我遵循了codeschool教程,但我遇到了一些麻烦。
这是 zombie_spec.rb
#spec/model/zombie_spec.rb
require 'spec_helper'
require 'zombie'
describe Zombie do
it 'is invalid without a name' do
zombie = Zombie.new
zombie.should_not be_valid
end
end
zombie.rb
#spec/zombie.rb
class Zombie < ActiveRecord::Base
validates :name, presence: true
...
end
输入rspec spec/models/zombie_spec.rb
后,它会抛出uninitialized constant ActiveRecord (NameError)

Zombie
正在延长ActiveRecord::Base
,但您的代码无法找到ActiveRecord
。
要修复require 'activerecord'
zombie.rb
内的gem install activerecord
。根据是否已安装,您可能还需要从命令行gem 'activerecord'
,或者将Gemfile
添加到bundle install
并运行import android.test.InstrumentationTestCase;
public class exampleTest extends InstrumentationTestCase {
String ob1, ob2;
public void setUp() throws Exception {
super.setUp();
ob1 = "hi";
ob2 = "bye";
}
public void testEx()throws Exception{
assertEquals("Error", ob1, ob2);
}
}

我认为本教程可能试图从在普通Ruby对象上使用RSpec过渡到在ActiveRecord对象上使用rspec-rails
gem。对于使用rspec-rails
的示例,您应该在文件app/models/zombie.rb
中有一个模型。这就是spec/models/zombie_spec.rb
中的规范所要求的内容。此外,您的规范需要rails_helper
而不是spec_helper
。
# app/models/zombie.rb
class Zombie < ActiveRecord::Base
validates :name, presence: true
def hungry?
true
end
end
# spec/models/zombie_spec.rb
require 'rails_helper'
describe Zombie do
it 'is invalid without a name' do
zombie = Zombie.new
zombie.should_not be_valid
end
end

我找到了一个对我有用的例子:
require 'rails_helper'
RSpec.describe Auction, :type => :model do
it "is valid with valid attributes"
it "is not valid without a title"
it "is not valid without a description"
it "is not valid without a start_date"
it "is not valid without a end_date"
end
我是红宝石的新手,所以我不确定100%为什么它需要此“:type”属性,但是它解决了我的问题。
