Email_spec causes rspec to fail (though not under Spring)

[davidham]

I installed email_spec per the instructions, but when I run rspec it fails with the following message:

This is from my spec_helper.rb:

require 'action_mailer'
require 'email_spec'
require 'email_spec/rspec'

When I comment out the email_spec lines, Rspec runs again.

Strange thing though: when I run Rspec under Spring with bin/rspec, I don't see this issue. Any ideas why?

[michaelrshannon]

@davidham I'm also seeing this under Rails 5 - did you have any luck solving this?

[davidham]

@michaelrshannon I'm afraid not, after trying many different things I had to uninstall it. I'm having a hard time with my email-related integration tests generally. I have a feature spec that is supposed to verify (among other things) that an email was sent, but the spec fails intermittently.

[sergiopantoja]

@davidham @michaelrshannon Here's the fix. I was running into the same problem and finally traced it down.

In your rails_helper.rb, you need to require spec_helper after loading the environment. So change this:

require 'spec_helper'
require File.expand_path('../../config/environment', __FILE__)

to this:

require File.expand_path('../../config/environment', __FILE__)
require 'spec_helper'

It's safe to do this, and in fact this is how RSpec generates the rails_helper.rb file by default now anyways (see rspec/rspec-rails@b913f6a for reference).

@sergiopantoja This is awesome, thanks for posting this! I wanted to use email-spec and I still have it commented out in my Gemfile, but I'll definitely give this a try.

👍 I am still getting this error with the proposed fix above in Rails 5.0.0
