RSpec和ActiveModel

我有一个模块，它包含activemodel，我想用rspec测试它。

这是我到目前为止的设置：

lib/ |__ my_module/ | |__ base.rb |__ my_module.rb spec/ |__ my_module_spec.rb |__ spec_helper.rb |__ support/ |__ shared_examples/ |__ active_model.rb 

在’my_class.rb’里面：

 require "active_model" require "my_module/base" 

在’base.rb’里面：

 module MyModule class Base extend ActiveModel::Naming include ActiveModel::Conversion include ActiveModel::Validations end end 

在’my_module_spec.rb’里面：

 require 'spec_helper' describe MyModule do describe MyModule::Base do it_behaves_like "ActiveModel" end end 

在’spec_helper.rb’里面：

 $LOAD_PATH.unshift(File.join(File.dirname(__FILE__), '..', 'lib')) $LOAD_PATH.unshift(File.dirname(__FILE__)) require 'rspec' require 'my_module' # Requires supporting files with custom matchers and macros, etc, # in ./support/ and its subdirectories. Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each {|f| require f} RSpec.configure do |config| end 

在’active_model.rb’里面：

 # taken from http://pivotallabs.com/users/jdean/blog/articles/1706-form-backing-objects-for-fun-and-profit shared_examples_for "ActiveModel" do require 'test/unit/assertions' require 'active_model/lint' include Test::Unit::Assertions include ActiveModel::Lint::Tests before do @model = subject end ActiveModel::Lint::Tests.public_instance_methods.map { |method| method.to_s }.grep(/^test/).each do |method| example(method.gsub('_', ' ')) { send method } end end 

我以为我的设置没问题，但是当我尝试运行bundle exec rspec spec我收到这些错误：

 Failures: 1) MyModule MyModule::Base behaves like ActiveModel test to key Failure/Error: example(method.gsub('_', ' ')) { send method } 2) MyModule MyModule::Base behaves like ActiveModel test to param Failure/Error: example(method.gsub('_', ' ')) { send method } 3) MyModule MyModule::Base behaves like ActiveModel test to partial path Failure/Error: example(method.gsub('_', ' ')) { send method } 4) MyModule MyModule::Base behaves like ActiveModel test valid? Failure/Error: example(method.gsub('_', ' ')) { send method } 5) MyModule MyModule::Base behaves like ActiveModel test persisted? Failure/Error: example(method.gsub('_', ' ')) { send method } 6) MyModule MyModule::Base behaves like ActiveModel test model naming Failure/Error: example(method.gsub('_', ' ')) { send method } 7) MyModule MyModule::Base behaves like ActiveModel test errors aref Failure/Error: example(method.gsub('_', ' ')) { send method } 8) MyModule MyModule::Base behaves like ActiveModel test errors full messages Failure/Error: example(method.gsub('_', ' ')) { send method } 

我在这做错了什么？ 如何正确测试ActiveModel？

你试着做太多。 因为您想要测试ActiveModel库。 如果您的对象包含此模块，您只需要测试

 require 'spec_helper' describe MyModule do describe MyModule::Base do it { MyModule::Base.should include(ActiveModel::Conversion) } it { MyModule::Base.should include(ActiveModel::Validations) } end end
