【问题描述】：

我无法在我的 Angular 项目中运行 mocha 测试，也无法调试这是什么原因。在 .json 包中，我更改了“test”：“mocha -r ts-node/register src/**/test.ts”

npm test

> reusable-components@0.0.0 test /Users/daro/code/reusable-components
> mocha -r ts-node/register src/**/test.ts

/Users/daro/code/reusable-components/src/test.ts:2
import 'zone.js/dist/zone-testing';
^^^^^^

【解决方案1】：

看起来您错过了dot (.) 符号，以运行文件名为*.test.ts 而不是test.ts 的文件。

所以你的测试命令应该是：

"test": "mocha -r ts-node/register tests/**/*.test.ts"
