defmodule Couch.Test.Setup.Step do
@moduledoc """
A behaviour module for implementing custom setup steps for future reuse.
Every module implementing this behaviour must implement following three functions:
- new
- setup
- teardown
Here is an example of a custom step
```
defmodule Couch.Test.Setup.Step.Foo do
alias Couch.Test.Setup
defstruct [:foo_data, :foo_arg]
def new(setup, id, arg: arg) do
setup |> Setup.step(id, %__MODULE__{foo_arg: arg})
end
def setup(_setup, %__MODULE__{foo_arg: arg} = step) do
...
foo_data = ...
%{step | foo_data: foo_data}
end
def teardown(_setup, _step) do
end
def get_data(%__MODULE__{foo_data: data}) do
data
end
end
```
