Unit testing using Jasmine and TypeScript

Question

I am trying to get a unit test written in Typescript using Jasmine to compile. With the following in my unit-test file, Resharper prompts me with a link to import types from jas

Answer 1

You didn't ask for this, but for bonus points: once you get AJ's answer up and running (using ts-node to invoke the Jasmine startup script), you can add a new task:

"scripts": {
  "watch": "ts-node-dev --respawn -- ./node_modules/jasmine/bin/jasmine src/**.spec.ts"
}

Of course, you can pass your specs or any other arguments using Jasmine's config file instead, if you like. Now, Jasmine will run all your specs once, then ts-node-dev will sit in the background waiting for your tests or anything they might have require'd to change, at which point jasmine will be run again. I haven't worked out a way to only run the tests that have changed (or tests whose imports have changed) yet -- as far as I can tell, that's not supported anyway;
