Tests like these are often limited to Snapshots which in turn are always limited to only Java players, so the fact that this is available to those on the Bedrock version too means that it’s something that should be taken advantage of if you’re looking to see what’s coming next. The second half of the Caves & Cliffs update includes content which was delayed whenever Mojang decided to split the larger release into two parts.

What you’ll see in these experimental World Generations differs depending on whether you’re on the Bedrock or Java versions of the game. Details pertaining to what’s been added to both versions can be found below with info on how to try out the Java test and the Bedrock test found through the corresponding links.
Java Version: Changes Compared to Caves & Cliffs: Part I
New world height and depth
New mountain biomes (lofty peaks, snowcapped peaks, grove, meadow, and snowy slopes)
New cave generation (cheese, spaghetti, and noodle caves)
Local water levels and lava levels in the underground
New cave biomes generate naturally underground and inside mountains (lush caves, dripstone caves)
Natural variation in terrain shape and elevation, independently from biomes. For example, forests and deserts could form up on a hill without needing a special biome just for that.
New ore distribution (see this chart)
Large ore veins
Integrated mountains, caves, and cave entrances
Monsters will only spawn in complete darkness
Bedrock Version: New Features
New surface biomes including Lofty Peaks, Snow Capped Peaks, Snowy Slopes, Mountain Grove, and Mountain Meadow
New cave biomes including Lush Caves, and Dripstone Caves
Revamped cave generation adds cheese caves, spaghetti caves, lava aquifers, and flooded aquifer caves
New ore distribution
Minecraft’s Caves & Cliffs: Part II update does not yet have a release date but is expected to release at some point this year.
