Tracking down the root of an unmet expectation is even trickier when you can’t see what the expectation is being compared to… one great resource I’ve been using as-of-late is cucumber_rails_debug. Here’s the readme, in all of its complexity:

Usage:

Add:

require ‘ruby-debug’
require ‘cucumber_rails_debug/steps’

To features/support/env.rb

Then use:

Then debug # opens the debugger
or
Then what #prints out params, url and html

Simply being able get a hold of the resulting html by saying Then what has proven immensely helpful.
