does testnet coins take long time to confirm ?
You can see the block situation here -
https://tbtc.bitaps.com/blocksThe last block found was 1 hour 20 minutes ago but it's pretty similar to Bitcoin's block generation times usually.
actually it is the only thing that is different between bitcoin testnet and bitcoin mainnet. the difference is in difficulty, it is set in a way that it can drop to 1 if there hasn't been any blocks found for a while. this is done to help keep the testnet chain alive. but then it has been manipulated a lot which means there are times that we don't see any new blocks for a long time and then as the difficulty drops we see hundreds found within a short time.
