A custom html-proofer test that makes your mailto: links awesome.

We should use awesome links as psychological warfare against users. Users will send us emails with stupid or annoying content that we don't want. At big companies (like Amazon) they have abandoned email altogether because of this reason. So instead we prefill the email with the message we want to receive. It takes active cognitive effort for the user to put in their unwanted message.

❌ For example, this is a not-awesome mailto link:

<a href="mailto:support@pacificmedicaltraining.com">Email us</a>

✅ This is an awesome link:

<a href="mailto:support@pacificmedicaltraining.com?subject=Signing up&amp;body=Hello,\nI'd like to sign up for your course, can you please send me more information.">Email us</a>

Follow the same instructions as for any html-proofer custom class.

Our ruby gem is html-proofer-mailto_awesome

1. Add new dependency to your Ruby project

   In Gemfile:

     gem 'html-proofer-mailto_awesome'
   

   Or in your .gemspec:

     Gem::Specification.new do |s|
         ...
         s.add_runtime_dependency 'html-proofer-mailto_awesome'
     end
   

2. Create a Rakefile like the following and add it to your project

   task :default => [:test]
   desc 'run Rspec specs'
   task :test do
     sh 'rspec spec'
   end
   

3. Run bundle install

4. Run rake

Also if you like, you can enable your project for continuous integration testing with Travis:

1. Set up Travis CI for your project

2. Add a .travis.yml file like the following to your project and your spec will run automatically

   language: ruby
   rvm:
     - 2.5.3       
   

For additional tests you can run on your website, see Lightning Sites and for a sample GitHub project that implements this testing and follows many other HTML development best practices, see HTML Website Template.
