使用--watch = false的Angular CLI 6覆盖返回错误

Question

When I run

ng test --watch=false --code-coverage --no-progress

I get

Schema validation failed with the following errors:
  Data path ".watch" should be boolean.

I searched but can't find a hit for this error.

The docs ( https://github.com/angular/angular-cli/wiki/test ) clearly say --watch=false should work.

Other people say it works, for example https://github.com/angular/angular-cli/issues/10711#issuecomment-387704999

I'm on angular/cli 6.2.4. angular 6.1.9

Has anyone encountered this?

Answer 1

Do you have more than one project in your angular workspace (angular.json)? I have received this error when running ng test --watch=false on a workspace with multiple projects.

You can run the test command on the project by name eg

ng run PROJECT_NAME:test --watch=false --code-coverage --no-progress

you need to substitute in the name of your project for PROJECT_NAME

Answer 2

尝试singleRun: true,在karma.conf.js配置中，如果您希望测试继续观察更改并自动运行测试。
