在流星中安装摩卡后出错

Question

我想对我的软件做一些测试，所以我在网上找了一些教程，找到了practicemeteor:mocha包。但是在安装包并打开本地之后（无需编写任何测试）。我收到错误提示：

我正在使用流星 1.6.1.1

Answer 1

我将把它作为答案，因为它可能仍然是相关的，所以来到同一点的新用户。

practialmeteor:mocha 是推荐的软件包，但不再与 Meteor >=1.6.1 兼容，并且不再维护它的可能性非常高（您可以在他们的 open gh issues 中看到）。

替代包包括

• cultofcoders:mocha

• meteortesting:mocha

Answer 2

我也遇到过这样的事情，所以我确实花了一些时间才弄清楚。

根据 Meteor Todo App with Angular 教程，推荐使用 practicalmeteor:mocha 包。有趣的是meteortesting:mocha被用在一个典型的scaffold项目中。

  "scripts": {
    "start": "meteor run",
    "test": "meteor test --once --driver-package meteortesting:mocha",
    "test-app": "TEST_WATCH=1 meteor test --full-app --driver-package meteortesting:mocha",
    "visualize": "meteor --production --extra-packages bundle-visualizer"
  },

但是，只有使用从 practicalmeteor:mocha 派生的 cultofcoders:mocha 才有效。

meteor remove practicalmeteor:mocha
meteor add cultofcoders:mocha
meteor test --driver-package cultofcoders:mocha

享受编码！
