RSpec显式标记的案例从NameError失败

Question

I'm currently using rspec-core-3.1.7 with a rails application I've inherited. It seems like the previous owners made a lot of progress with their testing suite, but I can't seem to get it working properly. My spec_helper.rb and rails_helper.rb are fresh from a rails generate rspec:install , with some minor tweaks.

The way the tests are set-up looks as follows:

require "rails_helper"

RSpec.describe FooController, :type => :routing do
  ...

and here was the relevant error message:

athan@spacerobot:~/website$ rake spec:routing
/home/athan/.rbenv/versions/2.1.2/bin/ruby -I/home/athan/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/rspec-core-3.1.7/lib:/home/athan/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/rspec-support-3.1.2/lib /home/athan/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/rspec-core-3.1.7/exe/rspec --pattern ./spec/routing/\*\*/\*_spec.rb
/home/athan/website/spec/routing/foo_routing_spec.rb:3:in `<top (required)>': uninitialized constant FooController (NameError)
    from /home/athan/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/rspec-core-3.1.7/lib/rspec/core/configuration.rb:1105:in `load'
    from /home/athan/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/rspec-core-3.1.7/lib/rspec/core/configuration.rb:1105:in `block in load_spec_files'
...

But for some reason, I can't get rspec to find FooController before it throws the NameError. Is it a common convention to... pretend these classes exist, when describing RSpec tests? Where would they come from...? How should I properly define test descriptions?

Answer 1

I am not too familiar with how rails uses rspec, but I do use rspec quite a bit for my test suites. I am suspecting that you need to add a require for the FooController into either the spec_helper.rb or rails_helper.rb. In my case, I require all of my test framework components in the spec_helper.rb so that they are available for all the tests to use. Hope that helps.
