While there are tests for the front wings, the rear wing tests are totally inadequate.
The rear wing tests are downward deflection tests, but I doubt that anything is being done about the upward deflection of the DRS flap.
Last year Mclaren took advantage of this with a much talked about mini DRS, FIA dont know what they have done other than reducing the slot gap. While mini DRS was being spoken about the real impact of that flap when the DRS was open was never talked about. The flex upwards of the flap when DRS is open along with the small upward flick of the flap at the leading edges is sureling more than 85mm. How is this being ensured by FIA for fair competition?
It is not only Mclaren which run upward flick in the flap, Ferrari, Red Bull, Mercedes all run that profile
