Not able to use .ts files with Jasmine and Karma. Getting error 'Unable to determine file...

I really need some help to configure karma.conf.js to handle typescript files or not sure what is missing or what I am doing wrong here. Pretty new to unit-testing and learned the Jasmine framework (in the examples it uses *.js and *.spec.js files) but in my ionic-angular project its *.ts files and getting errors (shown below). I have been trying to figure it out for 2 days and not able to get this solved. Any help really appreciated.

[Using ionic 3 (ionic-angular 3.9.+) framework with Angular 6 (6.1.10) and typescript (3.8.+.)]

my tsconfig.json >

my karma.conf.js >

module.exports = function (config) {
config.set({

'karma-jasmine-matchers',
'karma-chrome-launcher'
