How to unit test model interfaces in typescript?

export interface User {
    name: string;
}

How can I unit test the above interface, so Karma could show it in the code coverage report?

I already tried creating the object and assert some properties, but didn't work. The test passes but karma doesn't consider it in the code coverage report.

import { User } from "./user";

describe('User', () => {

    it('test', () => {
        const obj: User = {
            name: "xxx",

        }
        expect(obj.name).toEqual("xxx");
    });

});
Solution

  • You can't. There is no code to cover here: nothing is executable.

    And interfaces only exist at compile-time. They don't exist at runtime.
