Subscribing to updates
You implement the on and off functionality simultaneously by writing a new feature
in a new file at features/watching_tickets.feature. Let’s start with the code from the
following listing.
Listing 12.6 features/watching_tickets.feature
Feature: Watching tickets
In order to keep up to date with tickets
As a user
I want to choose to subscribe to their updates
Background:
Given there are the following users:
| email | password |
| user@ticketee.com | password |
Given there is a project called "TextMate 2"
And "user@ticketee.com" can view the "TextMate 2" project
And "user@ticketee.com" has created a ticket for this project:
| title | description |
| Release date | TBA very shortly. |
Given I am signed in as "user@ticketee.com"
Given I am on the homepage
In this example, you create a single user, a project, and a ticket. Because this user created
the ticket, they’re automatically subscribed to watching this ticket and therefore
they should see the Stop Watching This Ticket button on the ticket page. You test this
by writing the scenario from the following listing underneath your Background.
Listing 12.7 features/watching_tickets.feature
Scenario: Ticket watch toggling
When I follow "TextMate 2"
And I follow "Release date"
Then I should see "user@ticketee.com" within "#watchers"
And I press "Stop watching this ticket"
Then I should see "You are no longer watching this ticket"
And I should not see "user@ticketee.com" within "#watchers"
To begin to watch a ticket again, all the user has to do is click the Watch This Ticket
button, which you can also test by adding the following code to this scenario:
When I press "Watch this ticket"
Then I should see "You are now watching this ticket"
And I should see "user@ticketee.com" within "#watchers"
See? That’s how you test the watching/not watching
function simultaneously! You don’t need to post a comment
and test that a user is truly watching this ticket; you
can instead check to see if a user’s name appears in a list
of all the watchers on the right side of the ticket page,
which will look like figure 12.8.
