伊斯坦布尔没有生成 mocha chai 和 chai-http 测试的覆盖范围
Istanbul is not generating the coverage for mocha chai and chai-http test
我正在尝试为我的 api.I 生成 istanbul 代码覆盖范围，已经研究了 SO 中的许多答案以及 istanbul 的文档，但对我来说没有任何效果。 mocha 测试 运行 很好，一切都通过了，甚至伊斯坦布尔也在创建 coverage 文件夹，但它没有在 it.My 中创建报告应用程序很简单express 应用程序，我正在为此使用 chai、chai-http 和 mocha。下面是我的 test/app.js 文件和 package.json 文件的代码。
