## Description:
2009-11-04 22:00:05 +00:00
2009-11-18 23:00:10 +00:00
Capybara aims to simplify the process of integration testing Rack applications,
2009-11-18 23:15:46 +00:00
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
2009-11-18 23:00:10 +00:00
running your tests and currently comes bundled with rack-test, Culerity and
Selenium support built in.

Capybara is alpha level software, don't use it unless you're prepared to get
your hands dirty.

## Using Capybara with Cucumber
2009-11-04 22:00:05 +00:00
2009-11-18 23:00:10 +00:00
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
2009-11-18 23:15:46 +00:00
references to Webrat from your `env.rb`, if you're using Rails, make sure to set
2009-11-04 22:00:05 +00:00
2009-11-18 23:00:10 +00:00
Cucumber::Rails::World.use_transactional_fixtures = false
2009-11-04 22:00:05 +00:00
2009-11-18 23:00:10 +00:00
Capybara uses DatabaseCleaner to truncate the database. Require Capybara in your
env.rb. For Rails do this:
require 'capybara/rails'
require 'capybara/cucumber'
For other frameworks, you'll need to set the Rack app manually:
require 'capybara/cucumber'
Capybara.app = MyRackApp
Now you can use it in your steps:
When /I sign in/ do
within("//form[@id='session']") do
fill_in 'Login', :with => 'user@example.com'
fill_in 'Password', :with => 'password'
end
click_link 'Sign in'
2009-11-15 01:13:07 +00:00
end
2009-11-04 22:00:05 +00:00
2009-11-18 23:15:46 +00:00
## Default and current driver
2009-11-18 23:00:10 +00:00
2009-11-18 23:15:46 +00:00
You can set up a default driver for your features. For example if you'd prefer
to run Selenium, you could do:
2009-11-18 23:00:10 +00:00
require 'capybara/rails'
require 'capybara/cucumber'
Capybara.default_driver = :selenium
You can change the driver temporarily:
Capybara.current_driver = :culerity
Capybara.use_default_driver
2009-11-18 23:15:46 +00:00
## Cucumber and Tags
2009-11-18 23:00:10 +00:00
2009-11-18 23:15:46 +00:00
Capybara sets up some [tags](http://wiki.github.com/aslakhellesoy/cucumber/tags)
for you to use in Cucumber. Often you'll want to use run only some scenarios
with a driver that supports JavaScript, Capybara makes this easy: simply tag the
scenario (or feature) with `@javascript`:
2009-11-18 23:00:10 +00:00
@javascript
Scenario: do something AJAXy
When I click the AJAX link
...
You can change which driver Capybara uses for JavaScript:
Capybara.javascript_driver = :culerity
2009-11-18 23:15:46 +00:00
There are also explicit `@selenium`, `@culerity` and `@rack_test` tags set up
for you.

## The API
2009-11-18 23:00:10 +00:00
Navigation:
visit The only way to get to anywhere.

2009-11-18 23:00:10 +00:00
find_field
find_link
find_button
field_labeled
Debugging:
save_and_open_page
2009-11-18 23:15:46 +00:00
## Using the DSL outside cucumber
2009-11-18 23:00:10 +00:00
You can mix the DSL into any context, for example you could use it in RSpec
examples. Just load the dsl and include it anywhere:
2009-11-04 22:00:05 +00:00
2009-11-16 21:02:16 +00:00
require 'capybara'
require 'capybara/dsl'
2009-11-18 23:00:10 +00:00
2009-11-16 21:02:16 +00:00
include Capybara
Capybara.default_driver = :culerity
2009-11-15 01:13:07 +00:00
within("//form[@id='session']") do
fill_in 'Login', :with => 'user@example.com'
fill_in 'Password', :with => 'password'
end
click_link 'Sign in'
2009-11-18 23:15:46 +00:00
## Using the sessions manually
2009-11-15 01:13:07 +00:00
2009-11-18 23:00:10 +00:00
For ultimate control, you can instantiate and use a session manually.
2009-11-15 01:13:07 +00:00
2009-11-18 23:00:10 +00:00
require 'capybara'
2009-11-15 01:13:07 +00:00
2009-11-18 23:00:10 +00:00
session = Capybara::Session.new(:culerity, my_rack_app)
session.within("//form[@id='session']") do
session.fill_in 'Login', :with => 'user@example.com'
session.fill_in 'Password', :with => 'password'
2009-11-15 01:13:07 +00:00
end
2009-11-18 23:00:10 +00:00
session.click_link 'Sign in'
2009-11-15 01:13:07 +00:00
2009-11-18 23:15:46 +00:00

2009-11-18 23:15:46 +00:00
## Gotchas:
2009-11-15 01:13:07 +00:00
2009-11-18 23:15:46 +00:00
* Everything is *case sensitive*. Capybara heavily relies on XPath, which
doesn't support case insensitive searches.
2009-11-18 23:00:10 +00:00
2009-11-18 23:15:46 +00:00
* The `have_tag` and `have_text` matchers in RSpec-Rails are not supported.
You should use `page.should have_css('#header p')`,
`page.should have_xpath('//ul/li')` and `page.should have_content('Monkey')`
instead.
2009-11-18 23:00:10 +00:00
2009-11-18 23:15:46 +00:00
* Unchecking checkboxes and filling in password fields is currently broken under
Culerity.
2009-11-18 23:00:10 +00:00
2009-11-18 23:15:46 +00:00
* Domain names (including subdomains) don't work under rack-test. Since it's a
pain to set up subdomains for the other drivers anyway, you should consider an
alternate solution. You might use
2009-11-18 23:17:20 +00:00
[default_url_options](https://gist.github.com/643a758320a2926bd2ed) in Rails
2009-11-18 23:15:46 +00:00
for example.
2009-11-18 23:00:10 +00:00
2009-11-18 23:15:46 +00:00
* The `set_hidden_field` method from Webrat is not implemented, since it doesn't
work in any of the browser based drivers (Culerity, Selenium)
2009-11-18 23:00:10 +00:00
2009-11-18 23:15:46 +00:00
* Access to session, request and response from the test is not possible. Maybe
we'll do response headers at some point in the future, but the others really
shouldn't be touched in an integration test anyway.
2009-11-04 22:00:05 +00:00
2009-11-18 23:15:46 +00:00
* Access to Rails specific stuff (such as `controller`) is unavailable, since
we're not using Rails' integration testing.
* `<a href="#">` Will cause problems under rack-test, please do
`<a href="/same/url#">` instead. You can achieve this in Rails with
`link_to('foo', :anchor => '')`
