I'm expecting this script to write the output from my test.pl script to output.log and errors from the test script to error.log, however both files are created, but empty.

Unfortunately, you can't just link one thing to another using a single filehandle. You'll have to create some data pipe yourself: read out the programs stdout and stderr, and write it back to the files you want. Don't forget to waitpid, after which $? will have the status code.
