javascript - jasmine 2 - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL

Question

Having trouble with jasmine 2 and getting async specs wired up:

define(['foo'], function(foo) {
  return describe('foo', function() {
    beforeEach(function(done) {
      window.jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;
      return setTimeout((function() {
        console.log('inside timeout');
        return done();
      }), window.jasmine.DEFAULT_TIMEOUT_INTERVAL);
    });
    return it('passes', function() {
      return expect({}).toBeDefined();
    });
  });
});

When I run via karma, I get back

Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL.

and then the specs fail. I have attempted to override the default timeout but I can't get past the error

You are using the same timeout interval as Jasmine is using to fail tests on timeout, i.e. your timeout is triggered to fire with Jasmine's default interval, which fails the test.

If you set your timeout to be less than jasmine default timeout the test passes.

describe('foo', function () {
    beforeEach(function (done) {
        window.jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;
        setTimeout(function () {
            console.log('inside timeout');
            done();
        }, 500);
    });
    it('passes', function () {
        expect({}).toBeDefined();
    });
});
