Capybara
2 likes1,906 views
Capybara is a tool for integration testing Ruby web applications that allows automating browser interactions directly from tests. It is driver agnostic and supports RackTest, Selenium, Capybara-webkit, and other drivers, and provides a DSL for writing tests that simulate user interactions like clicks, fills, and matches against page content. Capybara tests can be written using Cucumber or RSpec and configured to run quickly using headless drivers or remotely on servers.
![google_steps.rb
When /^I search google for "([^"]*)"$/ do |search_string|
visit("http://google.com")
fill_in ('q', :with => search_string)
click_button ('Search')
end
Then /google should .+ "([^"]*)"/ do |expected_substring|
page.should have_content(expected_substring)

Capybara
- 1. Capybara
- 2. backend for Ruby DSL Cucumber Capybara driver agnostic RackTest - Selenium - default default browser javascript driver
- 3. set it up !! sudo gem install capybara rails app : rails generate cucumber:install -- capybara non rails app : require 'capybara/cucumber' Capybara.app = MyRackApp https://github.com/jnicklas/capybara
- 4. all about drivers Capybara.javascript_driver = :selenium Capybara.default_driver = :selenium register new driver Capybara.register_driver :celerity do |app| Capybara::Driver::Celerity.new(app,:browser => :chrome) end Currently supported drivers RackTest Selenium 2.0 - Webdriver HtmlUnit - Akephalos, Celerity, Culerity Capybara-webkit
- 5. capybara dsl navigation - visit clicks - click_link finders - find_field matchers - page.has_xpath? actions - fill_in scope - within scripting - page.execute_script() http://rubydoc.info/github/jnicklas/capybara/master
- 6. google_steps.rb When /^I search google for "([^"]*)"$/ do |search_string| visit("http://google.com") fill_in ('q', :with => search_string) click_button ('Search') end Then /google should .+ "([^"]*)"/ do |expected_substring| page.should have_content(expected_substring) end
- 7. reduce build time tagging use headless webdriver
- 8. what else? capybara-firebug use capybara with rspec run on remote server using Capybara.run_server = false supports both xpath and css http://google-opensource.blogspot.com/2009/05/introducing- webdriver.html
