I'm always very careful when placing code supporting the test outside of the test itself. Setup and teardown functions are fine, but I prefer to be safe because, well, you can't test the test.

-- I'm not saying this is the case in the blog post. Just some thoughts.

If a macro used for a test suite is substantial enough and used often I'd say it's worth testing

True. It's an Elixir best practice to keep macro definitions short and basically make them invoke functions as match as possible.

No perfect answer I guess...
