ruby-on-rails - Rspec:如何测试 Rails 的 url_for 助手？

Question

使用 RSpec，我如何测试 url_for 辅助方法以确保它以特定格式转到正确的 Controller 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
