"How was it done?" or "How could it happen?" How was it done has many answers that are technically easy. I don't know the specifics about VW's software but if the lab test is performed on a drive wheel rollers then it is easy for the ABS software to detect that the drive wheels are turning, but the others wheels are not. Then the ABS code could tell the emissions code to run with clean parameters instead of best power/economy parameters. The ways to accomplish the cheat are limited only by imagination, but they are still cheats. The flexibility of computers, software and sensors makes the technical part easy. The bigger question is how could a company could cheat against the environment and its customers. I hope VW makes this right and the episode is a wake up call for the industry.
