Capybara and remote links - ruby-on-rails

I have this link in records_path page:
link_to "CLICK HERE", edit_record_path(record), remote: true
The controller:
def edit
puts request.format # Just to show you part of the issue
end
And when clicked, it executes the edit.js.coffee and renders a modal for editing the record.
It works great. The problem I have is with Capybara.
context 'when on records list page' do
before { visit records_path }
context 'when clicking on "CLICK HERE"', js: true do
before { click_link('CLICK HERE') }
it 'shows the record name' do
expect(page).to have_content record.name
end
end
end
When I run the test, it raise an error:
Capybara::ElementNotFound: Unable to find link "CLICK HERE"
But if I remove the js: true from the context, it works (It executes the edit method on the RecordsController) but the printed format is html instead of js. I don't even have an edit.html, I just have the edit.js.coffee and that is the one that should be rendered in the test.
What am I doing wrong? If the link has the remote: true prop, and the test has the js: true shouldn't be enough for make it work?

In your setup you don't actually create a record. I am assuming this is the cause of your problem. The edit_record link will not show up if you do not have records to edit. I could be wrong but from what you pasted I think this could be the cause.

How do I confirm a css element attribute with Capybara?

This may seem unusually basic but how do I confirm the presence of a pop up confirmation?
<a data-confirm="delete this video?" rel="nofollow" data-method="delete" href="/videos/21">Delete</a>
<a is the "tag"/"element" and data-confirm is an attribute. I want to test for the existence of the "data-confirm" attribute within the <a> element/tag
I have tried
expect(page).to have_css("a.data-confirm.delete this video?")
from
capybara assert attributes of an element
but no joy.
Edit:
I've tried the expectation from Arup's comment below
expect(page).to have_content "Content"
click_link "Delete"
expect(page).to have_css('a[data-confirm="delete this video?"]')
But it raises the following (same) error
Failures:
1) Visiting the video index page should search and save movies
Failure/Error: expect(page).to have_css('a[data-confirm="delete this video?"]')
expected #has_css?("a[data-confirm=\"delete this video?\"]") to return true, got false
but the page source shows it there and it is clearly working for the user
Any assistance would be very appreciated
You can write this expectation as:
expect(page).to have_css('a[data-confirm="delete this video?"]')
The answer by Arup is correct for the title of the question (and as he stated in the comments it's just valid CSS - https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors), however it's not actually testing the more detailed part of the question "how do I confirm the presence of a pop up confirmation". All it is doing is confirming the correct data attribute is on the link element to trigger the rails provided JS that should show a confirm.
If you wanted to actually test the confirm box is shown you would need to swap to using a JS capable driver - https://github.com/teamcapybara/capybara/tree/2.17_stable#drivers - and then use something like the following in your test
expect(page).to have_content "Content"
accept_confirm "delete this video?" do
click_link "Delete" # The action that will make the system modal confirm box appear
end
See - http://www.rubydoc.info/gems/capybara/Capybara/Session#accept_confirm-instance_method

Tests UJS Rails with Capybara, Selenium and Rspec

On my page I have :
-->a form that scrapes the content of another website with a Ajax request made with ujs (remote: true):
<%= simple_form_for #listing, :url => listings_fetch_url, remote: true do |f| %>
<%= f.input :url %>
<%= f.button :submit, id: 'import_button' %>
<% end %>
-->another form that is populated by the scraping results from the form above
Manually it works...
However when I'm trying to automatically test it, it doesn't.
Capybara finds the submit button, clicks on it but then it leaves me on a blank page.
Here is the code for the test:
feature "Listing import" do
scenario "fills in the form fields", js: true do
visit new_search_path
fill_in 'Url', :with => 'www.google.fr'
find('input#import_button').click
expect(page.body).to have_content 'query was'
end
end
The controller actions are the following:
def fetch
url = listing_params[:url]
#query = Query.new(ScraperService.new({url: url}).perform)
render :fill
end
# Renders an js.erb file
def fill
end
It seems like rspec with selenium can't render js.erb files?
Any help is appreciated!
EDIT
Thanks to #ThomasWalpole, I fixed an error 500 which was preventing Mechanize to scrape the web. The content is now scraped correctly but the problem remains: the page after clicking on the submit button becomes blank and the tests ends right afer.
In the logs I have a lengthy message :
Could not log "render_template.action_view" event. NoMethodError:
undefined method example_group' for nil:NilClass
["/Users/Greg/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/rspec-rails-3.6.0/lib/rspec/rails/view_rendering.rb:67:in
current_example_group'"
Which seems to be the same problem as : 1 & 2
Solved it!
The problem came from the fact that my js.erb wasn't adding a new element on the current page (i.e.: a new class, a new id, a new DOM element...).
Capybara never waited for the Ajax request to complete!
I appended a new line to my js.erb:
$("#import_button").addClass("imported");
This way I know that when the class imported is present on the current page it means the Ajax request is over.
Then in my test I added the following line:
expect(page).to have_selector :css, '#import_button.imported', wait: 10
Everything works fine now 🤘
P.S.: this website helped me understand the problem as well

Testing ruby with rails, Element not found

I get the error:
Capybara::ElementNotFound:
Unable to find field "user_email"
And this is the test code:
feature 'User' do
given!(:user) { User.new(email: 'testuserid#example.com', encrypted_password: 'test') }
scenario 'opens sign_up page' do
visit new_user_session_path
expect(page).to have_content 'unique text on the page'
end
scenario 'signs in with invalid email' do
visit new_user_session_path
fill_in('user_email',with: 'ssd')
expect(page).to have_content 'unique text on the page'
end
end
My HTML file consists of this code literally:
unique text on the page
<br>
<input type="text" id="user_email">
So this proves that the path is correct because my first scenario runs correctly. It is visiting the right page. But still I get this error for second scenario in fill_in.
I have also tried element = page.find("user_email"), it gives same error.
What am I possibly doing wrong?
I have been scratching my head like hell.
Usually the reason for this is that the input isn't actually visible on the page. You can verify this by doing
fill_in('user_email', with: 'ssd', visible: false)
If that succeeds in finding the element, then you need to change your test to first perform whatever actions make the field visible before attempting to fill it in.
Your code seems right. Maybe you are visiting wrong url or you have used user_email id once more. But you can give a try with alternative syntax like following :
find("input[id$='user_email']").set "ssd"

Capybara matcher for presence of button or link

Users on web page don't distinguish between "button" and "link styled as button".
Is there a way to add check whether a "button or link" is present on page?
For example Capybara has step:
page.should have_button('Click me')
which does not find links styled as buttons.
Updated answer (should matcher is deprecated in RSpec 3.0+):
expect(page).to have_selector(:link_or_button, 'Click me')
Before:
page.should have_selector(:link_or_button, 'Click me')
Followed from click_link_or_button which is defined here: https://github.com/jnicklas/capybara/blob/master/lib/capybara/node/actions.rb#L12
def click_link_or_button(locator)
find(:link_or_button, locator).click
end
alias_method :click_on, :click_link_or_button
It calls a selector :link_or_button. This selector is defined here: https://github.com/jnicklas/capybara/blob/master/lib/capybara/selector.rb#L143
Capybara.add_selector(:link_or_button) do
label "link or button"
xpath { |locator| XPath::HTML.link_or_button(locator) }
end
It calls this method: http://rdoc.info/github/jnicklas/xpath/XPath/HTML#link_or_button-instance_method
# File 'lib/xpath/html.rb', line 33
def link_or_button(locator)
link(locator) + button(locator)
end
So i tried to check the presence of the selector and it worked:
page.should have_selector(:link_or_button, 'Click me')
Using the expect syntax
expect(page).to have_selector(:link_or_button, 'Click me')
This works without needing to define a custom matcher.
You can also use a custom matcher
RSpec::Matchers::define :have_link_or_button do |text|
match do |page|
Capybara.string(page.body).has_selector?(:link_or_button, text: text)
end
end
Then do
expect(page).to have_link_or_button('Login')
Personally I would give your button or link an id and look for that using
page.should have_css('#foo')
This way you can refer to the link or button without worrying about its implementation.
I always find this useful: https://gist.github.com/428105
I think you can use the find button instance method:
(Capybara::Element) find_button(locator)
Using id, name, value.
Or if you want a link
(Capybara::Element) find_link(locator)
From: http://rubydoc.info/github/jnicklas/capybara/master/Capybara/Node/Finders#find_button-instance_method
I had an odd case where some smoke tests marched across various customer-centric login pages that had slight variations on doing the login submit button... Driven by a Cucumber table of user, org, etc.
# A bit of a hack, org_name is normally a subdomain, but sometimes it is the complete domain
def login(user, org_name)
# Use the below to automatically hit each user's org's server
if org_name.include? '.com'
Capybara.app_host = "http://#{org_name}"
else
Capybara.app_host = "http://#{org_name}.mydomain.com"
end
visit '/'
fill_in 'username', :with => user
fill_in 'userpwd', :with => '***'
begin
page.find(:link_or_button, 'submit')
click_on 'submit'
rescue Capybara::ElementNotFound
page.find(:link_or_button, 'Log In')
click_on 'Log In'
rescue Capybara::ElementNotFound
pending "Need to determine how to invoke the Login button for #{org_name} near Line ##{__LINE__} of #{__method__} in #{__FILE__} "
end
# -----------------------
# Work-around for modal popup saying SSL is mismatched if you are using actual production URLs
# The rescue is for cases that do not exhibit the modal pop-up
page.driver.browser.switch_to.alert.accept rescue Selenium::WebDriver::Error::NoAlertPresentError
# Ensure that login was successful
page.should_not have_content 'Login failed'
end
if html:
<a class="top-menu__item">text123
<span class="label">
<span class="label">86</span>
</span>
</a>
not work:
assert page.has_selector?(:link_or_button, text: 'text123')
assert page.should have_selector(:link_or_button, text: 'text123')

How do I simulate an "Edit" or "Destroy" button click in Rails 3.2 w/ MiniTest?

How can I write an integration test for editing an item? My "create" test looks like this:
it "lets a user create a product" do
login_user
click_link("Products")
click_link("New")
fill_in "Identifier", :with => "MyString"
click_button "Create"
assert page.has_content?("Product was successfully created")
end
And that works great. What I am confused about is how to do the Edit and Destroy tests. My index page provides a list of all products. So first I use a factory to create a couple of products. Now I am in the situation where there are multiple "Edit" and "Destroy" buttons. I can't just say:
click_button "Destroy"
because there are two of them. How do I tell it which one to click?
And if I do get the correct "Destroy" button clicked, how do I hit the "OK" button in the Javascript window that pops up?
Assuming that you're using Webrat, you can use the "within" selector.
The Webrat "within" method takes a CSS selector as an argument. Supposing your "Destroy" button is in a div with an id like "#product-2", you can isolate that button with:
within "#product-2" do |scope|
scope.click_button "Destroy"
end
If you need to / would rather use XPath, you can do something like:
response.should have_xpath(xpath) do |button|
click_button(button)
end
Alternatively, if you are using Capybara, then you can use the "find" method:
find("#product-2").find("button").click
find(:xpath, "//div/div/button").click
