Javascript Jestjs-未捕获异常：未定义描述\n引用错误：未定义描述

在我的Nodejs应用程序中使用Jestjs进行单元测试时，我发现此错误

uncaughtException:descripe未定义\nReferenceError:descripe未定义。然而，所有的测试在
npm-runtest
中仍然运行良好

我注意到在根文件夹下2层的子文件夹中创建了一个新的测试文件后，出现了错误

我怎样才能修好它

目录树

package.json

eslintrc.json

原来是因为

排除数据库文件夹下index.js中的所有.test.js文件修复了该问题：

const requireDirectory = require('require-directory');

const exclude = (path) => path.includes('test.js');
module.exports = requireDirectory(module, { exclude });

database.test.js
看起来像什么？它只是一个示例测试
description（'database test'，（）=>{It（'Should run the test'，（）=>{expect（true）.toBe（true）；}；}）
