Question

我在RSpec测试中比较两个地址对象，但即使属性看起来具有相同的值，测试也会失败。我正在使用expect(object1).to eq(object2)并收到以下输出：

Failures:

1) Property#address= sets all address fields
   Failure/Error: expect(property).to eq(property_address)

     expected: #<Property id: nil, property_type_id: nil, street: "780 Monterey Blvd", unit: "301", city: "San Francisco", state: "CA", zip: "94127", country: "US", square_feet: "906", beds: "2", baths: "1", floors: "1", created_at: nil, updated_at: nil, user_id: 348>
          got: #<Property id: nil, property_type_id: nil, street: "780 Monterey Blvd", unit: "301", city: "San Francisco", state: "CA", zip: "94127", country: "US", square_feet: "906", beds: "2", baths: "1", floors: "1", created_at: nil, updated_at: nil, user_id: 348>

     (compared using ==)

     Diff:

使用pry-rescue查看实际属性并进行比较，我会收到以下信息：

[3] pry(RSpec::Expectations)> actual.attributes
=> {"id"=>nil,
 "property_type_id"=>nil,
 "street"=>"780 Monterey Blvd",
 "unit"=>"301",
 "city"=>"San Francisco",
 "state"=>"CA",
 "zip"=>"94127",
 "country"=>"US",
 "square_feet"=>"906",
 "beds"=>"2",
 "baths"=>"1",
 "floors"=>"1",
 "created_at"=>nil,
 "updated_at"=>nil,
 "user_id"=>335}
[4] pry(RSpec::Expectations)> expected.attributes
=> {"id"=>nil,
 "property_type_id"=>nil,
 "street"=>"780 Monterey Blvd",
 "unit"=>"301",
 "city"=>"San Francisco",
 "state"=>"CA",
 "zip"=>"94127",
 "country"=>"US",
 "square_feet"=>"906",
 "beds"=>"2",
 "baths"=>"1",
 "floors"=>"1",
 "created_at"=>nil,
 "updated_at"=>nil,
 "user_id"=>335}
[5] pry(RSpec::Expectations)> differ.diff(actual.attributes, expected.attributes)
=> "\e[0m\n\e[0m"

我无法发现任何差异。 diff - 差异来自哪里？

解
我在How to test for (ActiveRecord) object equality中没有听到答案的原因是，在pry-rescue中，输出结果为 differ.diff(actual.attributes, expected.attributes)显示与实际失败规范相同的差异。但是，按照How to test for (ActiveRecord) object equality的答案，我试了一下并更改了实际规格以使用expect(property.attributes).to eq(property_address.attributes)，现在规范通过了。

比较看似相同的属性时RSpec测试失败
