Calling `rewire` in `setup` block fails about rewire

[stephanos]

You mean like this?

defmodule MyTest do
  use ExUnit.Case, async: true
  import Rewire                               
  
  setup do
    rewire MyModule, ...
  end

  test "start/0" do
    # MyModule is still the same, not the mocked one
  end
end

If that's the case, that would be expected behaviour. The rewire essentially becomes an alias here and will only be active inside the setup block's scope, not outside of it. Is there a reason you don't want to/can't put it outside of the setup block like in the README example?

Ah, I see now. Sorry, I just intuitively put it in the setup block and it seemed odd that it didn't work there. Putting it at the module level works for me 👍

Awesome! It's a good reminder for me to highlight this more in the README. I can totally see how you'd expect this.
