Testing · Middle · Question 8 of 75

What does `vi.runAllTimers()` do differently from `vi.advanceTimersByTime(1000)`?

✓Correct answer: It runs all pending timers (and timers they schedule) until none are left; advanceTimersByTime moves the clock only by the given amount
2They are the same
3runAllTimers uses the real clock

Explanation

With an endless setInterval, runAllTimers gives up after a limit of iterations - use runOnlyPendingTimers or advance by time.
