I need to write a test for a function that has a setTimeout() call inside, but i can\'t find how i should do.

This is the function

// Di         


        

Answer 1

Since Jasmine 2 the syntax has changed: http://jasmine.github.io/2.0/introduction.html#section-Asynchronous_Support

You now can simply pass a done callback to beforeEach, it, and afterEach:

it('tests something async', function(done) {
    setTimeout(function() {
        expect(somethingSlow).toBe(true);
        done();
    }, 400);
});

Update: Since writing this it's now also possible to use async/await which would be my preferred approach.
