推荐答案

您需要一个额外的库来覆盖代码，而

You need an additional library for code coverage, and you are going to be blown away by how powerful and easy istanbul is. Try the following, after you get your mocha tests to pass:

npm install nyc

现在，只需将命令nyc放在现有测试命令的前面即可，例如:

Now, simply place the command nyc in front of your existing test command, for example:

{
  "scripts": {
    "test": "nyc mocha"
  }
}
