application through rails server. But how do you ensure that it works all the time?
The feature will provide that insurance.
When you’re done here, you’ll have your application hooked up to Gmail’s SMTP
server so that you can send emails in the real world, and you’ll have a Cucumber feature
to ensure that it’s never broken. 9 Let’s jump into it.
12.3.1 Testing real-world email
In this section, you’ll create a feature in which you set up Action Mailer to send out
emails to Gmail’s SMTP service. You’ll then update a ticket’s comment, which should
trigger the emails to be sent to the real world. Finally, you’ll check the Gmail account
(using the mail gem on which Action Mailer is based), to make sure that the email
was received. If it wasn’t received, then the cause is most likely a configuration problem,
such as an invalid password.
Let’s write this new feature in a new file called features/gmail.feature a bit at a time.
You start with just these few lines:
Feature: Gmail
In order to send real world emails
As the application
I want to ensure my configuration is correct
Background:
Given there are the following users:
| email | password |
| alice@ticketee.com | password |
| youraccount@example.com | password |
And Action Mailer delivers via SMTP
Here you have the standard feature setup on the first four lines, describing to any
interested reader what this feature’s purpose is. The final few lines begin your feature’s
Background, defining two users that you’ll use and an as-of-yet undefined step.
The two users set up here are for setting up the ticket a little later on in your Background.
The youraccount@example.com should be your actual Gmail account’s
address 10 for reasons that you’ll see later. 11
The current undefined step on the final line will be used to tell Action Mailer not
to capture all emails that are being sent, but rather to send them out through the
SMTP configuration that you’ll set up in a little while. When you run this feature using
bin/cucumber features/gmail.feature, you’re given the step definition for this step:
Given /^Action Mailer delivers via SMTP$/ do
pending # express the regexp above with the code you wish you had
end
9 That is to say, if you run all the tests and they all pass before you commit, then you know that your Gmail connection
would be working, too.
10 And if you don’t have one, sign up! It’s free and will only take a minute.
11 We’d use youraccount@gmail.com as the example here, but we don’t want to bombard the owner of this
actual account with emails!
