Blockchain is a digitized, distributed ledger which is shared, replicated and synchronized among the members of a public or private peer-to-peer computer network comprised of its user machines. The ledger permanently records the history of asset exchanges amongst the members of the network in a linear and chronological order. Every transaction recorded in the ledger has a timestamp and unique cryptographic signature associated with it. Once the information gets stored in the blockchain, it cannot be changed or tampered. All the confirmed and verified transactions are combined into a block and chained to the most current block to form a blockchain.
Testing blockchain-based applications is challenging because there is a significant change in the technology itself. Besides all requisite testing: functional, integration, security, performance and specialized testing; blockchain testing requires smart contract testing, node testing, and advanced level non-functional testing.
