 Hi @hideokamoto,

 Thanks for updating the patch. I see what's happening. It looks like the
 reason checking the length is not working is due to the selector using the
 `page.$` function, which is the equivalent of `document.querySelector` and
 only returns the first element it encounters.

 If you use `page.$$` (`document.querySelectorAll`) instead the test seems
 to work well:


 {{{
 it( 'Should show admin bar when user logged in' , async () => {
         await loginUser();
         await page.goto( createURL( '/' ) );
         const nodes = await page.$$( '#wpadminbar' );
         expect( nodes.length ).toBe( 1 );
 } );
 }}}
