The step definitions

Given /^I have opened " ([^"]*) "$/ do | url |

visit url

end

When /^I search for " ([^"]*) "$/ do | query |

fill_in 'q' , :with => query

click_button 'Google Search'

end

Then /^I should see a link to " ([^"]*) " with text " ([^"]*) "$/ do | url , text |

response_body.should have_selector( "a[href='#{ url }']" ) do |element|

element .should contain( text )

end

end

Given definition

Given /^I have opened " ([^"]*) "$/ do | url |

visit url

end

When /^I search for "([^"]*)"$/ do |query|

fill_in 'q', :with => query

end

Then /^I should see a link to "([^"]*)" with text "([^"]*)"$/ do |url, text|

response_body.should have_selector("a[href='#{ url }']") do |element|

element.should contain(text)

end

end

When definition

Given /^I have opened "([^"]*)"$/ do |url|

visit url

end

When /^I search for " ([^"]*) "$/ do | query |

end

end

end

Then definition

visit url

end

end

Then /^I should see a link to " ([^"]*) " with text " ([^"]*) "$/ do | url , text |

response_body.should have_selector( "a[href='#{ url }']" ) do |element|

element. should contain( text )

end

end

Cucumber

Given /^I have opened "([^"]*)"$/ do | url |

visit url

end

When /^I search for "([^"]*)"$/ do | query |

end

Then /^I should see a link to "([^"]*)" with text "([^"]*)"$/ do | url , text |

end

end

webrat

visit url

end

end

response_body.should have_selector ("a[href='#{ url }']") do |element|

element.should contain (text)

end

end

RSpec

visit url

end

end

element. should contain(text)

end

end

Controller test

describe LoveController do

it { should route( :get , 'search' ).to( :action => :find ) }

describe 'lookin for love' do

before { get :find , :q => 'someone to hold me - ever so gently' }

it { should respond_with 404 }

it { should respond_with_content_type 'text/html' }

end

end

it { should route(:get, 'search').to(:action => :find) }

before { get :find, :q => 'someone to hold me - ever so gently' }

end

end

Shoulda

it { should route (:get, 'search'). to (:action => :find) }

before { get :find, :q => 'someone to hold me - ever so gently' }

end

end
