"Cannot autoload constants" using rspec but not rails

Question

I have this file that I would like to check.

app/workers/station/http.rb

module Worker
  module Station
    class HTTP
      # ...
    end
  end
end

This is my spec file.

spec/workers/station/http_spec.rb

describe Worker::Station::HTTP do
  it "should do something"  do
  end 
end

Now the problem is that I get the following error when running the spec file using rspec.

rspec spec/workers/station/http_spec.rb

The strange thing is that everyting is running on the console.

$ rails c [1] pry(main)> Worker::Station::HTTP => Worker::Station::HTTP

Why is this happening using rspec and not on rails and how can I fix it?

I use

• rails (4.0.4)
• rspec (2.14.1)

Answer 1

The path app/workersdoes not start rspec, since it is not a standard rail layout, you can add an autoload line to your spec_helper or directly request the file in the specification!

Answer 2

jfornoff, require , :

require "app/workers/station/http"

Spring Rails, , , Spring. Spring :

bundle exec rspec spec/workers/station/http_spec.rb

... ...

spring stop # or bin/spring stop
rspec spec/workers/station/http_spec.rb
