You can't do that in reality, because if the single engine at one side failed, the aircraft will lose all thrust from that side and can't be balanced, thus the aircraft will be in extreme danger. I think they will use a modified 747 to conduct the test, as it's the biggest quad engine platform they can get.
Also, I don't think they will develop a dual engine Y-20C using two CJ-2000 equivalents, as a quad engine transport plane has more redundancy and could bear a single engine failure (e.g. being hit by an AAM or SAM) when operating near frontlines.

Okay, a couple of things on that.
1) all the modern airliners operate with 2 large engine and are expected to be able to land if one engine fails.
2) this is only for testing. This is not how Y-20 will use in production.

Really? Very impressive if true, but we'll see when it gets here.
I don't know why is this surprising, GEnx will be a 20+ year old product by the time CJ-2000 gets certified. If CJ-2000 can only compete with decade old last gen product then what is the point.

In the aero engine world, getting close to a decade old product like GEnx or LEAP puts you among the very elite because less than a handful of countries can make this equipment. Russia can't. France only through collaboration with GE. It's only the US and UK.

these are well documented CJ-2000 specifications like bypass ratio , CMC blades and 3D printed parts.. back then 3D printed weren't widely use and GEnx didn't have even CMC blades but that doesn't mean engine wasn't good. GEnx is a very reliable machine.

but we have to see how CJ-2000 perform in real environment.

China should be a tier 1 manufacturer not some second line manufacturer in the same ranks as Russia and France. They even said it themselves, that they'd become a top manufacturer by 2030s.

Second tier and above are only four nations besides China. You are already on the leading edge.

With China? Everything in due time. Have they ever disappointed over time?

It is within recent memory that the top engine project most publicized officially in China was the WP-14 turbojet. (And only a handful of countries could build turbojets.) China could pivot decisively, WP-14 was 90% done and then dropped like the steam catapult when China saw better tech.

We are expecting great things on top of rapid advances on top of extraordinary progress. At some point, just savor the process. They just don't disappoint.
