angular-cli - Use multiple karma.conf.js

Question

I am using angular-cli and I want to use two karma.conf.js files for testing.

1. For CI : For which I am using Headless Chrome

   customLaunchers: {

     ChromeHeadless: {
       base: 'Chrome',
       flags: [
         '--headless',
         '--disable-gpu',
         // Without a remote debugging port, Google Chrome exits immediately.
         '--remote-debugging-port=9222',
       ],
     }
   }
   

2. For Dev : For which I am using Chrome.

Is there any way that I could switch betwwen two karma.conf.js based on an argument value.

Answer 1

You can use option karmaConfig:

ng test --karmaConfig=another-karma.config.json

You may want to check ng test --help=true for other options.
