* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

bad87fee1348bd9aed908626 Identificare lo stesso elemento con diversi selettori jQuery 6 18322

--description--

Ora conosci tre modi per identificare gli elementi: per tipo: $("button"), per classe: $(".btn"), e per id $("#target1").

Anche se è possibile aggiungere più classi in una singola chiamata di .addClass(), aggiungiamole allo stesso elemento in tre modi diversi.

Usando .addClass(), aggiungi una sola classe alla volta allo stesso elemento, in tre modi diversi:

Aggiungi la classe animated a tutti gli elementi di tipo button.

Aggiungi la classe shake a tutti i pulsanti di classe .btn.

Aggiungi la classe btn-primary al pulsante con id #target1.

Nota: Dovresti identificare un elemento e aggiungere una sola classe alla volta. Complessivamente, i tuoi tre selettori individuali finiranno per aggiungere le tre classi shake, animatede btn-primary a #target1.

--hints--

Il tuo codice dovrebbe utilizzare il selettore $("button").

assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?button\s*?(?:'|")/gi));

Il tuo codice dovrebbe utilizzare il selettore $(".btn").

assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?\.btn\s*?(?:'|")/gi));

Il tuo codice dovrebbe utilizzare il selettore $("#target1").

assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?#target1\s*?(?:'|")/gi));

Dovresti aggiungere una sola classe con ognuno dei tre selettori.

assert(
  code.match(/addClass/g) &&
    code.match(/addClass\s*?\(\s*?('|")\s*?[\w-]+\s*?\1\s*?\)/g).length > 2
);

Il tuo elemento #target1 dovrebbe avere le classi animated shake e btn-primary.

assert(
  $('#target1').hasClass('animated') &&
    $('#target1').hasClass('shake') &&
    $('#target1').hasClass('btn-primary')
);

Dovresti usare solo jQuery per aggiungere queste classi all'elemento.

assert(!code.match(/class.*animated/g));
