The code on page 16 of beta 6 uses `setup_all` but I believe this should be `setup`. The code in `response_parser_test.bak.exs` uses `setup` and the use of `setup_all` throws an error.

Yep, I’ve just found this too.

Unfortunately, the book has been finalized now, so I doubt they’ll fix it. Maybe they will publish fixed versions of the ebooks?

Interestingly, this error is not present in B4, but it is in the final Beta (B7).

I know they are demonstrating the use of `setup` here, but considering that the setup block is only used by the first test, it would be better to just do it as part of that test. As a compromise, a better fix might be to move the `setup_all` block outside of the `describe` block, so that it only runs once for all the tests.
