Unset all variables set by the script

I use variables in my script and run the script in the following way . ./test.sh. And as it should be, after the script finishes, all the set variables remain in the shell; I know that at the end of the script one can add unset variable variable2. But what if there are a lot of variables, is there a way/command to unset all set variables in the script at once at the end?

Do you need to run it with .? Normally one does that in order to have variable assignments persist afterward.

If you run the script with just ./test.sh then it'll run as a child process with a separate environment from the parent shell. Variable assignments in the child will not affect the parent, and they'll be lost when the child exits.
