use ExUnit.Case
use SetupTag
def one(ctx), do: {:ok, Map.put(ctx, :one, 1)}
def dup_one(ctx = %{one: x}), do: {:ok, %{ctx | one: x + x }}
def mul_one(ctx = %{one: x}, y), do: {:ok, %{ctx | one: x * y }}
@tag setup: [:one, :dup_one, mul_one: 3]
test "combining with a function with arguments", %{one: x} do
assert x == 6
