ruby-on-rails - rails 2.3.8 : How to functionally test the root route by requesting '/' ?

Question

Rails 2.3.8(使用 Mocha 测试)

在我的 routes.rb 文件中:

map.root(:controller => 'application', :action => 'render_404_not_found')

在我的功能测试中，我想验证对“/”的请求将妥善处理:

@controller.stubs(:render_404_not_found).returns(666)
%w( HEAD GET POST PUT DELETE ).each do |method|
  @request = ActionController::TestRequest.new
  @request.env['REQUEST_URI'] = uri
  @request.path = uri
  process(uri, nil, nil, nil, method)
  assert_response(666,
                  "Request for '#{method} #{uri}'" +
                  'should have 404ed (or 666ed)')
end

我意识到 stub “返回”子句不正确，但我没有到那里了:

test_bogus_uri_path(EdgeConditionsTest):
ActionController::RoutingError: /usr/lib/ruby/gems/1.8/gems/ \
actionpack-2.3.8/lib /action_controller/routing/route_set.rb:420: \
in `generate': No route matches {:controller=>"application", :action=>"/"}

那么我该如何测试这条路线是否有效并调用#render_404_not_found？

谢谢!

基于@noodl 的优秀建议的最终解决方案:

uri = '/'
%w( HEAD GET POST PUT DELETE ).each do |method|
  assert_routing({
                    :method     => method.downcase,
                    :path       => uri
                  },
                  {
                    :controller => 'application',
                    :action     => 'render_404_not_found'
                  },
                  {},
                  {},
                  "'#{method} #{uri}': " +
                  'Root route #failed')
end

#
# Now, ensure that our function is actually getting called..
#
%w( HEAD GET POST PUT DELETE ).each do |method|
  send(method.downcase.to_sym, uri)
  assert_response(404,
                   "Request for '#{method} #{uri}'" +
                   'should have 404ed')
  assert_template('404.html')
end

如果您的目标是测试对 / 映射的请求是否一致，则需要改用集成测试。在 Rails 的功能测试中，各种名为 helper 的 http 方法接受操作名称作为它们的参数，而不是 URI。

Helpers available to functional tests

Code for the above

此外，assert_routing
