Narrative:

Approaching white sands testing area; ATC warned us that 'radar jamming' was being tested/used. While at cruise; we were 'jammed' numerous times. Warnings that would be expected with this process occurred numerous times. The nav accuracy was downgraded and upgraded to normal the first few times that we were jammed. Then; ECAM notified of GPS 1 failure and then went away. A few minutes later ECAM notified of GPS 2 failure and then went away. We incorrectly concluded that the GPS systems had reset themselves; but the navigation accuracy downgrade notice never went away (on the nd). After checking GPS condition on the FMC; it became clear that we had no GPS positions left. We advised ATC that we needed a non-RNAV arrival. They provided vectors to a visual approach.stop jamming commercial air traffic.

Title: A319 pilot reported that while approaching White Sands Testing Area in New Mexico; ATC warned of 'radar jamming' which affected GPS. Following several GPS 1 and GPS 2 ECAM alerts; all GPS position reporting was lost for the remainder of the flight.

Then; ECAM notified of GPS 1 failure and then went away. A few minutes later ECAM notified of GPS 2 failure and then went away. We incorrectly concluded that the GPS systems had reset themselves; but the NAV ACCURACY DOWNGRADE notice never went away (on the ND). After checking GPS condition on the FMC; it became clear that we had no GPS positions left. We advised ATC that we needed a non-RNAV arrival.
