Question

使用RSpec，我如何测试url_for辅助方法以确保它使用特定格式转到正确的控制器和操作？

Answer 1

我必须做以下事情 -

将此添加到spec_helper.rb：

Rspec.configure do |config|
  config.include Rails.application.routes.url_helpers  # url_for
end

然后：

describe "Article routing" do
  it "routes to #index.atom" do
    get('/articles.atom').
      should route_to('articles#index', format: 'atom')

    url_for(:controller => 'articles', :format => :atom, :only_path => true).
      should == '/articles/index.atom'
  end
end

Answer 2

您可以测试命名路由是否路由到正确的位置。路由规范位于spec/routing，因此以下规范将添加到spec/routing/widget_routes_spec.rb

describe "routes to the widgets controller" do
  it "routes a named route" do
    expect(:get => new_widget_path).
      to route_to(:controller => "widgets", :action => "new")
  end
end

有许多其他选项可用于测试routing specs documentation中描述的路线。
