Debug output from webrat

Are there any ways to see debug output from webrat on failed steps?

For example I get the following error:

The 'Test User' option was not found in the "user_id" select box (Webrat::NotFoundError)

I want to see HT开发者_如何学编程ML output that webrat is seeing, to figure out, where is the problem.

Ok, i figured it out myself. Webrat has save_and_open_page method, it saves HTML page to tmp/ dir and opens it in browser.
