- [![Build Status](https://secure.travis-ci.org/email-spec/email-spec.svg)](http://travis-ci.org/email-spec/email-spec)
- ## Email Spec
- A collection of matchers for `RSpec`, `MiniTest` and `Cucumber` steps to make testing emails go smoothly.
- This library works with `ActionMailer` and `Pony`. When using it with ActionMailer it works with ActiveRecord Mailer, and [action_mailer_cache_delivery](https://rubygems.org/gems/action_mailer_cache_delivery).
- If you are testing emails in conjunction with an automated browser solution, like Selenium,
- you will want to use [action_mailer_cache_delivery](http://rubygems.org/gems/action_mailer_cache_delivery) in your test environment. (This is
- because your test process and server processes are distinct and therefore need an
- intermediate store for the emails.) ActiveRecord Mailer will also work but
- you generally don't want to include those projects unless you need them in production.
- ### Gem Setup
- ```ruby
- # Gemfile
- group :test do
- gem 'email_spec'
- end
- ```
- ### Cucumber
- To use the steps in features put the following in your env.rb:
- ```ruby
- # Make sure this require is after you require cucumber/rails/world.
- require 'email_spec' # add this line if you use spork
- require 'email_spec/cucumber'
- ```
- This will load all the helpers that the steps rely on. It will also add a `Before` hook for `Cucumber` so that emails are cleared at the start of each scenario.
- Then:
- ```bash
- rails generate email_spec:steps
- ```
- This will give you a bunch of steps to get started with in `step_definitions/email_steps.rb`
- By default, the generated file will look for email to example@example.com. You can either change this by editing the `current_email_address` method in `email_steps.rb`, or by simply specifying the target email in your features:
- ```gherkin
- Scenario: A new person signs up
- Given I am at "/"
- When I fill in "Email" with "quentin@example.com"
- And I press "Sign up"
- Then "quentin@example.com" should receive an email # Specify who should receive the email
- ```
- ### Spinach
- To use the helpers and matchers in your Spinach steps, add this to your env.rb:
- ```ruby
- require 'email_spec/spinach'
- ```
- Creating shared steps (as for Cucumber above) doesn't fit so well with the Spinach ethos of very compartmentalized steps, so there is no generator for Spinach. It's easy to use the helpers/matchers in your steps. For example:
- ```ruby
- step 'the last email sent should welcome the user' do
- expect(last_email_sent).to have_subject('Welcome')
- end
- ```
- ### RSpec (3.1+)
- First you need to require `email_spec` in your `spec_helper.rb`:
- ```ruby
- require "email_spec"
- require "email_spec/rspec"
- ```
- This will load all the helpers that the scenarios can count on. It will also add a `before(:each)` hook so that emails are cleared at the start of each scenario.
- If you are upgrading to Rails 5, make sure your `rails_helper.rb` requires `spec_helper` **after** loading the environment. For example:
- ```ruby
- require File.expand_path('../../config/environment', __FILE__)
- require 'spec_helper'
- ```
- ### MiniTest
- First you need to require minitest-matchers and email_spec in your test_helper.rb:
- ```ruby
- require "minitest-matchers"
- require "email_spec"
- ```
- You will then need to include EmailSpec::Helpers and EmailSpec::Matchers in your test classes.
- If you want to have access to the helpers and matchers in all of your tests you can do the following in your test_helper.rb:
- ```ruby
- class MiniTest::Unit::TestCase
- include EmailSpec::Helpers
- include EmailSpec::Matchers
- end
- ```
- Otherwise, you will need to include them in the tests where you use them:
- ```ruby
- class SignupMailerTest < MiniTest::Unit::TestCase
- include EmailSpec::Helpers
- include EmailSpec::Matchers
- ...
- end
- ```
- Or, if you are using the MiniTest spec DSL, it would look like this:
- ```ruby
- describe SignupMailer do
- include EmailSpec::Helpers
- include EmailSpec::Matchers
- ...
- end
- ```
- ### Turnip
- If you're using [Turnip](https://github.com/jnicklas/turnip), you might be interested in this [conversion of the Cucumber steps into Turnip steps](https://github.com/jmuheim/base/blob/7708873e77165993c2c962894c756621be1b15cc/spec/steps/email_steps.rb).
- ## Background Jobs
- If you are using a background job, you might need to use a step to process the jobs. Another alternative is to use an inline statement for your scenario.
- For example, for DelayedJob:
- ```ruby
- Delayed::Worker.delay_jobs = false
- ```
- ## Usage
- ### Cucumber
- ```gherkin
- Scenario: A new person signs up
- Given I am at "/"
- When I fill in "Email" with "quentin@example.com"
- And I press "Sign up"
- And I should receive an email
- When I open the email
- Then I should see "confirm" in the email body
- When I follow "confirm" in the email
- Then I should see "Confirm your new account"
- ```
- For more examples, check out examples/rails_root in the source for a small example app that implements these steps.
- ### Cucumber Matchers (Ruby)
- See RSpec Matchers (they are the same)
- ### RSpec
- #### Testing In Isolation
- It is often useful to test your mailers in isolation. You can accomplish this by using mocks to verify that the mailer is being called in the correct place and then write focused examples for the actual mailer. This is a simple example from the sample app found in the gem:
- Verify that the mailer is used correctly in the controller (this would apply to a model as well):
- ```ruby
- describe "POST /signup (#signup)" do
- it "should deliver the signup email" do
- # expect
- expect(UserMailer).to(receive(:deliver_signup).with("email@example.com", "Jimmy Bean"))
- # when
- post :signup, "Email" => "email@example.com", "Name" => "Jimmy Bean"
- end
- end
- ```
- Examples for the #signup method in UserMailer:
- ```ruby
- describe "Signup Email" do
- include EmailSpec::Helpers
- include EmailSpec::Matchers
- # include ActionController::UrlWriter - old rails
- include Rails.application.routes.url_helpers
- before(:all) do
- @email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- end
- it "should be set to be delivered to the email passed in" do
- expect(@email).to deliver_to("jojo@yahoo.com")
- end
- it "should contain the user's message in the mail body" do
- expect(@email).to have_body_text(/Jojo Binks/)
- end
- it "should contain a link to the confirmation link" do
- expect(@email).to have_body_text(/#{confirm_account_url}/)
- end
- it "should have the correct subject" do
- expect(@email).to have_subject(/Account confirmation/)
- end
- end
- ```
- #### RSpec Matchers
- ##### reply_to(email)
- alias: `have_reply_to`
- This checks that the Reply-To header's email address (the bob@example.com of
- "Bob Saget <bob@example.com>") is set to the given string.
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- expect(email).to reply_to("support@myapp.com")
- ```
- ##### deliver_to(\*email_addresses)
- alias: `be_delivered_to`
- This checks that the To header's email addresses (the bob@example.com of
- "Bob Saget <bob@example.com>") are set to the addresses.
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- expect(email).to deliver_to("jojo@yahoo.com")
- ```
- ##### deliver_from(email)
- alias: `be_delivered_from`
- This checks that the From header's email address (the bob@example.com of
- "Bob Saget <bob@example.com>") is set to the given string.
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- expect(email).to deliver_from("sally@yahoo.com")
- ```
- ##### bcc_to(\*email_addresses)
- This checks that the BCC header's email addresses (the bob@example.com of
- "Bob Saget <bob@example.com>") are set to the addresses.
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- expect(email).to bcc_to("sue@yahoo.com", "bill@yahoo.com")
- ```
- ##### cc_to(\*email_addresses)
- This checks that the CC header's email addresses (the bob@example.com of
- "Bob Saget <bob@example.com>") are set to the addresses.
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- expect(email).to cc_to("sue@yahoo.com", "bill@yahoo.com")
- ```
- ##### have_subject(subject)
- This checks that the Subject header's value is set to the given subject.
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- expect(email).to have_subject("Welcome!")
- ```
- ##### include_email_with_subject(subject)
- Note: subject can be either a String or a Regexp
- This checks that one of the given emails' subjects includes the subject.
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- email2 = UserMailer.forgot_password("jojo@yahoo.com", "Jojo Binks")
- expect([email, email2]).to include_email_with_subject("Welcome!")
- ```
- ##### have_body_text(text)
- Note: text can be either a String or a Regexp
- This checks that the text of the body has the given body.
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- expect(email).to have_body_text(/Hi Jojo Binks,/)
- ```
- ##### have_header(key, value)
- This checks that the expected key/value pair is in the headers of the email.
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- expect(email).to have_header("X-Campaign", "1234abc")
- ```
- #### Using the helpers when not testing in isolation
- Don't. :) Seriously, if you do just take a look at the helpers and use them as you wish.
- ### MiniTest
- You will use EmailSpec in your tests the same way you use it in your specs. The only difference is the use of MiniTest's `must` instead of Rspec's `should`:
- ```ruby
- email = UserMailer.create_signup("jojo@yahoo.com", "Jojo Binks")
- email.must deliver_to("jojo@yahoo.com")
- ```
- Or, you can use the matcher as an expectation:
- ```ruby
- email = UserMailer.create_signup "jojo@yahoo.com", "Jojo Binks"
- email.must_deliver_to "jojo@yahoo.com"
- ```
- And of course you can use the matcher as an assertion:
- ```ruby
- email = UserMailer.create_signup "jojo@yahoo.com", "Jojo Binks"
- assert_must deliver_to("jojo@yahoo.com"), email
- ```
