Question

# /spec/presenters/pdf_download_spec.rb

  describe "instance methods" do
    let(:survey) { Survey.create :title => "test survey" }
    let(:pdf_download) { PdfDownload.new survey }
    before do
      # only write to tmp folders
      PdfDownload.any_instance.stub(:location_prefix) { '../tmp' }
    end

    it "should stub location prefix properly" do
      pdf_download.system_path.should_not be_empty
      pdf_download.system_path.should be_include File.join(Rails.root, 'tmp')
      pdf_download.system_path.should be_start_with File.join(Rails.root, 'tmp')
    end
  end

# app/models/pdf_download.rb

  def system_path
    File.expand_path File.join Rails.root, "public", location_path
  end

失败讯息：

  1) PdfDownload instance methods should stub location prefix properly
     Failure/Error: expect(pdf_download.system_path).to be_empty
     NameError:
       undefined local variable or method `be_empty' for #<#<Class:0x007f8af0924870>:0x007f8af1b82a08>
     # ./spec/presenters/pdf_download_spec.rb:36:in `block (3 levels) in <top (required)>'

为什么rspec不会将be_include或be_start_with识别为here所述的有效方法？这可能是显而易见的事情，在这种情况下我道歉。我有rspec 2.12.2。谢谢！

更新：我在rspec-expectations 2.12中意识到，start_with和include是内置的匹配器，因此我不需要（实际上我不能）将它们作为be_加上前缀。这解决了上述3次失败中的2次。但根据文档should still work，should_not be_empty仍然会导致失败。

Answer 1

be_include不是匹配器或查找器。我想，您想检查一下，如果您的文件路径是否正确，请执行以下操作：

pdf_download.system_path.should eql(File.join(Rails.root, 'tmp'))

你可以使用像这样的包含，但我认为它不会起作用。你应该这样做： -

pdf_download.system_path.should include File.join(Rails.root, 'tmp')

或

由于

rspec失败了'未定义的方法`be_include'for Class'
