Question

I’m trying to use Rspec 1.3.1 for my rails application which is running on 2.3.8. I am able to ‘stub’ the models with stub_model method. But when I call mock_model, things go wrong and this is the stack trace I get

./spec/models/bucket_spec.rb:32: undefined method `mock_model' for Spec::Rails::Example::ModelExampleGroup::Subclass_2:Class (NoMethodError)

The bucket_spec.rb file:

  require 'spec_helper'
   describe Bucket, "creation" do
  before(:each) do
    @bucket = stub_model(Bucket, :id => 1, :name => "Below Proficient", :color =>     "green", :min_range => 0, :max_range => 30, :class_group_id => 1).as_new_record
  end
  it "should be valid with all the attributes set to some randowm values" do
    @bucket.should be_valid
  end
  it "should be valid without min_range" do
    @bucket.min_range = nil
    @bucket.should be_valid
   end
  it "should be valid without max_range" do
    @bucket.max_range = nil
    @bucket.should be_valid
  end
  it "should be valid without class_group_id" do
    @bucket.class_group_id = nil
    @bucket.should be_valid
  end
  it "should not be valid without color" do
    @bucket.color = nil
    @bucket.should_not be_valid
  end
  it "should not be valid without name" do
    @bucket.name = nil
    @bucket.should_not be_valid
  end
end

describe Bucket, "saving" do
  @bucket = mock_model(Bucket)
  @bucket.should be_valid
end

The spec_helper.rb file:

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'spec/rails'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
#
#RSpec.configure do |config|
#  # == Mock Framework
#  #
#  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
#  #
#  # config.mock_with :mocha
#  # config.mock_with :flexmock
#  # config.mock_with :rr
#  config.mock_with :rspec
#
#  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
#  config.fixture_path = "#{::Rails.root}/spec/fixtures"
#
#  # If you're not using ActiveRecord, or you'd prefer not to run each of your
#  # examples within a transaction, remove the following line or assign false
#  # instead of true.
#  config.use_transactional_fixtures = true
#end
Spec::Runner.configure do |config|
  config.mock_with :rspec
  config.use_transactional_fixtures = true
end

Your call to mock_model is at the top level of your describe block which doesn’t make sense

You can only do that inside a before(:each), an example (ie in the block passed to it) and places like that
