I have written unit tests using jasmine framework for angular 2 typescript application. I have not generated project using angular-cli. I installed jasmine and wrote the unit testing for angular component. How do I run this spec.ts ? I followed this https://github.com/jasmine/jasmine-npm and try to configure my project to run the tests. But this works only for spec.js test files. I tried with karma and did not work. How to setup the test environment to run tests written for typescript using jasmine?

To get your typescript files compiled into javascript, use tsc compiler. Install it by running
$ npm i typescript
$ npm i typescript -g
And initialize tsconfig.json:
$ tsc --init
Now you can compile your files by simply running tsc in the project directory.
jasmine-npm specifies that you should run your tests by executing jasmine. So you can add the following to the package.json:
"scripts": {
"test": "tsc && jasmine"
},
and execute tests by simply running:
$ npm test

I tried but I get this error after compiling typescript to javascript
import { TestBed } from '@angular/core/testing'; SyntaxError: Unexpected token import

I ran into the same issue, to solve it ensure that in the tsconfig.json "module": "commonjs"
