Angular - Unit Testing | Code Coverage | Chrome headless

1) Configuarion in karma.conf.js -

browsers: ['ChromeHeadless', 'Chrome'],

2) Configuarion in package.json

Add a command to execute the test case in headless mode

"test": "ng test",
"test:headless": "ng test --browsers=ChromeHeadless --no-watch"

3) If you want to code coverage as well with headless mode.

--code-coverage=true

So the command will be

"test": "ng test",
"test:headless": "ng test --code-coverage=true --browsers=ChromeHeadless --no-watch"
