angular - Find if element contains element with id -


how can find if element contains element specified id?

<div class="menu">   <div id="signin">sign in</div> </div>

i'm checking query length here thought there might better way:

it('main menu has signin link if not signed in', () => {     fixture.detectchanges();     let links = menuelemdebug.queryall(by.css('#signin-button'));     expect(links.length).tobe(1); })

try simple css selection like:

let links = menuelemdebug.queryall(by.css('.menu> #signin'));

but if going after element id, guess uniquely identified.
