ruby-on-rails - cucumber 未定义方法

Question

我正在使用 cucumber与 capybara
我有几个类似的错误。

对于步骤:

Then /I should see movies of rating 'PG' or 'R'/ do
  page.body.should match(/<td>PG<\/td>/)
  page.body.should match(/<td>R<\/td>/)
end

cucumber 错误:

undefined method `match' for #<Cucumber::Rails::World:...> (NoMethodError)
./features/step_definitions/movie_steps.rb:37:in 
   `/I should see movies of rating 'PG' or 'R'/'

对于步骤:

Then /I should see an empty table/ do
  page.body.scan(/<tr>/).length.should == 0
end

cucumber 错误:

undefined method `should' for 1:Fixnum (NoMethodError)
./features/step_definitions/movie_steps.rb:46:in 
      `/I should see an empty table/'

对于步骤:

Then /I should see all of the movies/ do
  Movie.find(:all).length.should page.body.scan(/<tr>/).length
end

undefined method `should' for 10:Fixnum (NoMethodError)
./features/step_definitions/movie_steps.rb:59:in 
    `/I should see all of the movies/'

整个步骤文件是 here

正如您所看到的，这些错误非常相似，但我不明白是什么导致了这个问题。

在我看来，您在 rspec 期望方面遇到了问题。尝试添加

require 'rspec/expectations'

到您的 env.rb 和等效于您的 Gemfile。
