user12146: Where can I find some double spend attempts examples on testnet? Can anyone refer me some TXIDs with double spends on testnet?
EDIT: I need some example in which an outpoint was intended to be used in two different transactions, like this one:
https://blockchain.info/tx/6900440e3bf9d7177ef69b8ca8bb620cb439d9261ce54b3df564f6778547003c
but on the testnet.

user12006: Invalid transactions are not kept as part of the blockchain; they are, after all, invalid. Your best bet might be to listen to the chatter on the network (you'd require a custom-written client for this, I would imagine).
