I have built a Pomodoro Clock for the beta challenges and everything seems to work fine; however, 6 of the 29 tests are failing all with the same error of: Timeout of 5000 ms exceeded. I can’t work out why these tests are failing even though the clock is functioning perfectly (as far as I can tell).
I had similar problems with this app too. One of them was that the counter has to display time in 4 digits.
Your counter needs to reach 00:00 as it says on the test and not 0:00 like yours does. So when you have less than 10 minutes there needs to be a leading 0 to the minutes.
I know it is pretty picky and it really gave a headache too
