I'm building a project with bitcoins and want to test it with testnet. However, I don't have any testnet bitcoins, and despite the difficulty being less than 100 usually, I still haven't been able to mine a block on my PC (CPU only) after a day. Is there anywhere I could get just some small amount of testnet bitcoins for testing?
Looks like you can get some here: http://tpfaucet.appspot.com/
The term "faucet" has been used for quite some time for a site giving away small quantities of coins for free. If the above link ever stops working, a web search for "bitcoin testnet faucet" may find a different site.
One more site to get free test bitcoins...
