Question

我在测试我的Rails应用程序时遇到了一些问题。

我有简单的以下文件来测试控制器（依赖http://guides.rubyonrails.org/testing.html）：

require "./test/test_helper"
class GraphControllerTest < ActionDispatch::IntegrationTest

    setup do
        @instance = Instance.where(client_id: 2).first
    end

    test "should_create" do
        assert_difference('Graph.count') do
            post v2_instance_graphs_url(instance_id: @instance.client_id), {'name': "test of test", 'instance_id': @instance.client_id}.to_json, {'Authorization': 'Token token=blabla', 'Content-Type': 'application/json'}
        end
        assert_equal JSON.parse(@response.body)["name"], "test of test"
      end
end

使用test_helper.rb：

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  #
  # Note: You'll currently still have to declare fixtures explicitly in integration tests
  # -- they do not yet inherit this setting
  fixtures :all

  # Add more helper methods to be used by all tests here...
end

我在控制台中运行： bin/rake test test/controllers/knowledge_graph_controller_test.rb 这应该只触发上面的两个断言。但是，我得到了两个断言以上和8个错误。

错误如下：

  1) Error:
ActiveSupport::TestCase#test_app=:
ArgumentError: wrong number of arguments (given 0, expected 1)


  2) Error:
ActionController::TestCase#test_app=:
ArgumentError: wrong number of arguments (given 0, expected 1)


  3) Error:
Minitest::Test#test_app=:
ArgumentError: wrong number of arguments (given 0, expected 1)


  4) Error:
GraphControllerTest#test_app=:
ArgumentError: wrong number of arguments (given 0, expected 1)


  5) Error:
ActionDispatch::IntegrationTest#test_app=:
ArgumentError: wrong number of arguments (given 0, expected 1)


  6) Error:
Minitest::Unit::TestCase#test_app=:
ArgumentError: wrong number of arguments (given 0, expected 1)


  7) Error:
Rails::Generators::TestCase#test_app:
RuntimeError: You need to configure your Rails::Generators::TestCase destination root.


  8) Error:
Rails::Generators::TestCase#test_app=:
RuntimeError: You need to configure your Rails::Generators::TestCase destination root.

我无法解释。我甚至不明白他们来自哪个档案。

我使用的是Rails 4.2.7.1

非常感谢你的帮助！

问题是＆＃34;包括ActionDispatch＆＃34;在另一个文件中。

IntegrationTest会从配置中引发错误？
