Kale

Basic given-when-then steps for ExUnit tests. This is currently little more than a spike: it's probably not ready to use, and the API is certainly not stable.

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

• pass data between steps by calling save and get with a key

  • data is stored in a per-test Agent, allowing tests to run in parallel

TODO

• Remove the magic args, and save & get

  • Pass args and context via arguments to defwhen etc
  • Allow pattern matching
  • Return values to be saved from the function

Usage

See the tests for examples.

Why Kale?

As a nod to Spinach.
