Things not looking good for the EMDrive.
While a flippant article, it has some good info,
NASA’s EM-drive is a magnetic WTF-thruster | Ars Technica
Basically the latest tests have shown thrust in the same direction even when they flipped the drive around, leading to the belief measurements of thrust are related to the orientation to the earths magnetic field and aren't being produced by the drive at all. I should ad that the rig they did this in was pretty complex, not only did it have gimbals to move the drive while under vacuum, they then physically flipped the drive on the platform and did all the tests again.
