Question

I’m currently testing my mailers with RSpec, but I’ve started setting up multipart emails as described in the Rails Guides here: http://guides.rubyonrails.org/action_mailer_basics.html#sending-multipart-emails

I have both mailer templates in text and html formats, but it looks like my tests are only checking the HTML portion. Is there a way to check the text template separately?

Is it only checking the HTML view because it’s first in the default order?

Answer 1

This can be tested with regular expressions.

Finding things in the HTML portion (use #should after this to match):

mail.body.parts.find {|p| p.content_type.match /html/}.body.raw_source

Finding things in the plain text portion (use #should after this to match):

mail.body.parts.find {|p| p.content_type.match /plain/}.body.raw_source

Checking that it is, indeed, generating a multipart message:

it "generates a multipart message (plain text and html)" do
  mail.body.parts.length.should == 2
  mail.body.parts.collect(&:content_type).should == ["text/html; charset=UTF-8", "text/plain; charset=UTF-8"]
end
