Test Erlang Code

Problem

You want to test your Erlang code using Cucumber-like syntax.

Ingredients

• cucumberl,^[266] a pure Erlang implementation of basic Cucumber syntax

• rebar^[267] for building cucumberl

Then, we’ll write a simple feature and see how to connect it to step definitions written in Erlang. Finally, we’ll see how Erlang’s pattern matching makes it easy to write multiple step definitions.
