使用 Devise 和 RSpec 测试视图 [英] Testing Views that use Devise with RSpec
问题描述
在将 Devise 的 user_signed_in?
方法添加到相关视图模板后,我试图让之前通过的 rspec视图规范"通过.模板看起来像这样:
I am trying to get a previously passing rspec "view spec" to pass after adding Devise's user_signed_in?
method to the view template in question. The template looks something like this:
<% if user_signed_in? %>
Welcome back.
<% else %>
Please sign in.
<% endif %>
传递的视图规范如下所示:
The view spec that was passing looks something like this:
require "spec_helper"
describe "home/index.html.erb" do
it "asks you to sign in if you are not signed in" do
render
rendered.should have_content('Please sign in.')
end
end
添加对user_signed_in?
的调用后产生的错误是:
The error it produces after adding the call to user_signed_in?
is:
1) home/index.html.erb asks you to sign in if you are not signed in
Failure/Error: render
ActionView::Template::Error:
undefined method `authenticate' for nil:NilClass
# ./app/views/home/index.html.erb:1:in `_app_views_home_index_html_erb__1932916999377371771_70268384974540'
# ./spec/views/home/index.html.erb_spec.rb:6:in `block (2 levels) in <top (required)>'
网络上有很多关于此错误的参考资料,但我还没有找到足够描述性的答案,以使我的测试再次通过.我相信这个问题与视图(正在与任何模型/控制器隔离测试)没有一些关键的设计基础设施可用.感谢您的建议.
There are plenty of references to this error around the web, but I have yet to find an answer descriptive enough that I can get my test passing again. I believe the problem has something to do with the view (which is being testing in isolation from any models/controllers) not having some key Devise infrastructure available. Your suggestions are appreciated.
此外,一旦测试通过,我将如何测试其他路径(用户已登录)?我想它会非常相似.谢谢.
Also, once the test passes, how would I test the other path (user already signed in)? I presume it will be very similar. Thanks.
推荐答案
您收到的错误是因为您需要包含设计测试助手
The error you're receiving is because you need to include the devise test helpers
通常您会将此(并且您可能已经拥有)添加到 spec/support/devise.rb
Generally you'll add this (and you might already have) to spec/support/devise.rb
RSpec.configure do |config|
config.include Devise::TestHelpers, :type => :controller
end
但是由于您正在创建视图规范,因此您需要如下内容:
But since you're creating a view spec, you'll want something like this:
RSpec.configure do |config|
config.include Devise::TestHelpers, :type => :controller
config.include Devise::TestHelpers, :type => :view
end
