使用 CouchRest Model 使用 RSpec 在 Rails 中测试错误

Question

I have a normal Rails project (without Active Record) using CouchDB (couchrest_model) as a document database.

I did setup RSpec and a basic scaffold 'Project'.

When I test the following spec:

  before(:each) do
    @project = Project.create! valid_attributes
  end

  describe "GET index" do
    it "assigns all projects as @projects" do
      get :index
      assigns(:projects).should eq([@project])
    end
  end

I get the following error:

Failure/Error: assigns(:projects).should eq([@project])

       expected [{"name"=>"test", 
                  "updated_at"=>2011-05-28 11:24:04 -0500,
                  "created_at"=>2011-05-28 11:24:04 -0500, 
                  "couchrest-type"=>"Project",
                  "_id"=>"709edbfaafb24fa1eff7d5f3966b2bda",
                  "_rev"=>"1-ae3f6356f8e32f6006337a4f3759bca4"}]
            got [{"name"=>"test",
                  "updated_at"=>2011-05-28 11:24:04 -0500, 
                  "created_at"=>2011-05-28 11:24:04 -0500,
                  "_id"=>"709edbfaafb24fa1eff7d5f3966b2bda",
                  "_rev"=>"1-ae3f6356f8e32f6006337a4f3759bca4",
                  "couchrest-type"=>"Project"}]

It seems that the only difference is the order of the elements in the hash:

  (compared using ==)

   Diff:

    [{"name"=>"test",
      "updated_at"=>2011-05-28 11:24:04 -0500,

   +  "_rev"=>"1-ae3f6356f8e32f6006337a4f3759bca4",
   +  "couchrest-type"=>"Project"}]

I know 'rspec' and 'rspec-rails' only work out of the box for Active Record, but it shouldn't be so different for other ORMs. Am I missing something?

Which is the best way to fix this test?

Answer 1

Try:

assigns(:projects).should == [@project]
