Sequential decision making studies how a device makes as fast as possible decisions based on the sequential observation of a stochastic process. Here, a statistical test for the optimality of black box decision devices and a related measure for the divergence to optimality of black box decision devices are presented; a device is optimal if the average decision time -- over different realisations of the observed process -- is minimal given a certain maximal allowed error probability. A relation between the presented statistical test and the recently derived fluctuation theorems for first-passage times of entropy production is discussed [1]. Numerical experiments illustrate the use of the test for practical purposes.
