ruby-on-rails-3 - 升级到 RSpec 2 : errors replaced with have(n). errors_on？需要解决方法

Question

这是我的 rspec 1.x 代码中的一些示例测试:

[:email, :contact_type_id].each do |attr|
  it "requires #{attr}" do
    e = EmailAddress.new
    e.should_not be_valid
    # i don't care how many errors there are,
    # just that there were errors for this attr.
    e.errors(attr).should_not be_nil
  end
end

RSpec 2.6.x 迫使我这样做:

[:email, :contact_type_id].each do |attr|
  it "requires #{attr}" do
    e = EmailAddress.new
    e.should_not be_valid
    # have expects that I pass a number here :(
    e.should have(n).error_on(attr)
  end
end

我不关心有多少错误，只关心在尝试验证模型时出现的错误。如果我能做类似的事情会很酷:

e.should have.errors_on(attr)

有人有什么想法吗？

Answer 1

你可以试试这个:

e.should have_at_least(1).error_on(attr)
