这个rspec助手测试我在做什么错? [英] What am I doing wrong with this rspec helper test?
问题描述
我要做的只是说明视图的单行助手方法应如何表现,但是我不确定如果正在使用哪种模拟对象(如果有)应该创建滑轨.
All I'm trying to do is spec how a one line helper method for a view should behave, but I'm not sure what kind of mock object, (if any) I should be creating if I'm working in Rails.
这是events_helper.rb的代码:
Here's the code for events_helper.rb:
module EventsHelper
def filter_check_button_path
params[:filter].blank? ? '/images/buttons/bt_search_for_events.gif' : '/images/buttons/bt_refine_this_search.gif'
end
end
这是我在specs_helper_spec.rb中的规范代码:
And here's my spec code, in events_helper_spec.rb:
require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')
describe EventsHelper do
#Delete this example and add some real ones or delete this file
it "should be included in the object returned by #helper" do
included_modules = (class << helper; self; end).send :included_modules
included_modules.should include(EventsHelper)
end
it "should return the 'refine image search' button if a search has been run" do
# mock up params hash
params = {}
params[:filter] = true
# create an instance of the class that should include EventsHelper by default, as the first test has verified (I think)
@event = Event.new
# call method to check output
@event.filter_check_button_path.should be('/images/buttons/bt_search_for_events.gif')
end
end
当我在这里浏览文档时- http://rspec.info/rails /writing/views.html ,我对模板"对象的来源感到迷惑.
When I've looked through the docs here - http://rspec.info/rails/writing/views.html, I'm mystified as to where the 'template' object comes from.
我也尝试过看这里,我认为这会指向正确的方向,但是可惜没有骰子. http://jakescruggs.blogspot.com/2007/03/模拟ingingstubbing-partials-and-helper.html
I've also tried looking here, which I thought would point me in the right direction, but alas, no dice. http://jakescruggs.blogspot.com/2007/03/mockingstubbing-partials-and-helper.html
我在做什么错了?
谢谢

推荐答案
在该规范中,您没有做任何事情,只是设置了一个存根,以便它可以通过,但未进行任何测试.
You are not doing anything in that spec, just setting a stub, so it will pass, but hasn't tested anything.
require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')
describe EventsHelper do
it "should return the 'refine image search' button if a search has been run" do
# mock up params hash
params = {:filter => true}
helper.stub!(:params).and_return(params)
helper.filter_check_button_path.should eql('/images/buttons/bt_search_for_events.gif')
end
end
