流星导入目录测试文件不急于加载

Meteor version 1.7.0.5
Using meteortesting:mocha

我有一个非常简单的流星反应应用程序。我在中添加了一个测试文件 imports/startup/simple-schema.tests.js

describe('Todos_item', function () {
  console.log('Todo');
});

npm run test-app tests/main.js Todo 已登录控制台。所以我错过了什么。

包.json

  "name": "meteor-bootstrap",
  "private": true,
  "scripts": {
    "start": "meteor run",
    "test": "meteor test --once --driver-package meteortesting:mocha",

  },
  "engines": {

}

任何帮助都将不胜感激。提前谢谢。
