有没有人知道如何在rspec中检查无效的枚举响应?我可以检查以确保枚举不是没有错误,但是当我检查确保坏的枚举值不起作用时,我收到错误。这些是两个规格:
it 'is not valid without question type' do
expect(build(:question, question_type: nil)).to have(1).errors_on(:question_type)
end
it 'is not valid with a bad question type' do
expect(build(:question, question_type: :telepathy)).to have(1).errors_on(:question_type)
end
这就是我的模型:
class Question < ActiveRecord::Base
enum question_type: [ :multiple_choice ]
validates :question_type, presence: true
end
这是错误:
Failure/Error: expect(build(:question, question_type: :telepathy)).to have(1).errors_on(:question_type)
ArgumentError:
'telepathy' is not a valid question_type
这是我的工厂:
FactoryGirl.define do
factory :question, :class => 'Question' do
question_type :multiple_choice
end
end
感谢您的帮助!

您的问题是您需要执行构建作为proc来评估结果。通过将括号更改为花括号来执行此操作,如https://stackoverflow.com/a/21568225/1935918
中所述it 'is not valid with a bad question type' do
expect { build(:question, question_type: :telepathy) }
.to raise_error(ArgumentError)
.with_message(/is not a valid question_type/)
end
