Numpy Beginner's Guide (Update)

Nose test decorators

A nose is an organ above the mouth that is used by humans and animals to breathe and smell. It is also a Python framework that makes (unit) testing easier. Nose helps you organize tests. According to the nose documentation:

"Any python source file, directory or package that matches the testMatch regular expression (by default: (?:^|[b_.-])[Tt]est) will be collected as a test."

Nose makes extensive use of decorators. Python decorators are annotations that indicate something about a method or a function (see http://thecodeship.com/patterns/guide-to-python-function-decorators/). The numpy.testing module has a number of decorators. The following table shows the different decorators in the numpy.testing module:
