[Neuroimaging] advice on choosing a testing library

[Jasper van den Bosch]

I have never felt like I missed out when using unittest. The reason I've
known people to choose nose or py.test is that you need less boilerplate
code.

But when you need to test hierarchies of classes, being used to the
object-oriented style of unittest pays off.
