I am using Cucumber / Capybara with Rails 3 and am trying to validate the existence of an image after upload. I'm not sure how to check the url of the image to validate it.
I have the following scenario:
Scenario: Create new listing
Given I am on the new listing page
When I fill in "listing_name" with "Amy Johnson Photography"
And I attach the file "features/support/test_image.jpg" to "listing_images_attributes_0_photo"
And I press "Create"
Then I should see "Amy Johnson Photography"
And I should see the image "test_image.jpg"
Everything passes except the last step.
I've tried this for my step definition, which works great if it's text on the page, but doesn't for an image url:
Then /^I should see the image "(.+)"$/ do |image|
if page.respond_to? :should
page.should have_content(image)
else
assert page.has_content?(image)
end
end
Then I've also tried something like this step definition instead:
Then /^I should see the image "(.+)"$/ do |image|
html = Nokogiri::HTML(response.body)
tags = html.xpath('//img[@src="/public/images/foo.png"]')
# tags.length.should eql(num_of_images)
end
which causes the following error:
And I should see the image "test_image.jpg" # features/step_definitions/listing_steps.rb:41
undefined method `body' for nil:NilClass (NoMethodError)
./features/step_definitions/listing_steps.rb:42:in `/^I should see the image "(.+)"$/'
features/manage_listings.feature:24:in `And I should see the image "test_image.jpg"'
I'm assuming you need a nokogiri step to find this properly. Or if there's a better way, I'm open to suggestions. How can I validate that the image I just uploaded is on the page? Thanks.
The solution with Nokogiri should work fine. The only problem is that the Cabybara API is different to Webrat, so instead of response.body
, you must use page.body
.
But theres an even better way to test for the image with Cabybara :
Then /^I should see the image "(.+)"$/ do |image|
page.should have_xpath("//img[@src=\"/public/images/#{image}\"]")
end
Hi I'm not good with XPATH but with CSS you can try :
if page.respond_to? :should page.should have_selector("img[src$='#{imagename}']") else assert page.has_selector?("img[src$='#{imagename}']") end
wish helps ! jramby
You can test it in this way, and also not depending on the path:
Then /^I should see the image "(.+)"$/ do |image|
page.should have_xpath("//img[contains(@src, \"#{image}\")]")
end
page.should
is now deprecated. Use instead
expect(page).to
Full example :
Then /^I should see the image "(.+)"$/ do |image|
expect(page).to have_xpath("//img[contains(@src, \"#{image}\")]")
end
这有用吗?
page.should have_xpath('//img[@src="/public/images/foo.png"]')
If you have a lot of images that you would like to test you could create a has_image? matcher for Capybara.
It is easy and this post explains it step-by-step: Adding a has_image? Matcher to Capybara
Yes, but these xpath tests won't deal with the fact that...
/public/images/foo.jpg
public/images/foo.jpg
http://mydomain.com/public/images/foo.jpg
...are all the same valid link to the image.
this syntax worked for me and is more readable.
page.should have_css("img", :src => "/public/images/foo.png")
