我正在尝试使用mpecoid的rspec,但我遇到了这个错误：
undefined method `should_receive' for ShortenedUrl:Class
这是我的spec_helper.rb文件：
# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment",__FILE__)
require 'rspec/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
config.before(:each) do
Mongoid.master.collections.each(&:drop)
end
end
这是我的测试文件：
require 'spec_helper'
describe UrlsController do
describe "POST make_short" do
context "when posting a valid url" do
# url = mock('ShortenedUrl')
url = Struct.new('ShortenedUrl')
ShortenedUrl.should_receive(:new).with(:url => 'http://example.com').and_return(url)
url.should_receive(:save!)
post :make_short,:url => 'http://example.com'
end
end
end
最后,这是Gemfile：
source 'http://rubygems.org' gem 'rails','3.0.3' gem "mongoid",">= 2.0.0.beta.19" gem "rspec-rails",">= 2.0.1",:group => [:development,:test] gem "cucumber-rails",:group => :test gem "capybara",:group => :test
根据我的理解,如果我没有使用rspec模拟,我应该得到这个错误,但在我的情况下,我正在使用它.有任何想法吗？
解决方法
您的测试需要在示例中或阻止(它们是相同的方法)：
it "when posting a valid url" do
# url = mock('ShortenedUrl')
url = Struct.new('ShortenedUrl')
ShortenedUrl.should_receive(:new).with(:url => 'http://example.com').and_return(url)
url.should_receive(:save!)
post :make_short,:url => 'http://example.com'
end
上下文块用于对类似示例进行分组.
