[rspec-users] rspec not loading rails files- uninitialized constant error

[Samantha John]

I am new to rspec. I followed a few tutorials and set it up to test my
existing rails project. I ran the rspec generators and created
spec/user_spec.rb to test my user.rb model.

The user.rb file starts with:

class User < ActiveRecord::Base

The user_spec.rb file starts with:

describe User do

When I run the test (using rake spec, bundle exec autotest, rspec
spec/user_spec.rb )
I get the error:

`const_missing': uninitialized constant User (NameError)

within the following trace:

I tried a sample app (http://relishapp.com/rspec/file/twominutetutorial)
which worked fine. I suspect that the issue is that rspec is not loading
up the files from my rails project. Which configurations do I need to
fix for this to work?

Thanks!

Hi Samantha, since you're using Rails, you'll need to run the "rspec
rails installer". Take a look at the "Configure" section on this page:
http://relishapp.com/rspec/rspec-rails

Let us know if that works.

Welcome!

When you run the rspec:install generator, it creates a spec/spec_helper.rb file that loads the Rails environment. This file needs to be required from your user_spec.rb file, which should be spec/models/user_spec.rb, not spec/user_spec.rb.

HTH,
David

Thanks David, this was exactly what I needed.
Per your advice I have moved user_spec.rb to the model, I was
experimenting with moving it around to see if that would change
anything.
Thanks again, rspec is a really nice piece of software.
