【问题描述】：

当我使用 rake test:helpers 为助手运行测试时出现奇怪的错误

ApplicationHelper::dummy#test_0001_必须返回字符串： NameError: Unable to resolve controller for ApplicationHelper::dummy

测试：

require "test_helper"

describe ApplicationHelper do
  include ApplicationHelper
  context "dummy" do
    it "must return string" do
      result = dummy()
      result.must_be_kind_of ( String )
      result.wont_be_empty
    end
  end
end

我的助手

module ApplicationHelper
  def dummy
    "hello world".html_safe
  end
end

我的测试助手

ENV["RAILS_ENV"] = "test"
require File.expand_path("../../config/environment", __FILE__)
require "rails/test_help"
require "minitest/rails"
require "minitest/rails/capybara"
require 'minitest/rg'
require "warden_mock"

class ActiveSupport::TestCase
  fixtures :all
  class << self
    alias :context :describe
  end
end

class ActionController::TestCase
  def setup
    request.env['warden'] = WardenMock.new # mockup warden
    User.current = request.env['warden'].user
  end
  register_spec_type(/.*/, self)
end

导轨 4.1.6 minitest-rails 2.1.0

【问题讨论】：

你为什么要这样做：register_spec_type(/.*/, self) 这使得每个测试都使用 ActionController::TestCase。你不想要那个。尝试删除它。
谢谢！这就是解决方案。我是笨蛋:(

【解决方案1】：

尝试在您的test_helper.rb 中注释掉require "minitest/rails/capybara"，并且仅在您的功能测试中需要它
