Unlocking Potential: The Role of Test Automation in Blockchain Development

Blockchain technology is one of those slowly thriving technologies. It has recently gained momentum, fundamentally integrating and revamping the entirety of ecosystems belonging to various industry niches. Last year in 2023, the blockchain market value was estimated at $19.36 billion. Moreover, a survey stated that despite challenges faced by the technology, 90% of businesses were able to adapt in some ways. The (block) train does not stop there, 87% of those businesses are ready to heavily invest in blockchain starting in 2024. Now this does tell a lot about how the technology is growing in every investor, business, and industry. 

The reason is the transparency and scalability offered by blockchain technology based solutions. It creates this Trust Ecosystem, which helps companies to trace the data, assets, and gazillion amounts of information across a dedicated network. But of course, every solution faces challenges and setbacks, to counter those setbacks we also have to develop a rational approach; Test Automation. The blog discusses the role of test automation in blockchain development and explores its importance in great detail.

Challenges in Blockchain Testing

Every blockchain developer wants his/her code to attain perfection. Whether it's in terms of UX or its functionality, the reason perfection matters is technology has become an integral part of our operations, industries, and operations. To achieve that level or standard, to become important for users, developers need to test their code before deploying it to the masses. 

Launching a product without clearing the testing phase jeopardizes the solution’s ability to help people and perform its functionality. 

However, unlike any traditional app product developing and testing blockchain solutions is not that straightforward. These challenges vary depending upon their complexity level and developers need to adapt different kinds of testing methods to overcome them.

Immutability: Blockchain solutions naturally are immutable. The data cannot be altered, hence you need to perform a test before launch, The post-launch test may be highly complex.

Decentralization: A blockchain needs to be a reliable and scalable network. Testing every node is crucial at the same time a challenge too.

Integration with Diverse Ecosystem: Testing before integration to ensure smooth operation between other systems is a must task. But again it's like a big obstacle of complex challenges for every developer.

Benefits of Test Automation in Blockchain

When a developer opts for or considers manual testing for a blockchain system, they might face numerous other hindrances. Now these hindrances affect the development process, its pace, and maybe cost too at some point. However, automating the testing phase unlocks benefits that eliminate these frictions and make entire project deployment smoother. 

Time

Budget and time are two correlated attributes irrespective of the project's scale. The resources involved and utilized need to be considered extremely important if they want to achieve superlative results. Test Automation in blockchain impacts these two parameters heavily. By reducing manual labor you save time and resources, which will affect your overall budget. 

Consistency

Maintaining consistency in a testing environment is achieved by replacing traditional approaches with automated ones. Doing so developer is also supporting the continuous integration and deployment pipeline, empowering it with efficiency too. Every small factor that improves the consistency of a project whether it's related to testing or deployment, guarantees stability. 

Preset

Our testing approach is to support the fact that prevention is better than cure. To do so, we have to streamline the feedback loop, address early bug detection, and provide a regression testing model. Automation achieves that conveniently, moreover, it also increases the test coverage and thoroughly identifies problems that lie at the extremes of the system.

Types of Test Automation for Blockchain

Here are the types of test automation for your blockchain solutions. Each testing approach plays an incredibly important role in ensuring that you as a client benefit in every way possible. 

Unit Testing

Image a Blockchain solution as a cake with its unique elements and ingredients that elevate the taste altogether. But before putting the cake together, pastry chefs always make sure to taste each ingredient separately. Just like a cake tasting, for a blockchain solution, you need to test every component separately. Every piece of code is tested, but that does not consume a lot of QA time. You see, the method only aims to test small pieces of code that are crucial for making the whole solution work. So in terms of complexity, it's easy. 

Functional Testing

In the functional testing phase, the application or a solution is tested as a whole. A QA is aiming for answers to the questions like:

Does this solution meet your overall requirements?

Will it need feature updates?

Are my clients' users engaging with the solution experiencing difficulties?

The test focuses on every and all the functionalities of a solution. You require a few setups including tools, frameworks, and methodologies making it more intense compared to Unit testing. 

Integration Testing

Functional testing is not as complex as integration testing, but it dives deeper and selects niche components. These components need to synergize and work together making sure your solution is working with optimum performance. Blockchain Quality Analysts are supposed to focus on the general components given below: 

• Data Integration

• Modules and Classes

• Third-party libraries

• APIs

Automating such a time-consuming and cost-consuming process allows your solutions to score perfect points conveniently. Additionally, interoperability affects user interaction too, so QAs need to make sure they are well-refined to explore that part proficiently.

Security Testing

A network working with a high volume of information and data-based assets cannot be vulnerable to attacks. The fundamentals of blockchain include security, scalability, and transparency. There is no bargain here, so employing various security testing approaches like those given below is highly important for the success of your project.  

Penetration Testing: Simulating real-world cyberattacks.

Smart contract Auditing: Reviewing code for bugs, vulnerabilities, and errors.

Cryptography review: Analyzing encryption algorithms.

Consensus mechanism analysis: To make sure that transactions are validated. 

The testing phases are tougher and a higher level of standards are considered due to its importance in the solution.

Performance Testing

Blockchain technology-enabled solutions are built to work in a plethora of scenarios and conditions. Through all those conditions and scenarios the solution has to maintain a performance spike. Here the testing can greatly affect these performance characteristics mentioned below: 

Reliability: Again without failure or crashes the solution needs to reliably work under various conditions. 

Concurrency: Your solution is built on a blockchain network, it handles a lot of transactions simultaneously. A slight performance degradation or contention can cause a fortune to your users. 

Fault Tolerance: Even though there is hardware failure, software failure, or related disruptions, your solution has kept operations running. 

Scalability: Looking at how innovation is pacing-up at every moment, scalability becomes essential. Increasing user demands can be satisfied by testing the scalability of your solution.  

Stress and Load: Determine the resilience and stability of your solution as it may face peak load conditions or extreme ones from time to time. When there are peak load conditions your solutions cannot go overboard, so need to optimize the blockchain ecosystem accordingly. 

Tools and Frameworks for Test Automation

The Impactful Conclusion

Automated testing empowers QAs to achieve three of the primary goals required while building any solution. They are efficiency, quality, and cost, ultimately you as a client need to keep in mind factors that impact your project's success rate. As you were moving to the bottom of the list there were two things we observed; One the complexity level of those automated testing methods was increasing and so was their importance. However, by leveraging the help of a blockchain development company, you achieve improved efficiency, and cost-effectiveness, and speed up your solution’s every stage for the users.  

Automated testing of blockchain solutions can help your idea to achieve high-quality standards. On top of that it effectively delivers your users a satisfactory experience. The fact that experts won’t counter, instead encourage you to use automation shows how incredibly useful it is for your solution. Embracing automation will help you unlock the true potential of blockchain technology.
