ruby-on-rails - Ruby 中的模型测试

Question

我在使用 ruby​​ 进行模型测试时遇到了一些问题。当我尝试使用验证测​​试时，测试会产生错误。我创建了一个具有以下验证的新模型(子模型)

 class Child < ApplicationRecord

   has_many :relations, :dependent => :destroy
   accepts_nested_attributes_for :relations
   belongs_to :user
   validates :user, presence: true
   validates :name, presence: true, length: { maximum: 50 }
   validates :city, presence: true, :on => :create
     validates :postalcode, presence: true, numericality: true
       validates :streed, presence: true
         validates :add_number, presence: true

 validates :disability, presence:true, inclusion: { in: [true, false] }
 validates :halal, presence:true, inclusion: { in: [true, false] }
 validates :koscha, presence:true, inclusion: { in: [true, false] }
 validates :vegetarian, presence:true, inclusion: { in: [true, false] }
 validates :vegan, presence:true, inclusion: { in: [true, false] }
 validates :allday, presence:true, inclusion: { in: [true, false] }

 validates :gender, presence: true

我想测试我的模型并想首先测试 child 的验证:

   def setup
     @child = Child.new(name: "Example Child", city: "Example City", postalcode: 13, streed: "Example Street",
                  add_number: 3, disability: true, gender: 1, halal: true, koscha: false,
                   vegetarian: false, vegan: false, allday:true, user: "hallo")
   end

    test "should be valid" do
      assert @child.valid?
    end

我为 children 准备的装置是这样的:

 one:
   name: MyString
   city: MyString
   postalcode: 1
   streed: MyString
   add_number: 1
   disability: false
   halal: false
   koscha: false
   vegetarian: false
   vegan: false
   allday: false
   gender: 1
   user_id: 3

我遇到了问题，我的验证测试产生了以下错误 false to be truth 而我看不到，我做错了什么......我认为，这是一个非常简单的错误......感谢您的帮助!

Answer 1

my validation test produces the following error false to be truth and I can't see, what I've done wrong

这意味着 @child.valid? 返回 false。不是 assert 所期望的。

我也不明白你做错了什么。最有可能的是，某些验证失败。找出哪个是微不足道的。只需检查 @child.errors。例如，像这样。

test "should be valid" do
  is_valid = @child.valid? # trigger validation
  p @child.errors unless is_valid

  assert is_valid
end

我赌这个:

user: "hallo"

这看起来不像是有效的用户对象。
