rspec 视图存根和部分 [英] rspec view stubs and partials

问题描述

我正在使用 RSpec(Rails 3.2.8 上的 2.12)测试视图.我正在使用 CanCan 有条件地在页面上显示某些元素.这需要一个控制器方法current_user".在我的一些规范中，我已经能够排除 current_user，例如.controller.stub(:current_user).and_return(etc)或者视图.存根.等.

I'm testing a view with RSpec (2.12 on Rails 3.2.8). I'm using CanCan to conditionally display certain elements on a page. This requires a controller method 'current_user'. In some of my specs I've been able to stub out current_user, eg. controller.stub(:current_user).and_return(etc) or view.stub.etc .

这适用于我的一些规格.但我有几个地方无法正常工作，我不明白为什么.

This works for some of my specs. But I've got a couple where it's not working and I don't understand why.

它不工作的两个规范测试了一个视图，它调用了一个局部，在局部内部我访问了current_user"作为一个方法.错误是

The two specs where it's not working test a view, which calls down into a partial, and inside the partial I access 'current_user' as a method. The error is

undefined local variable or method `current_user' 

所以我想我的问题是如何正确地存根方法，以便可以在部分内部访问它们.

So I guess my question is how to stub methods correctly so that they can be accessed down inside partials.

应该怎么做?

推荐答案

控制器存根不起作用，因为您不是在测试控制器，而是在测试视图.只需使用视图存根:

A controller stub won't work because you're not testing a controller, you're testing a view. Just use a view stub instead:

view.stub(:current_user).and_return(etc)

这应该在局部和视图中都有效.

This should work in a partial as well as in a view.
