CapybaraEmail

Build Status

Easily test ActionMailer and Mail messages in your Capybara integration tests

Installation

Add this line to your application's Gemfile:

gem 'capybara-email'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capybara-email

Usage

RSpec

Require capybara/email/rspec in your spec_helper

Example:

feature 'Emailer' do
  background do
    # will clear the message queue
    clear_emails
    visit email_trigger_path
    # Will find an email sent to test@example.com
    # and set `current_email`
    open_email('test@example.com')
  end

  scenario 'following a link' do
    current_email.click_link 'your profile'
    page.should have_content 'Profile page'
  end

  scenario 'testing for content' do
    current_email.should have_content 'Hello Joe!'
  end

  scenario 'view the email body in your browser' do
    # the `launchy` gem is required
    current_email.save_and_open
  end
end

Cucumber

Require capybara/email in your features/support/env.rb

require 'capybara/email'

Once you have required capybara-email, gaining access to usable methods is easy as adding this module to your Cucumber World:

World(Capybara::Email::DSL)

I recommend adding this to a support file such as features/support/capybara_email.rb

require 'capybara/email'
World(Capybara::Email::DSL)

Example:

Scenario: Email is sent to winning user
  Given "me@example.com" is playing a game
  When that user picks a winning piece
  Then "me@example.com" receives an email with "You've Won!" as the subject

Then /^"([^"]*)" receives an email with "([^"]*)" as the subject$/ do |email_address, subject|
  open_email(email_address)
  current_email.subject.should eq subject
end

Test::Unit

Include Capybara::Email::DSL in your test class

class ActionController::IntegrationTest
  include Capybara::Email::DSL
end

Example:

class EmailTriggerControllerTest < ActionController::IntegrationTest
  def setup
    # will clear the message queue
    clear_emails
    visit email_trigger_path

    # Will find an email sent to `test@example.com`
    # and set `current_email`
    open_email('test@example.com')
  end

  test 'following a link' do
    current_email.click_link 'your profile'
    page.should have_content 'Profile page'
  end

  test 'testing for content' do
    current_email.should have_content 'Hello Joe!'
  end

  test 'view the email body in your browser' do
    # the `launchy` gem is required
    current_email.save_and_open
  end
end
