Why does hitchstory mandate the use of given but not when and then?
Why is inheritance a feature of hitchstory stories?
Why does hitchstory not have an opinion on what counts as interesting to "the business"?
What does the license mean for me?
Why does hitchstory not have a command line interface?
Principles
Why does HitchStory have no CLI runner - only a pure python API?
Why Rewritable Test Driven Development (RTDD)?
Why does HitchStory use StrictYAML?
