314 CHAPTER 12 Sending email
To test all this, you’ll use the email_spec gem, which you first used back in
chapter 6. This gem provides very useful Cucumber steps (and RSpec helpers!) that
allow you to easily verify that an email was sent during a test, and you’ll be taking full
advantage of these steps in the feature that you’ll be writing right now.
12.1.1 Automatically watching a ticket
This feature will initially test that a user automatically watches a ticket when they create
it. Whenever someone else updates this ticket, the user who created it (and later,
anybody else watching the ticket) will receive an email notification. You put this new
feature in features/ticket_notifications.feature and fill it with the content from the following
listing.
Listing 12.1 features/ticket_notifications.feature
Feature: Ticket Notifications
Background:
Given there are the following users:
| email | password |
| alice@ticketee.com | password |
| bob@ticketee.com | password |
Given a clear email queue
Given there is a project called "TextMate 2"
And "alice@ticketee.com" can view the "TextMate 2" project
And "bob@ticketee.com" can view the "TextMate 2" project
And "alice@ticketee.com" has created a ticket for this project:
| title | description |
| Release date | TBA very shortly. |
Given I am signed in as "bob@ticketee.com"
Given I am on the homepage
Scenario: Ticket owner is automatically subscribed to a ticket
When I follow "TextMate 2"
And I follow "Release date"
And I fill in "Text" with "Is it out yet?"
And I press "Create Comment"
B Clear received emails
Then "alice@ticketee.com" should receive an email
When "alice@ticketee.com" opens the email
Then they should see "updated the Release date ticket" in the email body
And they should see "[ticketee] TextMate 2 -
Release date" in the email subject
Then they click the first link in the email
Then I should see "Release date" within "#ticket h2"
You use the “Given a clear email queue” step B near the top of your Background,
which will clear out any received emails from ActionMailer::Base.deliveries
where the test deliveries are stored. This is important because two confirmation emails
get sent out when you create the users, and you don’t want your “should receive an
email” step in the scenario to retrieve those instead.
