如何测试范围? [英] How to test scopes?
问题描述
试图找到但没有成功.只是想知道如何在 Rails 3 中测试作用域.
tried to find but with no success. Just wondering how could I test scopes in Rails 3.
可能使用 rspec、should 或只是一个测试单元.
Could be using rspec, shoulda or just a test unit.
谢谢.
其实我是这样试的,但是还不是完整的测试,因为还需要放order()方法.
Actually, I trying this way, but it's not complete test since it's still need to put the order() method.
范围:
scope :recents_available, where(:available => true, :locked => false).order("created_at DESC")
describe Job, ":recents_available" do
it "should have the scope" do
Job.should respond_to(:recents_available)
end
it "should include recents jobs that are available and unlocked" do
@job = Factory(:job, :available => true, :locked => false )
Job.recents_available.should include(@job)
end
结束
推荐答案
David Chelimsky(Rspec 的创建者)在 中提供了以下示例Rspec Google 群组:
David Chelimsky (Rspec's creator) offered up the following example in the Rspec Google Group:
describe User, ".admins" do
it "includes users with admin flag" do
admin = User.create! :admin => true
User.admin.should include(admin)
end
it "excludes users without admin flag" do
non_admin = User.create! :admin => false
User.admin.should_not include(non_admin)
end
end
class User < ActiveRecord::Base
named_scope :admins, :conditions => {:admin => true}
end
这显然与您的示例不同,但它应该让您知道如何去做.上下文的相关线程在这里:http://groups.google.com/group/rspec/browse_thread/线程/6706c3f2cceef97f
It's obviously not the same example as yours, but it should give you an idea of how to do it. The relevant thread for context is here: http://groups.google.com/group/rspec/browse_thread/thread/6706c3f2cceef97f
