Yes, but onboard a Y-20, not yet C919.

Why the Y-20 and not the IL-76 testbed? Or has it already done with the IL-76 and is not being put on a less specialized aircraft for next phase testing?
Or has a specialzed Y-20 replaced the Il-76 as engine testbed?

I don't know where/when the idea of MTU/RR/Avio participating in CJ-1000 program got started, but it's been circulating for a while now and I certainly have never seen any official confirmation or denial of it. So at this point I'm not sure about it either way.
Here is a report that might indirectly be helpful to figure out the answer.
The most relevant part:
Basically, it's an interview with the Engineering General Manager of GE Aircraft Engine China, Mr. Wang Peng. In the section above, he says GEAE has a lot of Chinese suppliers and many aircraft engine components are made in China (for GEAE). He says that export controls on related aircraft engine technologies do exist. But in reality it is more myth than limitation, because very limited amount of parts and components are not allowed to be made in China with the strictest export control on the hot section of the engine, namely high-pressure turbine and combustion chamber. In fact, even some components of HP turbine or combustion chamber are allowed to be made in China. Some are already, such as the plate of HP turbine or the head section of the combustion chamber. They have thought about having other components of HP turbine or combustion chamber to be made in China, which they didn't end up doing not because of export control but because cost issue. Others examples: shaft of high-pressure rotor are made in China, but low-pressure rotor shaft are not because Chinese technology is still not there yet.
The bottom line is that 80-90% of the components are allowed to be made in China and a lot of them are.
My takeaways from the interview is that China can and has built a lot of components for GEAE (and other foreign engine makers). The real gaps are likely in the most sensitive and difficult sections of the aircraft engine, namely high-pressure turbine and combustion chamber. But here China is not exactly starting from scratch. It can certainly leverage its experience and technologies developed for the military aircraft engine. Based on this reasoning, it's possible that CJ-1000/CJ-2000 are entirely being developed by China, although this is not direct, nor even indirect evidence that this is true. We'll still have to get official confirmation one way or another.

That was from 2011. RR has been unusually quiet about that.
Think the idea started all the way back in 2010 or 2012 when the initial project plan for the CJ-1000 was first announced. Then the CJ-1000 disappeared for a while and once it came back in the picture it seemed to have become a different project.
According to the sources, I don't think CJ-1000 has been tested on the flight. What this news said is the new aero-based engine test platform made its maiden flight and the engine mounting test. It's a new platform, so it's essential to test if all the systems and functions are good in the sky. So, why mount a brand-new engine on its maiden flight? After the test platform is confirmed to be perfect, then it will enter service and its first customer will be CJ-1000. What we will see then is "the new aero-based engine test platform finished its first test mission."
