Or your premises are wrong. Before calling it not real let's allow the testing to continue to see wether our understanding of physics is not enough to explain how it's working, or if there's something that has escaped every study and reproduction of the system. It's certainly not going to take too long before someone puts an EM drive to space to see if it works there too, it's not that expensive to do so when put into context.
