Blockchain is a shared database store with a constantly increasing list of records known as blocks. Each block has a hash of the initial block and timestamp. A blockchain has the following features: Increased Capacity, Better Security, a Decentralized system, and Authenticity.
There are various blockchains: Consortium, public, and private. In Consortium blockchain, many firms access and have authority over the ecosystem. This type of Blockchain is a fully decentralized system. In the public Blockchain, everyone accesses the network and can participate in consensus. Like the Consortium, it is also a Decentralized System. For the private Blockchain, single firms access and authorize the ecosystem. It is a partly decentralized system.
A blockchain comprises various main components: Node Application, Shared Ledger, Consensus Algorithm, and Virtual Machine. Blockchain is beneficial and effective to users because it is time-saving, cost-effective, and increases security for users.
Industries are widely accepting Blockchains. Due to its increased popularity, crypto users and firms must be ready to adapt testing strategies to blockchain technology. Lack of good practices, development of relevant test information, and handling with scale, performance, and security are significant testing challenges in the Blockchain.
Blockchain testing helps to enable smart records and makes sure fraud security information in the Blockchain is kept in blocks. Transactions in the Blockchain go through encryption and decryption processes that need to go smoothly.
There are several types of Blockchain Testing:
Functional Testing. It tests component systems and their functionality, such as adding a block in the Blockchain, chain size, and block size, among others. Once the transaction’s validity is authenticated, every new block is added.
Integration Testing. It tests the interfaces between components, the integration, and various parts of the system.
“As there are multiple components involved in the blockchain application, integration tests should be done properly and frequently to test that all the components are properly integrated,” wrote the TestProject.
Performance Testing. This Testing tests the performance of blockchain applications, mainly because blockchain applications need good speed.
Node Testing. As the Test project put it,
“A blockchain’s strength is maintained through consensus across all nodes on the order in which the transactions are added to the network. This consensus protocol needs to be tested to ensure transactions are stored in the proper sequence.”
Smart Contracts Testing. It ensures the traders stick to the rules while transacting in the Blockchain.
API Testing. Blockchain causes events to happen in external applications., hence the API. API testing considers the interaction of applications within and outside the blockchain network.
Blockchain Testing Tools
Listed below are some of the crucial Blockchain Testing Tools widely used:
- Ethereum Tester- Ethereum tester is an open-source testing library found on the GitHub repo. Setting up an Ethereum tester is easy, with possible API help for several Testing needs. This is an effective testing tool.
- Ganache- Ganache was initially called Testrpc. This testing tool is widely used to test Ethereum contracts locally, and it functions by spinning up a mock Blockchain. The mock Blockchain gives the tester access to accounts they can use for Testing.
- Hyperledger Composer- It is an open-source tool that assists developers in developing blockchain applications. While using Hyperledger Composer, three types of Testing are performed: automated unit, system testing, and interactive Testing.
