ruby-on-rails - 将命名路由传递给 RSpec 中的 Controller 宏

Question

我正在尝试通过为常用测试添加一些 Controller 宏来完善我的 RSpec 示例。在这个稍微简化的示例中，我创建了一个宏，它只是测试获取页面是否会导致直接到另一个页面:

def it_should_redirect(method, path)
  it "#{method} should redirect to #{path}" do
    get method
    response.should redirect_to(path)
  end
end

我试图这样称呼它:

context "new user" do
  it_should_redirect 'cancel', account_path
end

当我运行测试时，我收到一条错误消息，指出它无法识别 account_path:

undefined local variable or method `account_path' for ... (NameError)

我尝试按照 this SO thread on named routes in RSpec 中给出的指导包含 Rails.application.routes.url_helpers但仍然收到相同的错误。

如何将命名路由作为参数传递给 Controller ​​宏？

包含在 config.include Rails.application.routes.url_helpers 中的 url 助手仅在示例中有效(使用 it 或 specify 设置的块)。在示例组(上下文或描述)中，您不能使用它。尝试使用符号和 send相反，像

# macro should be defined as class method, use def self.method instead of def method
def self.it_should_redirect(method, path)
  it "#{method} should redirect to #{path}" do
    get method
    response.should redirect_to(send(path))
  end
end

context "new user" do
  it_should_redirect 'cancel', :account_path
end

不要忘记在配置中包含 url_helpers。

或者在例子中调用宏:

def should_redirect(method, path)
  get method
  response.should redirect_to(path)
end

it { should_redirect 'cancel', account_path }
