告诉rspec（核心）测试正在测试控制器

Question

Trying to run this test but keep getting the following error:

Failure/Error: get :index

 NoMethodError:
   undefined method `get' for #<RSpec::ExampleGroups::TestModuleTestController::Controller:0x007fa4bc120d00>

Note: I'm not using rspec-rails.

require "spec_helper"

module TestModule
  describe TestController, :type => :controller do
    describe "controller" do
      it "sets X-Frame-Options to ALLOWALL" do
        get :index
        expect(response.headers['X-Frame-Options']).to eq('ALLOWALL')
      end
    end
  end
end

Note: I'm not using rspec-rails.

That's your problem right there. All the rails type specs (controller, request, features, views) are part of rspec-rails not rspec-core.

Without rspec-rails the type metadata does absolutely nothing - its just a plain example group describing a class.

The solution is to add rspec-rails to your gemfile.

group :development, :test do
  gem 'rspec-rails', '~> 3.6'
end

And run rails g rspec install .
