Behaviour for Ersatz startup configuration

This module should be configured in Mix.Config and available at config :ersatz, config: Mock.Config

Using the mechanism will set Ersatz in global mode for your mocks to be available in your Application thread.

As well as the mock.ex, mock_config.ex should be compiled with the rest of the project. Edit your mix.exs file to add the test/support directory to compilation paths:

def project do
  [
    ...
    elixirc_paths: elixirc_paths(Mix.env),
    ...
  ]
end

defp elixirc_paths(:test), do: ["test/support", "lib"]
defp elixirc_paths(_),     do: ["lib"]
