Blockchain: A Complete Overview
In this week’s blogs will be moving our focus to Blockchain testing. Defined in the dictionary ‘blockchain’ is a network of interconnected computers utilising a peer-to-peer system to store transactional data from cryptocurrencies.
What is Blockchain Testing?
We have explored the definition of blockchain , but what exactly is blockchain testing? Blockchain testing involves verifying the functionality, security, and performance of blockchain applications and networks. Given the unique nature of blockchain technology, testing is crucial to ensure that the decentralised, immutable, and distributed aspects of a blockchain system work as intended.
What Types of Blockchain Are There?
There are typically three types of blockchain: consortium, public, and private. Consortium blockchain involves a decentralized system where multiple organizations hold authority over the network. Public blockchain offers decentralized access to everyone, while private blockchain provides partial decentralization and restricted access to specific organizations.
Approaches to Testing Blockchain
API (application programming interface) – Testers must validate the correct handling of API requests and responses within the blockchain ecosystem.
Functional – In our previous discussion on functional testing, we learned that it ensures functional user specifications and requirements are met and functioning properly. This testing method evaluates various components within the framework by examining specific business processes, user scenarios, and behaviours. Key components typically tested include block size, new blocks added, chain size, and data transmission.
Performance – As discussed a couple of weeks ago, performance testing assesses system performance against predetermined benchmarks. In blockchain testing, this process identifies any performance bottlenecks and analyses system metrics to determine readiness for deployment.
Shift Left – This testing approach is implemented early in the software delivery process to proactively identify and prevent issues.
Blockchain technology offers a transparent means of maintaining data records, representing a fully democratized system. Beyond secure payment applications, its popularity continues to soar, making blockchain testing a crucial aspect. For further information, reach out to us today.
Tools for Blockchain Testing
The last point of a blockchain plan begs the logical question of testing tools available on the market. The following are a few tools that help in testing blockchain applications and guarantee they function properly.
Ethereum Tester – Known as one of the most widely used platforms for creating blockchain applications, Ethereum comes equipped with a range of tools that support both app development and testing. It proves dependable for Web3 Integration, API, Smart Contracts, Backend, and various other blockchain testing scenarios.
Hyperledger Composer – This innovative open-source tool provides a means to model and test your blockchain network using a minimal toolkit including Docker and a browser. Utilizing Hyperledger Composer, the process of blockchain development is simplified through a modeling language, user interface, and command-line interface. It enables automated system tests and interactive testing for a seamless experience.
