks again for speaking at PyData Amsterdam.
