How to implement unit tests in NativeScript using TestBed and Jasmine?

To use TestBed you have to alter your karma.conf.js to:

    // list of files / patterns to load in the browser
    files: [
      'src/tests/setup.ts',
      'src/tests/**/*.spec.ts'
    ],

The file src/tests/setup.ts should look like this for jasmine:

import "nativescript-angular/zone-js/testing.jasmine";
import {nsTestBedInit} from "nativescript-angular/testing";
nsTestBedInit();

or if using mocha:

import "nativescript-angular/zone-js/testing.mocha";
import {nsTestBedInit} from "nativescript-angular/testing";
nsTestBedInit();

You'll find a sample here: https://github.com/hypery2k/tns_testbed_sample
