Capybara aims to simplify the process of integration testing Rack applications,
|

such as Rails, Sinatra or Merb. It is inspired by and aims to replace Webrat

as a DSL for interacting with a webapplication. It is agnostic about the driver

running your tests and currently comes bundled with rack-test, Culerity and

Selenium support built in.

## Using Capybara with Cucumber
|
||||
|

Capybara is built to work nicely with Cucumber. The API is very similar to

Webrat, so if you know Webrat you should feel right at home. Remove any
|
||||
references to Webrat from your +env.rb+, if you're using Rails, make sure to set

* Unchecking checkboxes and filling in password fields is currently broken under Culerity.

You should use `page.should have_css('#header p')`,

`page.should have_xpath('//ul/li')` and `page.should have_content('Monkey')`

instead.
