problem with rspec test, undefined method 'post'

Question

I am writing a spec to test the behavior of the mashup_controller when someone sends a query through a URL. I need to simulate the parameters contained in the URL, and i read that the post() method will do that, however when i get an error:

1) MashupController simulates query
     Failure/Error: post :create
     NoMethodError:
       undefined method `post' for
#<RSpec::Core::ExampleGroup::Nested_1:0x980bc50>
     # ./mashup_controller_rspec.rb:9:in `block (2 levels) in <top (required)>'

Finished in 0.20199 seconds 1 example, 1 failure

Failed examples:

rspec ./mashup_controller_rspec.rb:7 # MashupController simulates query

Here is my code:

require 'spec_helper'
require 'mashup_controller.rb'

describe MashupController do
    it "simulates query" do
        post :create    
    end
end

Sorry if I'm not making any sense. I am very new to rails and rspec. Any help would be appreciated. Thanks.

Show your directory structure. Also, what rails version are you using? Does this mashup controller inherits from ApplicationController? — Maurício Linhares, Aug 21 '11 at 03:09
yeah, MashupController does inherit from ApplicationController. mashup_controller.rb is in another directory, but I added it to $LOAD_PATH, so i dont think that is the problem. Also, I am running Ruby 1.9.2, Rails 3.0.1, and rspec-rails 2.6.1. I am wondering if i just set something up wrong. — user727403, Aug 21 '11 at 19:28

If the spec file is not under spec/controllers, methods like get and post will not be automatically made available by rspec-rails.

You either need to tag your spec:

describe MyController, type: :controller do
  # ...
end

or include the module:

describe MyController do
  include RSpec::Rails::ControllerExampleGroup
  # ...
end

See the relevant code in rspec-rails.

Make sure you have gem spec-rails in your Gemfile
Your mashup_controller_rspec.rb should be under spec/controllers

Your tests can also be under spec/requests and they will be able to post, etc. – Kage Aug 13 '13 at 23:53

I used gem rspec-rails instead of gem spec-rails.

In Rails 4, you can declare the type of the RSpec tests as :request and the spec file can be in any directory.

example: in spec/routes/users.rb
RSpec.describe 'UserRoutes', type: :request do
  ...
end
