I would use local for that:

{
    local $tempdir = '/tmp/foo';
    test_someting();
}

Most likely you need to wrap all these test_something(...) function calls anyway with your code, and that's a good place to set up the localized test fixtures as well.

I'm wondering a bit how you plan to handle one such function calling another function. Should the fixtures be recreated or not?

sub test_someting2( $tempdir, $aValue ) {
    if( $^O !~ /mswin/i ) {
        test_someting("$tempdir/$aValue");
    } else {
        test_someting("$tempdir\\$aValue");
    };
}
