A nice image and nothing more.

Looks like one of the J-20A prototypes, judging by the enlarged hump behind the cockpit.

Machine gun testing? Does that mean the J-20s will be fitted with a cannon in the future?

The fact that tests have been accomplished is well known since years I think and I think common accepted understanding is that most likely no. 2022 once was fitted with a gun.

much excited, about internal gun.

Supposedly the performance of the new 6-barrelled 23mm gun

Due to practicality reasons none of the stealth fighter aircraft can operate above Mach 2.0 in operational setting for very long. You have to consider things like RAM paint, weaponsbay doors, etc. the F-22 is technically capable of M2.35 above speeds but is limited to 2.0 in real world conditions.

Another factor to take into consideration is the DSI, which doesn't work well beyond mach 2, so the engine would run into boundary layer ingestion problems beyond mach 2. I think if the PLA wanted the J-20 to fly at mach 2+, they would have opted for an intake ramp.

DSI speed limit is a myth. It’s a dumb shorthand just like canards can’t be stealthy.
