Ruby on Rails: Cucumber: how to check the style tag of a particular element

Question

I have this

Then /^the "([^\"]*)" tag with the id "([^\"]*)" should have the style "([^\"]*)"$/ do |tag,id,style|
  if page.respond_to? :should
      page.should have_selector(tag, :id => id, :style => style)
    else
      assert page.has_selector?(tag, :id => id, :style => style)
    end
end

And This is my cuke step

    And the "div" tag with the id "preview" should have the style "display: block;"

And this is the error I get:

undefined method `has_selector?' for #<Capybara::Session:0x1065b5fc0> (NoMethodError)

Any ideas?

Answer 1

Try to use something similar to page.should have_xpath("//tag[@class='class', @id='id']")

Then /^I should see trivial div$/ do 
  page.has_xpath?("//div[@style='display:none' and @id='my_form']") 
end 

this one definitely works
