The more general need that brought this to light is to document sequences of commands that can be copy 'n pasted directly to a terminal session. Amongst these are commands that create small files in a manner that is human readable and still documents every step. Creating temporary files or directing the reader to "use an editor" deviates from the goal of what is essentially a 100% playback possibility. – froage 4 mins ago

If that's all you're trying to do, just use:

sudo -u yy tee ~yy/test.sh >/dev/null <<'EOF'
script-content
EOF

Much simpler and you don't need to fiddle about with the quoting problems of sticking the whole thing inside a bash -c '...' construct. Especially if you have any quotes in your script, this will make it a lot easier.

(Note that the heredoc delimiter definition is quoted as in 'EOF' so that any variables you use in the script-content won't be expanded during the creation of test.sh, which would likely not be your intention.)

Also note the use of tilde expansion to get user yy's home directory: ~yy. See LESS='+/^ *Tilde Expansion' man bash for more on this. That's why you don't need sudo -i.
