I simply do not know what the problem seems to be. The error message I get from the test suit isn’t really helpful to me.
Can someone please give me a hint or direction to where I should put my thinking into ?
I somehow figured that setInterval() seems to be pretty inaccurate but the solutions to have a accurate timer are so overkill(at least it seems to me).
The problem is that you decrement running time and only after a second you change the status label. Tests want for it to happen simultaneously. So you should check if new time is “00:00” then you not only update sessionMinutes/seconds, but also timerLabel and isSession.
