Pagination
the tickets page with more than 50 tickets in the system, you will see a pagination link
somewhere on that page. You should be able to click Next and then see the next 50
tickets.
16.1.2 Paginating an interface
You’re going to now implement paging for your tickets listing, showing 50 tickets at a
time. Users will be able to navigate between pages by clicking the Next and Prev links.
These two links will be provided by a helper from the kaminari gem.
TESTING PAGINATION
To test this, you’ll write a new scenario at features/paginating_tickets.feature, shown in
the following listing. If you create 100 tickets in this feature, you’ll see the pagination
links and can then make sure they’re working.
Listing 16.1 features/paginating_tickets.feature
Feature: Paginating tickets
In order to ease the load on the server
As the system
I want paginate ticket results
Background:
Given there is a project called "Internet Explorer"
Given there are the following users:
| email | password |
| user@ticketee.com | password |
And "user@ticketee.com" can view the "Internet Explorer" project
And I am signed in as them
And there are 100 tickets for this project B Create tickets
When I am on the homepage
And I follow "Internet Explorer"
Scenario: Viewing the second page
Then I should see 2 pages of pagination
When I follow "Next" within ".pagination .next"
Then I see page 2 of tickets for this project
In this feature you use the “Given there is a project” step you’ve used many times
before to create a project, and then a new step B, which will create a given number of
tickets for the project. This is required so that the pagination links will appear on your
tickets. If you didn’t have enough tickets in your project to warrant pagination, then
the links would not appear at all.
You then go through the motions of creating a user, giving them access to that
project so that they can see into it, signing in as them, and then navigating to that
project. On that project’s page you should see the pagination links displaying two
pages’ worth of pagination. When you click the Next link within the pagination element,
you should be on the second page.
You’ve got three undefined steps within this feature, and you can get the step definitions
for these steps by running this feature using the bin/cucumber features/
