【问题描述】：

对于 Strapi 单元测试（使用 mysql 作为数据库），我遵循了官方文档，当我使用 npm run test 运行相同的测试时，我收到如下错误

my-project@0.1.0 测试 D:\Gerrit\website_backend\TE_MCA_DMSWEBV2 开玩笑 --forceExit --detectOpenHandles

● process.exit 以“1”调用

  at Strapi.stop (node_modules/strapi/lib/Strapi.js:238:13)
  at Strapi.stopWithError (node_modules/strapi/lib/Strapi.js:224:17)
  at node_modules/strapi-connector-bookshelf/lib/mount-models.js:625:14

运行测试/app.test.js npm 错误！代码生命周期 npm 错误！错误号 1 npm 错误！我的项目@0.1.0 测试：jest --forceExit --detectOpenHandles npm 错误！退出状态 1 npm 错误！ npm 错误！在 my-project@0.1.0 测试脚本中失败。 npm 错误！这可能不是 npm 的问题。上面可能还有额外的日志输出。

【解决方案1】：

它来自文件夹名称，在文档中它是 ./config/env/test/database.json，但在您的文章中是 ./config/environments /test/database.json.

其实这取决于你的strapi版本，新版本中env。
