Junk

Junk is a module for generating Junk data in your tests. For when you don't care about the content, just that it has the right 'shape'. It is inspired by Dave Brady's rspec-junklet

Example

defmodule ExampleTest do
  import Junk 

  test "example test" do
    thing = %{
      name:    junk, # defaults to junk(String)
      some_id: junk(Integer, size: 9)
    }
    struct(SomeThing, thing)
    |> SomeThing.push

    assert SomeThing.pop == thing
  end
end

Usage
