Hello,
I have the following piece of code in tests:
defmodule DefTest do
use ExUnit.Case
defimpl Enumerable, for: __MODULE__ do
def reduce(map, acc, fun) do
1
end
def member?(_map, _other) do
{:ok, false}
end
def count(map) do
1
end
end
test "greets the world" do
assert Def.hello() == :world
end
end
and mix test
emits warning:
warning: the Enumerable protocol has already been consolidated, an implementation for DefTest has no effect
test/def_test.exs:4
What can I do ? The possible solution will be to put the test-class with protocol implementatition into lib
folder. That works, but I hope there can be better solution.
Thanks!
