China did test it on the J-10B one engine fighter:
The secret-sauce in the J-10B at Zhuhai was its powerplant: instead of the usual Russian AL-31F(N) turbofan, it boasted a WS-10B Taihang engine normally reserved for use on the larger twin-engine
Chengdu J-20 Mighty Dragon stealth fighter.
More importantly, this particular Taihang (labeled the WS-10G in some sources) was modified with three-dimensional Thrust Vector Controls (TVC) allowing the pilot to redirect the engine’s thrust by tilting the exhaust nozzles side by side as well as up and down.
This enhances the jet’s ability to adjust pitch, roll and yaw, granting the J-10B super-maneuverable flight characteristics, in which the pilot retains control of the aircraft during a stall, unlike for a conventional plane.
