bash regexp "find anything between last slash and dot"

the source string is a path, let's say

/home/test/test/filename.ext

I need to match filename from path and catch it in a BASH_REMATCH

I've tried hundred of figures, it really makes my eyes water, the closest is 

/[^/]*.$

but it only match filename.ext

and \/([a-zA-Z0-9]+)\.

but it match /filename.

Thank you

You should use the end anchor 

([^/]+)\.[^/.]+$

Then filename is in group 1.

You can use:

s='/home/test/test/filename.ext'
[[ "$s" =~ /([^./]+)\. ]] && echo "${BASH_REMATCH[1]}"
filename
