Blockchain Testing: What Exactly Can You Test?

The innovation we know as blockchain is one of the most significant inventions in the 21st century. Its technology has become so popular that it has developed a domino effect that has impacted many sectors such as healthcare and manufacturing.

One sector that is starting to explore and grow on blockchain’s capabilities is quality assurance in the form of blockchain testing.

What Is Blockchain From a QA Perspective

First of all, blockchain can be utilized by QA specialists as a means to process payments digitally in a safer and more secure environment. This is made possible due to the different verification parameters involved for transactions employing this technology.

Another way the QA sector can use blockchain is by decreasing the costs and settlement time for transactions. Also, quality assurance services can be more transparent as it eradicates the requirement for third parties thanks to the secure ledger provided in the blockchain.

Furthermore, the QA sector can also employ blockchain technology to accomplish thorough testing of a product before it is introduced to its target audience. The ability to conduct blockchain QA testing could be the difference between a product succeeding or failing in the market.

Here are a few of the numerous benefits the QA sector can experience:

  • Numerous applications: Thanks to its revolutionary technique in processing transactions securely, blockchain technology has the capability to improve the safety, functionality, and abilities of many organizations in the QA sector.
  • Importance of security: Since blockchain technology needs every user and all of its transactions to stay anonymous, transactions that go through here have improved security. Furthermore, blockchain also combines encryption which makes it a safe environment for different processes.
  • Functionality is important: The technology leverages a functional blockchain testing framework to assist assess and decide if a smart contract is viable.

What Can You Test In a Blockchain?

To give you a more in-depth idea of how to test blockchain and how it operates, check out these aspects below of what you can test employing this technology:

  • Block size: Each block in the blockchain only has a maximum size limit of one megabyte but recent innovations have directed to potential transactions going past this boundary. QA testers can leverage blockchain testing tools to see how a block operates if it goes past the 1MB limit.
  • Chain size: Although there are no limitations to the chain size in blockchain, it’s still likely for QA staff to test for performance and functionality to see how far it can reach.
  • Smart contract testing: QA specialists can test smart contracts to see if all business logic combinations and their respective triggers will lead to the suitable execution of specific transactions.
  • Load: The blockchain continues to increase each day and the load it can endure is beginning to strain. Testing for load capacity would be an intriguing project for QA testers to see how transactions will push through in case of overload.
  • Security: Testers can also conduct security tests in the blockchain specifically since there are many costly assets stored in this network.
  • Transmission of data: Data transmission is another aspect of testing the blockchain to assure that all details remain anonymous while smart contracts remain secure.
  • Peer/node testing: The shared ledger that is created publicly available in the blockchain is the basis of what makes this technology work. That’s why QA specialists can test for consistency of all transactions that move through here to guarantee validity.
  • Crypto graphical data: Crypto graphical data is important in the blockchain network so it is only functional to test that all data that goes in and out is encrypted and decrypted accordingly.
  • API testing: External events or actions can start activity in the blockchain which is why API testing is required. One way API testers can work is to confirm that application interactions in and out of the blockchain are accurate with no redundancies involved.

Checklist for Effective Blockchain Testing

Blockchain QA involves a combination of several testing procedures, each of which offers various possibilities:

Functional Testing for Blockchain Systems

Testing for the functionality of blockchain systems is possible for QA specialists to execute. The following functional tests that can be done include:

  • Unit testing for smart contracts: Blockchain testing with references to smart contracts is possible and can be accomplished by assessing all parts of a given contract. QA testers will require to take into account and predict all possible scenarios that would happen in case the logic of each contract is pushed to its boundaries.
  • API testing: API is an interface that lets programs function in conjunction with one another seamlessly. To understand how to test blockchain applications, developers employ special software and tools to assure precision in data output.
  • Integration testing: Integration testing lets testers pinpoint mistakes within integrated interactions. This is specifically true since applications are unable to work by themselves.

Non-Functional Testing of Blockchain Applications

In non-functional testing of blockchain applications, the approach leans more towards validating procedures to assure productivity and security.

  • Security testing: Apart from reviewing for potential cybercriminal activity, QA testers can also identify any potential difficulties from the system itself that could put the assets of blockchain users at risk.
  • User interface testing: UI testing is when developers review to ensure that the end-user functionality is fulfilled by conducting tests on reliability and continuity of the final product.
  • Performance (load) testing: Load testing is created to see how a product will perform despite heavy load in the system. This type of testing creates a great blockchain testing tutorial for new testers.


Blockchain technology is one of the most revolutionary innovations developed recently, and it persists to grow in usage each day. People have discovered many applications for the blockchain environment, with quality assurance testing being one of the more recent sectors to embrace the technology.

The information provided in this post should deliver businesses with an idea of how they can leverage the blockchain to grow their QA testing for different applications. What makes blockchain testing even better is that there are amazing tools available for QA specialists to carry out their tests.
