Question

在测试模型字段的有效性之前，我尝试在主题中设置实例变量。我需要设置此变量，因为验证是有条件的（它仅用于某些类型的用户）。所以我有这样的事情：

  context "as a user" do

    before(:each) do
      subject = Organization.new
      subject.editor = "user"
    end

    it { subject.should validate_presence_of :name }

  end

但它没有按预期工作：

 Failure/Error: it { subject.should validate_presence_of :description }
 RuntimeError:
   Organization#editor attr is not set

我错过了什么？

前块中的

subject是局部变量。您似乎打算使用an explicit subject：

context "as a user" do
  subject { Organization.new }

  before(:each) do
    subject.editor = "user"
  end

  # usually, you don't explicitly name the subject in an `it` like this
  it { should validate_presence_of :name }

end

之前是Shoulda和RSpec
