Angular 2 testing nativeElement

I have been going through the testing tutorial on the angular website. I am curious if there is a listing of all of the items that are available for test through the debugElement. For example

let nav = fixture.debugElement.query(By.css('h1')).nativeElement;

    expect(nav.innerText).toBe(fixture.componentInstance.homeHeader);

What other elements are there like the innerText value that I am testing. Thank you for any help.
