The eval in Testing::DESTROY is called before you print the error. So the script has already forgotten the previous error. You should localize $@ before you run eval blocks.
This should do the fix. 
sub DESTROY {
  my $self = shift;
  local $@;
  eval { $self->{tree} = $self->{tree}->delete(); }; 
}
