Catalina - install on a new Partition or new Volume?

[udflyer]

I went to create a new partition and Disk Utility really tries to lead you to a new volume instead.

Does it matter which I create to test out Catalina?

TIA

If you have APFS, just create a new Container/Volume. It shares free space with its siblings.

I was under the impression that APFS volumes usually share an existing container and therefore are not bootable. Partition on the other hand creates a new container and is bootable. What did I miss?

Apple actually has a support document for using APFS Volumes to install macOS https://support.apple.com/en-us/HT208891 works fine and boots just done it today

They are bootable. There can be hidden size issues. I just added an APFS container to a larger disk and then realized that I needed more space on that new container. I deleted a bunch of files in the other did not free up the space I needed.
Note that the installer will create a second APFS container for the data portion of the install.

So in essence I could have a Macintosh SSD and High Sierra as bootable volumes both under the Container disk1? No need for container disk2?
