Question

这是我的模特：

class Restaurant < ActiveRecord::Base
    validate :name, presence: true, uniqueness: { case_sensitive: false }
end

以下是测试：

require 'spec_helper'

describe Restaurant do
    before do
        @restaurant = Restaurant.new(name: "Momofuku")
    end

    subject { @restaurant }

    it { should respond_to(:name) }
    it { should be_valid }

    describe "when name is not present" do
        before { @restaurant.name = " " }
        it { should_not be_valid}
    end

    describe "when name is already taken" do
        before do
            restaurant_with_same_name = @restaurant.dup
            restaurant_with_same_name.name = @restaurant.name.upcase
            restaurant_with_same_name.save
        end

        it { should_not be_valid }
    end
end

当我运行测试时，我会失败：

$ bundle exec rspec spec/models
..FF

Failures:

  1) Restaurant when name is not present should not be valid
     Failure/Error: it { should_not be_valid}
       expected #<Restaurant id: nil, name: " ", created_at: nil, updated_at: nil> not to be valid
     # ./spec/models/restaurant_spec.rb:15:in `block (3 levels) in <top (required)>'

  2) Restaurant when name is already taken should not be valid
     Failure/Error: it { should_not be_valid }
       expected #<Restaurant id: nil, name: "Momofuku", created_at: nil, updated_at: nil> not to be valid
     # ./spec/models/restaurant_spec.rb:25:in `block (3 levels) in <top (required)>'

为什么？

Answer 1

使用验证而不是验证。

为什么我的RSpec测试失败了
