In Rails why is my mail body empty only in my test?

Question

I have an actionmailer class and associated overhead, it works perfectly. In my unit test (rails default minitest) however, the email body is empty. Why is that?

my mail

Answer 1

You probably have two versions of the email templates (text.erb and html.erb).

If so, you can use email.text_part.body.to_s for plain-text email and email.html_part.body.to_s for HTML version.
