All you need to know about Blockchain Testing

Blockchain applications are not similar to most applications on the market. While the performance, functionality, and user experience of a blockchain application usually parallels other applications, the structure of its data system appends added level of complexity when it arrives at QA testing. So much so that it needs appropriate tests to be conducted, specific tools to support the testing process, and specific skills for your QA testers to gain.

But what is blockchain testing? What is blockchain employed for? Why is it critical to perform blockchain QA testing? And how does somebody begin to test blockchain applications?

What is Blockchain Testing?

Blockchain is a digital data structure that endures in many places together because of its dependence on a peer-to-peer computer network. The data inside a blockchain is decentralized, indicating that a copy of the blockchain endures on each computer within the network. Each addition to the blockchain can be observed over the network, with transactions cryptographically attached to the previous transaction, making it hard to pull off the fraud.

So, what is blockchain testing? In short, blockchain testing is the method of testing the blockchain application to validate the security, functionality, and performance of the digital data structure.

Blockchain testing needs managing a secure testing environment while operating remotely or onsite as well as QA engineers with great knowledge of blockchain testing frameworks and experience with blockchain testing tools.

Why Blockchain QA Testing Is Important?

Within the technology of a blockchain are smart contracts, or collections of rules given out through programming that are automatically executed when predefined conditions are satisfied. And it’s the enforcement of these smart contracts that verifies the importance of blockchain QA testing.

Unlike most data structures, once a smart contract is disposed to the blockchain, modifications can never be made. In order to stop a mistake that can never be eliminated, it’s up to your QA testers to execute comprehensive and quality tests.

What happens when a bug is detected in production? The smart contract can’t be renewed or rolled back. A new version of the smart contract must be designed and deployed. And new versions of existing smart contracts must be manually built by applying the previous data into the new contract all over again—an effort expensive in time and resources.

Points to consider before testing applications based on the Blockchain technology

  • Testing environment: Transaction completed in the blockchain changes its present state. so as to feature or alter any entry, miners’ resources are required. Miners are those who charge expenses for verifying transactions and adding them to the blockchain. That’s why it should appear to be too overpriced to conduct tests within the live surroundings.
  • Transactions are permanent: All blockchain-based apps are limited. It is the main idea behind them. Decentralization indicates there is no central entity that is controlling the system. Decentralization indicates that the application lives on several systems and its code are available to everyone. As there is no central repository, it is not likely to reverse 99 percent of defects, errors that make it to the blockchain. Therefore it becomes very crucial to make certain all transaction info is accurate before transferring it to the system. Any defect which has been neglected will be crucial. It performs the work of the QA more and more responsibly.
  • Every transaction is a paid transaction: This statement is in association with the first. The responsibility of the tester is to assure that the transactions adding and saving within the network are error-free. Because any transaction in the blockchain needs the charge, however, this makes the testing process very accurate.

Here’s How to Test Blockchain Applications

Set your testing up for success with a solid blockchain testing framework sent out by QA professionals experienced with blockchain testing tools and decentralized data architecture. From blockchain penetration testing to security testing, assure that your testing process involves each crucial test case for successful, safe deployments.

When it comes to blockchain testing, your QA team may depend on Agile and DevOps practices to improve the quality of their development and testing purposes. Through a shift-left procedure, your QA team can conduct a kind of test early in the development cycle and reuse those tests time and time again. This early feedback reduces the bug count later in the development method.

We recommend that QA teams incorporate these primary tests within their blockchain testing framework.

API Testing

How well does your blockchain application communicate with internal and external applications? Since blockchains can send events, blockchain activity can be triggered by events from outside systems or outside calls.

Transactions must be verified against specific rules to create an order for the blockchain to distribute. The API then gets a confirmation that the blockchain has obtained new data for this transaction.

To follow API testing automation best practices, verify the interaction of APIs in and out of the blockchain at every step of the process. Blockchain testing tools, as well as external API testing services, can confirm that API requests and responses are formatted and managed correctly.

Functional Testing

Evaluate all business circumstances and methods as well as the effectiveness of all use-case situations. QA testers should also examine block size, chain size, data transmission, and the ability to add blocks to verify the functionality of the blockchain application.

Security Testing

Is your blockchain application fully adjusted to withstand attacks, including viruses and malware programs? Any outgoing transaction or transfer of data cannot be discontinued, so QA testers must reveal any potential threats through security testing. Your QA testing process should also verify that the blockchain system stops processing any incorrect or damaging data before it creates consumer risk so that users always associate with a safe, healthy digital application.

Penetration Testing

Cyberattacks and fraudulent hacking are very hard to do within a blockchain—that is, when the appropriate software rules and smart contracts are in place. Yet, any mistake within the complex math or software rules can leave the front door open to unlawful users with malicious intentions.

Blockchain penetration testing enables your QA engineers to build and execute test cases alike to the behavior of cyberattackers—without the malicious intent, of course—in order to confirm that the blockchain blocks out any unlawful user. They incorporate blockchain penetration testing that affects real-world scenarios by trying entrance through network service, social engineering networks, wireless networks, and the blockchain application.

Performance Testing

Thorough blockchain testing should involve examining performance metrics, recognizing performance bottlenecks, and evaluating the application’s readiness for consumer use. It’s essential for your QA testing process to check the sequencing of transactions at each node, dependency on the production environment, transaction processing speed, and any network latency. Many performance test cases can be performed through blockchain testing tools and, when additional resources are needed, with the help of a performance testing services provider.
