You know why

HitchStory is a python 3 testing and living documentation framework for building easily maintained example driven executable specifications (sometimes dubbed acceptance tests).

It was designed initially to make realistic testing of code less of a goddamn chore so the tests would actually get written and run.

The executable specifications can be written to specify and test applications at any level and have been used successfully to replace traditional [low level unit tests](), [integration tests]() and [end to end tests]() with easier to maintain tests.

The specifications are written using StrictYAML and the code to execute them is written by you, in python.

Installation and set up

You can install hitchstory through pypi in any python 3 virtualenv:

$ pip install hitchstory

However, it’s recommended to install and set up hitchstory with hitchkey, which will take care of automatically setting up a up the recommended hitchstory environment.

Either install hitchkey with pipsi:

pipsi install hitchkey

Or, if you’d prefer, you can safely install with “sudo pip”:

sudo pip install hitchkey

Once hitchkey is installed:

Example demo of hitchstory basics:

cd temp
hk --demo hitchstory ; hk bdd email

Example python API test demo (uses game of life):

cd temp
hk --demo pythonapi ; cd pythonapi ; hk bdd
