Answer 1

I found that those docs were missing a few details and moving from 2.1 => 2.2 took quite some time. Here are my notes:

Biggest time sink: assert_redirected_to has changed significantly, no longer supporting hashes (at all?)

• Lighthouse entry
• More on problems with assert_redirected_to under Rails 2.2.2

Also, need to set environment/test.rb to disable forgery protection

If anyone's got news on these points for 2.3 that'd be super awesome.
