ng test multiple karma configs

If your goal is to have multiple karma configs in your solution to support both your CI pipeline and your local dev enviroment then you can use the –karma-config option in your ng test command to do the same.

You can create a separate karma-local.conf.js (clone of karma.conf.js) in your solution with your custom changes which you want to run on your local enviroment.

You can then run the ng test command like this:

ng test --karma-config karma-local.conf.js

That will run the tests based on karma-local.conf.js settings.
