How to import 'describe', 'expect' and 'it' into a typescript tests for IDE to not to highlight them
<p>Wrote some tests and everything successfully runs, but my IDE (webstorm) highlights <code>describe</code>, <code>expect</code> and <code>it</code> and says "cannot find name". I want to keep everythig clean and get rid of these, but have no idea how.</p>

<p>We use protractor and jasmine.</p>

<p>Some more of the script:</p>

<pre><code>import {HomePO} from './pageobjects/home'
import {browser } from 'protractor'


describe('Smoke test', function() {

    it('should initialize', function() {
        let width = 320;
        let height = 568;
        browser.driver.manage().window().setSize(width, height);
    });

    it('should open homepage', function() {
        HomePO.get();
        expect(HomePO.isCurrentPage()).toBe(true);
    });
});
</code></pre>
