Regtest
Regtest is a testing blockchain for regression purposes. Unlike testnet, regtest is not a public blockchain. Regtest is a blockchain that can be created by a user for local testing purposes. This is ideal for testing features that don't need to interact very much with the network. You can create your version of the blockchain with a local genesis block. Similar to testnet, a regtest flag is added to the command to launch the process:
$ bitcoind -regtest

$ bitcoin-cli -regtest generate 500
