I have a wrapper class for memcache-client (adds a little extra  
functionality for something specific I need). Does anyone have any good  
ideas for how to do unit testing on it?

The issue I have is that the memcache will become full of data from each  
functional test I run. It would be nice to have a “clean slate” each  
time I run. To me, the obvious thing would be to start and stop a  
memcached server for each of my tests, but that seems like a major pain.  
Is there something I’m missing like a clear\_memcache function or  
something?

Thanks!

Use mocks. Check the cache\_fu tests, which run against mocks and a  
real memcached server.

Look at how the memcache-client tests are written. They never touch  
a server.
