Testable Logger

I like the idea of having unit tests make sure what gets logged.

I found a plugin called "testable logger" at

  http://code.teytek.com/rails/plugins/testable_logger/

This promises to do what I'm looking for.

But the code itself is not available through the links provided. The
author hasn't responded to my email.

Does anyone know an alternative or has a copy of the code to pass on (if
allowed)

Thanks,

Stephan
