[SOLVED] Pomodoro Clock - test's results different in local and CodePen

Hi everybody,

I hope you can help me, I’m deploying the pomodoro clock in local with “create react app” and when I launch the tester the result is 28/29, but if I paste the code in Codepen the result is 22/29.
It may is a bug of the tester? More probably it’s my code but I can’t figure it out.
Can you take a look and give me some tips?

Update:

This is the only error in local:

  1. The audio element with id of “beep” must stop playing and be rewound to the beginning when the element with the id of “reset” is clicked.

and the result:

Audio element was not rewound when reset was clicked. HINT: use the currentTime property of the audio element to rewind.: expected 0 to equal 3.799665
AssertionError: Audio element was not rewound when reset was clicked. HINT: use the currentTime property of the audio element to rewind.: expected 0 to equal 3.799665

Update 2:

Fixed the last error, the problem was I didn’t use the currentTime properties for audio and video, so now the problem is the difference between the tests.

SOLUTION:

The solution was quite simple, I’ve loaded the wrong external scripts in my Pen settings.
