没有测试的代码就是耍流氓

1. rspec(1) - summary
2. specs(2) - model
3. specs(3) - controller
4. specs(4) - request
5. specs(5) - mock
6. [specs(6) - mailer]
7. [specs(7) - view]
8. [specs(8) - routing]
9. [specs(9) - helper]
10. [specs(10) - factory-girl]
11. [specs(11) - fake other gems]

14. [specs(14) - timecop]
15. [specs(15) - jenkins]

models specs

models的测试默认位于spec/models目录，任何设置:type => :model 当将被当做model specs代码。

创建User模型

rails generate model user name:string sex:integer age:integer

生成model测试(以User为例)

rails generate rspec:model user

迁移

bundle exec rake db:migrate RAILS_ENV=test
# or rails db:mirate RAILS_ENV=test

create测试(spec/models/user_spec.rb)

require "rails_helper"
RSpec.describe User, :type => :model do
    it "create" do
        user = User.create!(:name=>"zouqilin", :sex=>1, :age=>26)
        expect(User.first).to eq(user)
    end
end

find测试

require "rails_helper"
RSpec.describe User, :type => :model do
    before("find") do
          @user = User.create!(:name=>"zouqilin", :sex=>1, :age=>26)
    end
    it "find a user" do
        expect(User.find_by_name("zouqilin")).to eq(@user)
    end

    it "not found" do
          expect(User.find_by_name("zou")).to eq(nil)
    end
end

where测试

require "rails_helper"
RSpec.describe User, :type => :model do
    before("find") do
          @user = User.create!(:name=>"zouqilin", :sex=>1, :age=>26)
    end
    it "find a user" do
        expect(User.where(name: "zouqilin")).to eq([@user])
    end

    it "not found" do
          expect(User.where(name: "zou")).to eq([nil])
    end
end

update测试

  context "update" do
    before("update") do
      @user = User.create!(:name=>"zouqilin", :sex=>1, :age=>26)
    end

    it "update user age" do
      @user.age = 18
      @user.save
      expect(User.find(@user.id).age).to eq(18)
    end
  end

destroy测试

  context "delete" do
    before("delete") do
      @user = User.create!(:name=>"zouqilin", :sex=>1, :age=>26)
    end

    it "delete user" do
      @user.destroy
      expect(User.where(id: @user.id)).to eq([])
    end
  end

关联模型
