Rspec rails test devise邮件程序

Question

我试图通过rspec来测试devise邮件程序。

这里是devise_mailer_spec.rb

要求 “rails_helper”

RSpec.describe Devise::Mailer do 
    it "sends a confirmation email to correct email with custom text" do 
    user = FactoryGirl.create(:user, confirmed_at: nil) 
    confirmation_email = Devise.mailer.deliveries.last 
    expect(user.email).to eq confirmation_email.to[0] 
    expect(confirmation_email.body.to_s).to have_content 'You can confirm your account email' 
    end 
end 

不过，我得到这个错误。

Failures: 

    1) Devise::Mailer sends a confirmation email to correct email with custom text 
    Failure/Error: expect(confirmation_email.body.to_s).to have_content 'You can confirm your account email' 

     expected <p>Welcome adolfo@schoen.io!</p> 

     <p>You can confirm your account email through the link below:</p> 

     <p><a href="http://localhost:3000/users/confirmation?confirmation_token=sPMPQRe5SLDPgpakVy3J">Confirm my account</a></p> 
     to respond to `has_content?` 
    # ./spec/mailers/devise_mailer_spec.rb:9:in `block (2 levels) in <top (required)>' 

Finished in 8 minutes 38 seconds (files took 5.02 seconds to load) 
2 examples, 1 failure 

Failed examples: 

rspec ./spec/mailers/devise_mailer_spec.rb:4 # Devise::Mailer sends a confirmation email to correct email with custom text 

我设置binding.pry成代码，我可以确保confirmation_email.body.to_s将抛出

"<p>Welcome edgardo@heidenreich.name!</p>\n\n<p>You can confirm your account email through the link below:</p>\n\n<p><a href=\"http://localhost:3000/users/confirmation?confirmation_token=_qi3a9rsucm6YhG8CUjt\">Confirm my account</a></p>\n" 

Answer 1

尝试：

expect(confirmation_email.body.encoded).to include 'You can confirm your account email'
