If you want to write system tests you'll probably want to cover a use-case involving an email sent to a user (for instance, a sign up confirmation link).
There are at least 2 ways to do that:
- with nokogiri if you want to keep things lean
- with capybara-email if you appreciate a little comfort
With nokogiri
Add the gem to your Gemfile
and run bundle install
.
Chances are you'll find it in your Gemfile.lock already since it's a pretty standard gem with 5k+ stars.
group :test do
gem "nokogiri"
end
And you can open your email and click the line like this:
email = ActionMailer::Base.deliveries.last
html = Nokogiri::HTML(email.html_part.body.to_s)
target_link = html.at("a:contains('Click this link')")
visit target_link["href"]
With capybara-email gem
Add the gem to your Gemfile
and run bundle install
. It only has 300+ stars, which is still pretty good, and it's also a rather simple gem so you could easily decide to contribute to it if your app depended on it.
group :test do
gem "capybara-email"
end
And you can open your email with just 2 lines:
open_email "arnaud@example.com"
current_email.click_link "Click this link"
