README

A spike looking at adding basic given-when-then steps to ExUnit tests.

Features

• define tests as sequences of calls to given_, when_ and then_ (unfortunately when is a reserved word)
• match steps by calling defwhen etc with a string matching the one used in the step
• interpolate values into step descriptions using {braces}
• placeholder variable names are available as methods on the magic args variable
