In brief: Caffeine .

Caffeine stays in your system about 10 -12 hours .
Don't worry though chocolate does not have caffeine in it as far as I know snd it should not affect your stress test results significantly

In brief: Caffeine.

Amount of caffeine in a piece of chocolate cake is low.
Following oral administration of 100 mg of caffeine as a pill (cup of coffee), peak blood concentration reached after 50-75 minutes. Half-life of caffeine is 3-5 hours, so after 6-10 hours, there is no caffeine in the body.
