Blockchain Testing: Basics, Future, & The Tools
With many practical applications for the technology already being implemented and explored, blockchain is finally making a name for itself in no small part because of bitcoin and cryptocurrency. As a buzzword on the tongue of every investor in the nation, blockchain stands to make business and government operations more accurate, efficient, secure, and cheap, with fewer middlemen. However, the only thing they tend to miss is understanding how to test blockchain applications?
In this article, we will discuss what blockchain testing is all about, including the benefits and drawbacks, the types of blockchain testing, the phases, and some useful tools. We will also create and test a smart contract using some of the recommended blockchain testing tools with an approach to dive deeper into the concepts of blockchain in software testing.
What is Blockchain?
A blockchain is a distributed database that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. The innovation of a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party.
One key difference between a typical database and a blockchain is how the data is structured. A blockchain collects information together in groups, known as blocks, that hold sets of information. Blocks have certain storage capacities and, when filled, are closed and linked to the previously filled block, forming a chain of data known as the blockchain. All new information that follows that freshly added block is compiled into a newly formed block that will then also be added to the chain once filled.
A database usually structures its data into tables, whereas a blockchain, as its name implies, structures its data into chunks (blocks) that are strung together. This data structure inherently makes an irreversible timeline of data when implemented in a decentralized nature. When a block is filled, it is set in stone and becomes a part of this timeline. Each block in the chain is given an exact time stamp when it is added to the chain.
What is Blockchain Testing?
Testing blockchain applications is the systematic evaluation of the blockchain’s various functional components (e.g., smart contracts). Unlike traditional software testing, testing blockchain involves several components such as blocks, mining, transactions, wallets, and so on, all of which require special tools to test.
Blockchain testing aids in the development of various quality stages, ranging from system performance to the security of the blockchain application.
According to Santu Maity, Enterprise Architect at IBM, the best approach for blockchain testing encompasses the entire environment. This includes blockchain-based applications, both mobile and web, that interact with the blockchain system’s functional component, like an API, smart contracts, and nodes.
Challenges of Blockchain Testing
One of the most significant challenges is a lack of testing tools. Currently, there are few testing tools available for each blockchain framework; therefore, using the wrong tool can cause problems when generating and executing blockchain test cases.
Another issue in the blockchain ecosystem is a lack of professional expertise. Because blockchain technology is still relatively new in the tech world, it has not seen widespread adoption among software developers.
Yet another challenge is testing strategy. Blockchain testing necessitates a thorough knowledge and understanding of how blockchain works. The security of the blockchain network can also be difficult. Blockchain applications are now being used in a variety of economic sectors.
Types Of Blockchain Testing
The following is a comprehensive list of the types of testing a blockchain tester has to perform:
- Functional testing determines the effectiveness of various functional components of the blockchain system.
- Node testing aids in the independent testing of each node on the network to ensure a problem-free connection.
- Performance testing identifies system flow restrictions and recommends an optimal solution.
- API testing contributes to a clear interaction between applications in the blockchain network by ensuring that requests and responses between these applications are properly operated.
Blockchain Testing Tools
Ethereum tester
Ganache
Exonum TestKit
Corda Testing Tool
Truffle
Populus
The Populus framework includes Ethereum’s testing functionality, which is well integrated as a set of properties focused on contract deployment testing. These frameworks are mostly built around the pytest framework, allowing for its very simple implementation.
Manticore
Hyperledger Composer
It has a command-line interface that provides commands allowing you to easily run interactive “smoke tests” to ensure the deployment was successful. This also makes it easy to execute blockchain tests in a CI/D system.
BitcoinJ
The BitcoinJ documentation says it can maintain a wallet, and send/receive transactions without needing a local copy of Bitcoin Core, along with many other advanced features. It's implemented in Java but can be used from any JVM-compatible language; examples in Python and JavaScript are included.
