Angular5 click select in component test

I have tried the following to try to click an option in a select dropdown none of which work.

selectEl = fixture.debugElement.query(By.css('#dropdown'));
selectEl.nativeElement.options[3].nativeElement.dispatchEvent(new Event('click'));
selectEl.queryAll(By.css('option'))[3].nativeElement.click();
selectEl.nativeElement.options[3].nativeElement.click();

After each i run fixture.detectChanges(); to run the change detection but when I go to check the elements value it hasn't changed. expect(selectEl.nativeElement.options[selectEl.nativeElement.selectedIndex].textContent).toBe('name2');

Am I missing something simple to get this to work?
