Testing is an Integral Part of in Blockchain Development

1. Blockchain is the concept of decentralization, in which a collection of blocks interconnected, and each one interlinked with previous and successive blocks. Blockchain has a distributed ledger having encrypted and timestamped records linked with previous blocks. In recent times all industries are adopting blockchain applications on their business to avail the secured and efficient business automation. Blockchain is a decentralized platform where every party involved in the transaction able to view the details of it, and only the owner of that data blocks able to update it with the provided private keys. It is vital to know that information once written to the blockchain, and cannot be updated or removed. Hence, testing blockchain apps completely is necessary. Why have proper testing Techniques in Blockchain? The process of the blockchain app should be tested carefully as bugs discovered in one block can modify the entire blockchain. Once a block is added to the blockchain, it resides there always. Changes made to any block in the chain can make the linked blocks void. As a result, it needs a concurrent fix or update. It is impracticable to make such changes later, making it complex in terms of testing. Let us discuss some of the significant techniques for testing blockchain apps. Techniques for testing blockchain applications: Integration Testing Integration testing is fundamental as the different systems have to be integrated smoothly. This is to ensure the different systems have collaborated efficiently while interacting in various instances. Non-functional Testing (Performance) Performance is a significant feature of the blockchain development, as the quantity of transaction and its volume to be tested to know the performance of that block. Blockchain development needs a various set of parameters like performance, production environment, network latency, the sequential transaction on each node, transaction handling

2. speed, and responsiveness of the smart contract. It is complicated to test the multiple endpoints associated with performance testing to improve the efficiency of the blockchain network. API (Application Programming Interface) Testing APIs testing is to check the interaction of the application in and out with the blockchain network. It is to verify the external responses the application receives and secures the validity of the API request setups. These are techniques that are used to check the internal API Smart contract on the blockchain. SoapUI and Postman are two widely used testing tools. Non-functional Testing (Security) Security testing is a very important part of blockchain testing and it is to validate whether blockchain is vulnerable to attacks. The authorization systems are strong, and once authentication is valid, there is no need to think about the integrity, confidentiality, and non-denial of services. Once a transaction started cannot be canceled, hence security testing must expose the identity layer nicks. Other elements associated with security testing are private keys, consensus algorithms, wallet signature, and secure hash. Here is a list of some testing tool used to test the Blockchain app: Testnet indexing tool API testing tools (soapUI and Postman) Bug and test tracking tools Encoding and encryption software Database testing tools Summing Up Blockchain technology is expanding quickly and is opening up possibilities for many industries. Testing should be recognized as an essential part of the blockchain development process to guarantee the scalability of the blockchain ecosystem.
