rspec：测试带约束的路由

Question

I'm using rspec, and currently have a task to test routing. In routes I have:

get ':url' => 'article#get', constraints: lambda { |request|
  Article.public.where(url: request.params["url"]).first
}

get ':url' => 'product#get', constraints: lambda { |request|
  Product.get_publick_prod_by_url(request.params["url"])
}

and test:

let!(:article) {Article.create(name: "qweqwe", 
                            short_description: "sh", 
                            description: "dscr", 
                            public: true, 
                            meta_title: "title", 
                            meta_description: "meta-descr", 
                            meta_keywords: "qwe", 
                            url: "qweqwe")}

before(:each) do
  Epk::Application.reload_routes!
end

it "should route to article" do
  expect(get: article.url).to route_to(controller: 'article', action: 'get', url: "qweqwe")
end

test is not passing for some strange reasons. Output - No route matches "/qweqwe" .

While testing by hands, all code works perfectly, but I want to set up test for it..

Answer 1

The problem is in route_to method, that not passing params for some reasons. In my situation with simple url like "site.com/:url" I can rewrite route's constraints in this way: Article.find_published_by_url(request.path_info.split('/')[1]) , and it works perfectly.
