RSpec 1.3.3 Rails 2.3.9 Webrat 0.7.3“未定义方法`assign`”

我的规格

require 'spec_helper' describe 'user_sessions/new.html.erb' do let (:user_session) { mock_model(UserSession).as_null_object } before do assign(:user_session, user_session) end it 'should have the sign in header' do render rendered.should contain('Sign in') end end 

抛出

 1) NoMethodError in 'user_sessions/new.html.erb should have the sign in header' undefined method `assign' for # 

gem：

 group :test, :cucumber do gem "cucumber-rails", "0.3.2" gem "rspec-rails", "1.3.3" gem "database_cleaner", "0.5.0" # gem "capybara", "0.3.9" gem "webrat" gem "selenium-client", "1.2.18" gem "sqlite3-ruby", "1.3.1" gem "email_spec", "~> 0.6.3", :require => 'spec' gem "factory_girl" gem "launchy" end 

和spec_helper.rb

 # This file is copied to ~/spec when you run 'ruby script/generate rspec' # from the project root directory. ENV["RAILS_ENV"] = 'test' require File.expand_path(File.join(File.dirname(__FILE__),'..','config','environment')) require 'spec/autorun' require 'spec/rails' # Uncomment the next line to use webrat's matchers require 'webrat/integrations/rspec-rails' # Requires supporting files with custom matchers and macros, etc, # in ./support/ and its subdirectories. Dir[File.expand_path(File.join(File.dirname(__FILE__),'support','**','*.rb'))].each {|f| require f} Spec::Runner.configure do |config| # If you're not using ActiveRecord you should remove these # lines, delete config/database.yml and disable :active_record # in your config/boot.rb config.use_transactional_fixtures = true config.use_instantiated_fixtures = false config.fixture_path = RAILS_ROOT + '/spec/fixtures/' # == Fixtures # # You can declare fixtures for each example_group like this: # describe "...." do # fixtures :table_a, :table_b # # Alternatively, if you prefer to declare them only once, you can # do so right here. Just uncomment the next line and replace the fixture # names with your fixtures. # # config.global_fixtures = :table_a, :table_b # # If you declare global fixtures, be aware that they will be declared # for all of your examples, even those that don't use them. # # You can also declare which fixtures to use (for example fixtures for test/fixtures): # # config.fixture_path = RAILS_ROOT + '/spec/fixtures/' # # == Mock Framework # # RSpec uses its own mocking framework by default. 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 # # == Notes # # For more information take a look at Spec::Runner::Configuration and Spec::Runner end

这看起来像版本混乱。

RSpec2 for Rails 3的注释说

assign（key，value）用rspec-rails-1.3替换assign [key] = value

正如您在早期版本中所做的那样，您可能想要旧版本。 所以尝试改变

 assign(:user_session, user_session) 

至

 assigns[:user_session] = user_session
