Javascript 吞咽单独工作但不在观察模式下的任务

我正在开发一个运行在node.js上的CLI工具。我正在尝试为tdd设置环境，但我很难用gulp来完成

我所有的“独立”任务都是从gulp工作中完成的。 这是：

生成任务：

测试任务：

如您所见，我有一个任务，将我的typescript文件构建到与es5兼容的js中。还有另一个任务，它使用先例构建运行我的测试

如果我一个人管理他们。它起作用了

我已尝试添加手表模式：

构建：观看：

测试：手表：

建造：手表工作。每次编辑typescript文件时，都会触发生成任务并重新生成项目。这在这里并不重要，因为测试任务触发构建。这只是说，这种手表模式的工作

测试：手表坏了。第一次迭代由任务依赖项触发，但在编辑typescript文件或测试文件时，出现以下错误：

   { domain: null,
     _events: { error: [Function: handleException] },

你有什么建议吗？

好的，我发现了问题所在

我在单元测试中使用mockry，但在一些测试之后忘记禁用它。我只需添加我的测试文件：

 afterEach(function() {
    mockery.disable();
 });

祝你今天愉快。 托马斯
