A library for property based testing
Project description
Hypothesis is a library for testing your Python code against a much larger range of examples than you would ever want to write by hand. It’s based on the Haskell library, Quickcheck, and is designed to integrate seamlessly into your existing Python unit testing work flow.
Hypothesis is both extremely practical and also advances the state of the art of unit testing by some way. It’s easy to use, stable, and extremely powerful. If you’re not using Hypothesis to test your project then you’re missing out.
Hypothesis works with most widely used versions of Python. It officially supports CPython 2.7, 3.4 and 3.5, as well as PyPy. Most other versions of Python are known not to work.
