测试动作时如何将值放入闪存中 [英] How to put a value in flash when testing an action

问题描述

我正在尝试测试需要将值存储在闪存中的操作.

I'm trying to test an action that needs a value stored in flash.

def my_action
  if flash[:something].nil?
    redirect_to root_path if flash[:something]
    return
  end

  # Do some other stuff
end

在我的测试中，我做了类似的事情:

In my test I do something like:

before(:each) do
  flash[:something] = "bob"
end

it "should do whatever I had commented out above" do
  get :my_action
  # Assert something
end

我遇到的问题是 flash 在 my_action 中没有值.我猜这是因为实际上没有发生任何请求.

The problem I'm running into is that flash has no values inside of my_action. I'm guessing this is because no request actually happens.

有没有办法为这样的测试设置闪光灯?

Is there a way to set flash up for a test like this?

推荐答案

问题在于，按照您的方式使用 flash 散列意味着它只能用于下一个请求.为了将 flash 散列设置为测试值，您可以编写如下内容:

The problem is that using the flash hash the way you do means it only becomes avaialble for the next request. In order to set the flash hash to a value for your test, you could write something like this:

def test_something_keeps_flash
  @request.flash[:something] = 'bar'
  xhr :get, :my_action
  assert_response :success
  // Assert page contents here
end

这可确保您可以检查操作的逻辑.因为它现在会正确设置 flash 哈希，所以输入您的 my_action 并对 flash 哈希执行检查.

This ensures that you can check the logic of your action. Because it will now set the flash hash properly, enter your my_action and perform the check on the flash hash.
