How to run tests written using jasmine for typescript (angular 2)?

Question

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?

Answer 1

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
