rspec - 无法使用RSpec 2和Edge Rails 3进行 Controller 测试

Question

不知道这是Rails 3还是RSpec 2，但是我似乎无法使标准 Controller 测试正常-似乎找不到'get'方法。

我有一个看起来像这样的 Controller 测试(在discrepancies_controller_spec.rb目录中名为spec/controllers):

require 'spec_helper'

describe DiscrepanciesController do
  before :each do
    Discrepancy.delete_all
  end

  it "resolves a discrepancy" do
 discrepancy = Discrepancy.create(:my_number=>"12345", :status=>"Open")

 get :resolve, :id => discrepancy.id

 retrieved_discrepancy = Discrepancy.find_by_my_number("12345")
 retrieved_discrepancy.status.should == "Resolved"
  end
end

(是的，我知道使用HTTP/GET修改数据的安全性-这是一个单独的问题...)

当我用rake运行它时，出现以下错误:

1) DiscrepanciesController resolves a discrepanc
    Failure/Error: Unable to find C to read failed line
    undefined method `get' for #<RSpec::Core::ExampleGroup::Nested_1:0xc9170d0 @__memoized={}>
    # ./spec/controllers/discrepancies_controller_spec.rb:38 (ignore the line number, commented out code was removed from the sample)
    # C:/Users/Patrick_Gannon/.bundle/ruby/1.8/bundler/gems/rails-16a5e918a06649ffac24fd5873b875daf66212ad-master/activesupport/lib/active_support/dependencies.rb:212:in `inject'
    # C:/Ruby187/bin/rake:19:in `load'
    # C:/Ruby187/bin/rake:19

我可以通过自己实例化 Controller 并直接调用 Controller Action 来测试 Controller Action ，它可以工作，但是很难看，因为我必须模拟出respond_to和params之类的东西。

Answer 1

可以从David Chelimsky的RSpec邮件列表中获得有关此问题的答案，如下所示:

我很惊讶这是它第一次提出rspec-2，但是我们在这里:)

这是一个路径分隔符错误，我将在下一版本中解决。现在，您可以在 Controller 规范中执行此操作:

describe DiscrepanciesController do
  include RSpec::Rails::ControllerExampleGroup

那应该工作正常。

如果要执行更全局的解决方法，请将其添加到您的spec_helper配置中:

RSpec.configure do |c|
  c.include RSpec::Rails::ControllerExampleGroup, :example_group => { :file_path => /\bspec[\\\/]controllers[\\\/]/ }
end
