rspec rails have_link, have_css

Found this extremely useful. If you want to test helpers or css code use this:

CREDITS TO

#Model 

 

@user.should have(1).error_on(:username) # Checks whether there is an error in username 

@user.errors[:username].should include("can't be blank")  # check for the error message 

 

#Rendering

response.should render_template(:index)

 

#Redirecting 

response.should redirect_to(movies_path)

 

#Capybara Matchers

 

response.body.should have_content("Hello world")

response.body.should have_no_content("Hello world")

 

response.body.should have_css("input#movie_title")

response.body.should have_css("input#movie_title", :value => "Twelve Angry Men")

response.body.should have_css("input", :count => 3) #True if there are 3 input tags in response

response.body.should have_css("input", :maximum => 3) # True if there or fewer or equal to 3 input tags 

response.body.should have_css("input", :minimum => 3) # True if there are minimum of 3 input tags 

response.body.should have_css("input", :between => 1..3) # True if there 1 to 3 input tags 

response.body.should have_css("p a", :text => "hello") # True if there is a anchor tag with text hello

response.body.should have_css("p a", :text => /[hH]ello(.+)/i) 

                                                   # True if there is a anchor tag with text matching regex

 

response.body.should have_xpath("//a")

response.body.should have_xpath("//a",:href => "google.com")

response.body.should have_xpath("//a[@href => 'google.com']")

response.body.should have_xpath("//a[contains(.,'some string')]")

response.body.should have_xpath("//p//a", :text => /re[dab]i/i, :count => 1)

 

 

# can take both xpath and css as input and can take arguments similar to both have_css and have_xpath

response.body.should have_selector(:xpath, "//p/h1")

response.body.should have_selector(:css, "p a#movie_edit_path")

 

# For making capybara to take css as default selector

Capybara.default_selector = :css

response.body.should have_selector("input")   #checks for the presence of the input tag

response.body.should have_selector("input", :value =>"Twelve Angry Men") # checks for input tag with value

response.body.should have_no_selector("input") 

 

# For making capybara to take css as default selector

Capybara.default_selector = :xpath

response.body.should have_selector("//input")   #checks for the presence of the input tag

response.body.should have_selector("//input", :value =>"Twelve Angry Men") # checks for input tag with value

 

 

# To access elements inside form 

response.body.should have_field("FirstName")  # checks for presence of a input field named FirstName in a form

response.body.should have_field("FirstName", :value => "Rambo")

response.body.should have_field("FirstName", :with => "Rambo")

 

response.body.should have_link("Foo")

response.body.should have_link("Foo", :href=>"googl.com")

response.body.should have_no_link("Foo", :href=>"google.com")
