我正在使用"带有Rails 4"的书"敏捷Web开发"，并且正在通过第7章，这与测试有关。该教程包括一个产品模型，并让读取器修改测试文件product_test.rb，显然应该在test/models.中的测试指南中也具有此结构。但是由于某种原因，我的测试目录中没有模型子目录。我的测试目录看起来像这样：
[~/code/depot]: ls test
fixtures functional integration performance test_helper.rb unit
我的product_test.rb文件在"单元"文件夹中。
当我尝试运行书中所示的测试时，这会导致问题。rake test和ruby -Itest test/unit/product_test.rb一样工作正常，但是rake test:models产生以下错误：
[~/code/depot]: rake test:models
rake aborted!
Don't know how to build task 'test:models'
(See full trace by running task with --trace)
我不太了解耙子命令，但是我假设当我运行rake test:models时它正在寻找test/models吗？无论如何，它不起作用，我不知道为什么我的测试目录结构缺少模型文件夹以及为什么我的product_test.rb代替test/unit。测试导轨指南还表明脚手架生成的模型应在test/models中进行测试。谁能解释可能发生的事情或我应该如何解决此问题？
