Not sure if you are aware of this...for the first edition of your tutorial, webrat is required for many of the tests (I tested on ubuntu/windows), but inclusion of webrat will actually break some of the new tests (like those using have_selector) in the second edition. You might want to add a warning to those who have followed the first edition and are trying to incorporate the additions in the second edition.

The 2nd edition explicitly uses Capybara instead of Webrat. As long as people pay attention to their Gemfiles, they should be fine.

It would be nice if you can discuss the differences, like how Capybara is meant for integration tests, and replacement for have_template etc. At some sections the tests are still referred to controller tests (Listing 10.46) although it looks like you intend to convert them all to integration tests.

Also, 11.37 tests do not work with valid_sign_in (using session authentication), but works with the controller.sign_in method introduced in 1e.
