How do I assert an element is focused?

Question

I am attempting to verify that the focused element is set on page load as one of my tests.

This seems to be working, and I can verify with the element explorer, but

Answer 1

I managed to find a way to compare an element with the focused one without relaying to any attributes:

element(by.css('div.my-class')).equals(browser.driver.switchTo().activeElement())
    .then(equals => expect(equals).toBe(true));
