To secure, store and manage digital identity and data, organizations across the globe are looking for a secure platform that protects their data which is spread across multiple providers. Blockchain is the solution!
To guarantee trust, testers must ensure that all the components of a blockchain are working perfectly and that all applications are interacting with it in a trusted manner. Some of the core tests that should be run include functional, performance, API, node testing, and other specialized tests. So here is what they entail in a nutshell:
- Functional testing. This is a holistic process that evaluates the work of various functional parts of the blockchain (e.g. smart contracts).
- API testing. Application Programming Interface tests address the interaction between applications in the blockchain ecosystem. It checks to ensure that API requests and replies are formatted and handled properly.
- Performance testing. It identifies performance bottlenecks, suggests the methods of fine-tuning the system and reviews if the application is ready for launching.
- Node testing. All heterogeneous nodes on the network must be tested independently to ensure smooth cooperation.
Here are 5 popular tools for testing your blockchain applications:
- Ethereum Tester: It is an open-source testing library available as a Github repo. Its setup is pretty easy with manageable API support for various Testing requirements.
- BitcoinJ: It is a Java-based framework built for Bitcoin-based apps that enables you to interact with the real BTC network and various testing activities. In order to use it, you don’t have to download the standard BTC Core files from Bitcoin.com. You can even approach a user forum in case you need clarification or are facing hiccups in the testing process. It is an open network available for assistance.
- Populus: This framework has the testing functionality of Ethereum embedded in the form of a set of features for test contract deployment. It’s developed around the py.test framework. Hence, it is relatively easy to implement.
- Truffle: It’s a commonly referred name for Ethereum developers, which brings in good testing features, such as automated contract testing. The framework holds capabilities beyond just testing functionality within the Blockchain application.
- Embark: It is a testing framework that focuses on developing decentralized applications (dApps) that run on various systems or nodes. It has integrations with Ethereum blockchain, IPFS, and decentralized communication platforms such as Whisper and Orbit.
Challenges in Testing Blockchain Systems
Given the relative newness of the technology, there is still very little in the way of formal best practices or testing tools around blockchain technology, though this is something that is rapidly changing with a lot of new up-and-coming frameworks in this area. When I started making sense of blockchain systems and how to approach testing them, part of the initial challenge was the limited scope of examples I can learn from and established frameworks in place.
Testing a blockchain is vital to ensure the defects in a decentralized ledger are eliminated. This ultimately protects a business against the negative consequences of blockchain poor operation. There are many blockchain testing tools available on the market, including development frameworks with testing capabilities. The final choice would depend on your development strategy and the test types needed for your app’s uninterrupted functioning.
