问题描述

我最近将我的 Angular 6 应用程序迁移到了 Angular 7

i ve recently migrated my Angular 6 app to Angular 7

运行时奇怪:ng test --watch=false --code-coverage

服务器无限期地继续运行和重新运行测试，没有停止，也没有生成覆盖文件.

The server keeps running and re-running the tests undefinitely , without stopping and without generating the coverage files .

这个问题好像很奇怪

建议??

推荐答案

试试这个命令 ng test -- --watch=false --code-coverage
