ruby-on-rails - 在 Rails Controller 测试中访问 "request"变量

Question

我有以下代码

require 'test_helper'

class ApplicationControllerTest < ActionController::TestCase
  test "should display the page in german" do
    get :index
    assert_response :success
    # ...
    request.env["HTTP_REFERER"] = :index
    # ...
  end
end

如果我运行这个 Rails 功能测试

$ rake test:functionals

我收到这个错误:

test_should_display_the_page_in_german(ApplicationControllerTest):
NameError: undefined local variable or method `request' for #<ApplicationControllerTest:0x1044c6d00>

如何访问“请求”变量？

Answer 1

@request.env["HTTP_REFERER"] = :index

Testing Guide

4.4 实例变量可用您还可以在功能测试中访问三个实例变量:

@controller – The controller processing the request
@request – The request
@response – The response
