Understood... I will only CPU mine on testnet.  To do this, all I need to do is edit my local bit coin.conf to `gen=1` for coins?

@makerofthings7: I think so. I haven't used testnet myself, or seriously tried to CPU mine.

@KinnardHockenhull I have `gen=1` on a fast Macbook Retina running for the past 48 hours... nothing.  8 CPUs.  I may have to use my FPGA or weak Nvida card.  Any recommendations? on software?

Unfortunately, this answer is no longer true.  The testnet difficulty is currently around 4 million, and a typical CPU would take many months to mine a block.

If testnet coins are this difficult to get, what's the chance people start throwing in some real money to speed along the process?

@KinnardHockenhull From what I've read, testnet coins are easy to come by, and people have extras and historically just freely traded them.  I don't think they are difficult to get per-se, I just don't know how to get started.

Are there any pools running on testnet?

Testnet is designed to test Bitcoin software - including parts that have to do with finding blocks. As such, it should be easy for developers to generate testnet coins.

Because of this, it will be easy to solo mine on a CPU to generate them, and you should *not* use anything heavier than that because you would ruin it for everyone else.

It is also not designed to test pools, by the way. If you need a pool for whatever you're doing you can do that (but don't bring too much hashpower to it), but if it's the pool itself you're testing, do it on the main net.
