Question

好吧我说我有以下型号：

class Country < ActiveRecord::Base
  validates_presence_of :name
  validates_presence_of :code
end

我正在为这些验证进行rspec单元测试。它们看起来像这样：

  it "should be invalid without a name" do
    country = Country.new(@valid_attributes.except(:name))
    country.should_not be_valid
    country.errors.on(:name).should == "can't be blank"
    country.name = @valid_attributes[:name]
    country.should be_valid
  end

  it "should be invalid without a code" do
    country = Country.new(@valid_attributes.except(:code))
    country.should_not be_valid
    country.errors.on(:code).should == "can't be blank"
    country.code = @valid_attributes[:code]
    country.should be_valid
  end

这看起来不太干。有没有自动化这种东西的宝石或插件？我希望得到以下几点：

  it "should be invalid without a name" do
    test_presence_validation :name
  end

  it "should be invalid without a code" do
    test_presence_validation :code
  end

值得注意的是：http://github.com/carlosbrando/remarkable

你可以做到

it { should validate_presence_of :name }

Answer 2

如果您使用 factory_girl ，则可以执行以下操作：

  it "should be invalid without a name" do
    FactoryGirl.build(:country, name: nil).should_not be_valid
  end

一个建议......不要在每个规范上使用关键字“should”。相反，写道：“没有名字就无效”

Answer 3

还要尝试accept_values_for gem。它允许做这样的事情：

describe User do

  subject { User.new(@valid_attributes)}

  it { should accept_values_for(:email, "john@example.com", "lambda@gusiev.com") }
  it { should_not accept_values_for(:email, "invalid", nil, "a@b", "john@.com") }
end

rails + rspec：测试验证时保持干燥状态
