是否可以使用angular-cli`ng test`运行angularJS单元测试？

Question

I work on an AngularJS 1.6.X ES6 application. I use Mocha and Sinon to write and run unit tests on it.

I started to hybrid/upgrade this application with ngUpgrade in order to write the new components in angular. So now, I got some angularJS modules and some angular modules. I use @angular-builders/custom-webpack with babel-loader and ng-annotate-loader to properly load the AngularJS modules.

I want to run the existing unit tests of the AngularJS modules at the same time as the unit tests of the new angular modules. Ideally, I would also like to have a common code coverage report for AngularJS and angular modules.

Is it possible to do it with angular-cli ng test ? Which Karma configuration do you recommend?

Yes, I think so. If you are running Angular 6 or higher, but I have not tried this myself.

Angular CLI introduced something called "builders" which allows you to replace the core CLI commands with your own functionality.

Basically, you can define your own ng run <target> targets that work similuar to npm run <script> . These targets are defined in your angular.json file and are coded in a JavaScript file. You can then map the built in target ng test to a custom target to replace the built it one.

The above article gives an example for replacing ng test with a custom tester.
