Link doesn't hide after some time capybara - ruby-on-rails

Question

I use capybara to test this code which located in my Comment model (5 minutes are conventional):
def editable?
self.created_at < (Time.now - 5.minute)
end
The view of link:
- unless comment.editable?
= link_to 'Edit', edit_category_theme_comment_path(#category, #theme, comment)
So after 5 minutes link to edit must hide from the page (but we need to refresh the page). Here is my code in RSpec for creating comments and testing the link-hide functionality:
def create_comment(options={})
options[:content] ||= 'I am a comment'
visit category_theme_path(category, theme)
within '.comment-form' do
fill_in 'Content', with: options[:content]
click_button 'Submit'
end
end
context 'Comment has content' do
before(:each) { create_comment }
it 'hides the edit symbol due 5 minutes after comment was created' do
using_wait_time 400 do
visit category_theme_path(category, theme)
save_and_open_page
expect(page).to have_no_css('.comment-edit')
end
end
end
But I got: Failure/Error: expect(page).to have_no_css('.comment-edit')expected #has_no_css?(".comment-edit") to return true, got false
I also try to use page.reload!, expect(page).to have_no_css('.comment-edit', wait: 400) and other related staff, but capybara don't want to wait. Maybe I use using_wait_time for a wrong place, if that - how I can test this?

Answer 1

There are a number of things wrong with your approach to testing this. The reason your attempt is failing is because using_wait_time just sets the amount of time Capybaras matchers will wait for their expectations to become true, it doesn't actually make the program wait. Therefore expect(page).to have_no_css('.comment-edit') will wait up to the time your using_wait_time specifies, rechecking the page every 50 milliseconds or so for the content, but it never reloads the page and doesn't wait before the loading the page. For your approach to work you would need to sleep before visiting the page
it 'hides the edit symbol due 5 minutes after comment was created' do
sleep 5.minutes
visit category_theme_path(category, theme)
save_and_open_page
expect(page).to have_no_css('.comment-edit')
end
however this is a terrible idea since your tests will become ridiculously slow.
Rather than that approach you could be generating your test comment already "old" (as pascal betz suggests), using something like FactoryGirl and specifying a created_at that is more than 5 minutes ago.
FactoryGirl.create(:comment, created_at: 5.minutes.ago)
or if you want to continue creating your comment through the interface then include something like the Timecop gem and you can do
Timecop.travel(5.minutes.from_now) do
visit category_theme_path(category, theme)
save_and_open_page
expect(page).to have_no_css('.comment-edit')
end
which will move the clock 5 minutes forward before visiting the page, and then reset it back to normal once the block if finished.
Additionally, your editable? method is comparing in the wrong direction and should be
def editable?
self.created_at > (Time.now - 5.minute)
end
Then the view should be
- if comment.editable?
= link_to 'Edit', edit_category_theme_comment_path(#category, #theme, comment)

Answer 2

Work with seed data that is 5 minutes old and visit that page. Like this you do not need to wait five minutes.
Also your code
- unless comment.editable?
= link_to 'Edit', edit_category_theme_comment_path(#category, #theme, comment)
should probably read
- if comment.editable?
= link_to 'Edit', edit_category_theme_comment_path(#category, #theme, comment)
