A modern programming language that makes developers happier.

Hi, I'm working through the _testing-hyperpyramid_ code and I wonder if the `e2e` module / `CustomerBuysItemScenario` was the starting point when developing outside-in?
I never did TDD, but I would like to try and I don't know where to start and if one could start with a module like `images`?

We tend to build up the scenarios incrementally.. so the very first slice would be a test which just did the action `listItens()` , or some other tiny vertical slice which threads through the entire system.

This process is defined pretty well in the GooS book (which is Java, but very worth reading if only for it's approach to software development): <http://www.growing-object-oriented-software.com/>

Obviously our process deviates somewhat (we don't recommend mocks for instance), but the grains of the approach are there
