rspec 路由测试和主机

RSpec是一个流行的Ruby语言测试框架，它被广泛用于测试Rails应用程序中的路由。在Rails中，路由是定义应用程序如何响应特定请求的重要组成部分。通过编写路由测试，您可以确保请求被正确路由到预期的控制器和动作上。此外，您可以使用RSpec的主机功能来模拟特定的请求主机，以确保应用程序在不同环境中都能正确工作。

ruby
Rails.application.routes.draw do
  get 'welcome/index'
  resources :articles
end

ruby
RSpec.describe "Routing", type: :routing do
  it "routes GET /welcome/index to the welcome controller's index action" do
    expect(get: "/welcome/index").to route_to("welcome#index")
  end
  it "routes GET /articles to the articles controller's index action" do
    expect(get: "/articles").to route_to("articles#index")
  end
  it "routes GET /articles/1 to the articles controller's show action" do
    expect(get: "/articles/1").to route_to("articles#show", id: "1")
  end
  it "routes POST /articles to the articles controller's create action" do
    expect(post: "/articles").to route_to("articles#create")
  end

ruby
RSpec.describe "Routing", type: :routing do
  it "routes GET /articles to the articles controller's index action from a specific host" do
    expect(get: "http://example.com/articles").to route_to("articles#index")
  end
