Test network
A test network exists to help facilitate and increase adoption of the Ethereum blockchain. They are the exact replica of the main network. Using these networks does not cost anything for deployment and usage of contracts. They are completely free of cost. This is because test Ethers can be generated using faucets and used on these networks. There are multiple test networks available at the time of writing, such as Ropsten, Kovan, and Rinkeby.
