我有一个带有“页面控制器”的Rails4应用程序。
当找不到页面时,show-方法抛出一个自定义的异常'PageNotFoundError‘。
在控制器之上,我定义了rescue_from PageNotFoundError, with: :render_not_found
render not found
是PagesController
的私有方法,如下所示:
def render_not_found
flash[:alert]=t(:page_does_not_exists, title: params[:id])
@pages = Page.all
render :index, status: :not_found #404
end
开发模式下的rails-log显示:
Started GET "/pages/readmef" for 127.0.0.1 at 2013-08-02 23:11:35 +0200
Processing by PagesController#show as HTML
Parameters: {"id"=>"readmef"}
..
Completed 404 Not Found in 14ms (Views: 12.0ms)
因此,到目前为止,它看起来是my :status => :not_found works。
当我做curl -v http://0.0.0.0:3000/pages/readmef
curl日志时
curl -v http://localhost:3000/pages/readmef
* About to connect() to localhost port 3000 (#0)
* Trying 127.0.0.1...
* connected

< HTTP/1.1 404 Not Found
< X-Frame-Options: SAMEORIGIN
但以下使用RSpec的测试失败:
it 'renders an error if page not found' do
visit page_path('not_existing_page_321')
expect(response.status).to eq(404)
within( '.alert-error' ) do
page.should have_content('Page not_existing_page_321 doesn\'t exist')
end
end
1) PagesController renders an error if page not found
Failure/Error: expect(response.status).to eq(404)
expected: 404
got: 200
一切看起来都很好,甚至连test.log都说404
$ tail -f log/test.log
Started GET "/pages/not_existing_page_321" for 127.0.0.1 at 2013-08-03 09:48:13 +0200
Processing by PagesController#show as HTML

Rendered layouts/_locales.haml (0.3ms)
Rendered layouts/_footer.haml (0.6ms)
Completed 404 Not Found in 6ms (Views: 4.5ms)
我试过不同的服务器,WebRICK,Thin,unicorn。在开发和生产模式下,一切都按预期工作。即使test.log也是正确的,但是测试失败了。
谁能告诉我为什么测试结果是200而不是404?

尽管我对这个解决方案不是很满意,但至少这是一个变通的办法:
我将测试分成两个不同的规格。一个用于测试响应代码404 (使用GET而不是访问),另一个用于测试警报。第二个测试是必要的,因为即使render_views
是在规范文件之上定义的,get
也不会呈现视图。
it 'response with 404 if page not found' do
get :show, { controller: 'pages', id: 'not_existing_page_321' }
expect(response.status).to eq(404)
end
it 'renders an error-message if page not found and shows index' do
visit page_path('page_not_found')
within '.alert-error' do
page.should have_content("Page page_not_found doesn't exist")
end
end

RSpec 3+的另一种方法是测试异常:
it 'responds with a 404 if the page is not found' do
expect { get(:show, id: 'bad_id') }.to raise_error(ActionController::RoutingError)
end
