API

Navigation visit "/hotels/new" visit hotels_path

Navigation click_link "Create a new hotel"

Navigation click_area 'Madrid'

Forms select "Canada", :from => "Country" select "Canada"

Forms

Forms select_date "April 26, 1982", :from => "Birthday" select_date Date.today select_datetime 2.days.ago select_datetime "April 26, 1982 7:00PM", :from => "Event" select_time "22:30" select_time "1:30AM", :from => "Arrival time"

Forms attach_file "Brochure", "/path/nh_cornella.pdf" attach_file "Photo", "/path/front.jpg", "image/jpg"

Forms check 'Remember me' uncheck 'You can send me spam'

Forms fill_in "Email", :with => "user@example.com" fill_in "user[email]", :with => "user@example.com"

Forms click_button "Login" click_button

And more... basic_auth "admin", "password" save_and_open_page

And more... within "#project_1" do click_link "Destroy" end

Matchers assert_contain "Hotel was successfully created" assert_not_contain(/You have booked for d+ nights/)

Matchers assert_have_selector "div#hotel_1", :content => "Sol Meliá Berlín" assert_have_selector ".bookings", :count => 5 assert_have_no_selector "a:enabled", :href => "http://google.com"

Matchers assert_have_xpath "//div[@id = 'hotel_1']", :content => "Sol Meliá Berlín" assert_have_xpath "//*[@class = 'bookings']", :count => 5 assert_have_no_xpath "//a[enabled(.)]", :href => "http://google.com"

Matchers response.should contain(/You have booked for d+ nights/) response.should_not have_selector(".bookings", :count => 5)

Matchers response.should have_selector(".hotels") do |hotels| hotels.should have_selector("h2", :content => "Hotels") hotels.should have_xpath("//div[@id = 'hotel_1']", :content => "Ritz") end

Configuration

Webrat.configure do |config| config.parse_with_nokogiri = true config.infinite_redirect_limit = 10 config.open_error_files = true end
