Rails%203%20In%20Action

Real-world email
In this step definition, you need to tell Action Mailer to use SMTP to deliver your
emails rather than capture them. You can define this new step definition in features/
step_definitions/app_email_steps.rb like this:
Given /^Action Mailer delivers via SMTP$/ do
ActionMailer::Base.delivery_method = :smtp
end
Great! Now Action Mailer will set the delivery_method to :smtp before every scenario
in this feature. The side effect of this setting is that it will be set for every scenario that
runs after it, not only scenarios in this feature. This is a problem because you don’t
want every scenario to send email in the real world, only the ones contained in this
feature. To make it revert this setting back to :test after every scenario, you can create
a new file at features/support/after_hook.rb and put this content inside it:
After do
ActionMailer::Base.delivery_method = :test
end
The After method here is provided by Cucumber, and its purpose is to execute any
given block after each scenario has finished running. With this code, the setting will
be reverted back to :test and you’ll only be sending real-world emails in this particular
scenario.
Let’s continue writing your new feature. You need to set up a project that both
alice@ticketee.com and you can see, and create a ticket on that project that is posted
by you. In a short while, you’ll get Alice to sign in and post a comment to this ticket,
which should make an email appear in your inbox. You’ll then check this email using
the mail gem. Set up the project and ticket with these steps:
Given there is a project called "TextMate 2"
And "alice@ticketee.com" can view the "TextMate 2" project
And "youraccount@example.com" can view the "TextMate 2" project
And "youraccount@example.com" has created a ticket for this project:
| title | description |
| Release date | TBA very shortly. |
Here’s another place where youraccount@example.com should be substituted with
your real Gmail account. In these steps, you set up that alice@ticketee.com and your
email both have the “view” permission on the TextMate 2 project. After this, you need
a ticket that you’ve created so that Alice can post a comment to it and you can receive
an email notification informing you of what Alice has posted.
Now you can get to the meat of your feature: the scenario itself. In this scenario,
you want to log in as alice@ticketee.com, visit the “Release date” ticket inside the Text-
Mate 2 project, and post a comment to it. After all that’s said and done, you need to
assert that your youraccount@example.com mailbox has one new message. The code
for the scenario should therefore look like in the following listing.
