Top Tools for Testing of Blockchain App in 2021


With the emergence of one of the best technologies named Blockchain in the market, the IT world has completely transformed. There have been some serious developments in the market that involve the supply chain of data, people, numbers, and data. The majority of software testing companies have now started to embrace blockchain technology because of its highly prospective nature. Blockchain is a very effective technology when it comes to catering to various testing requirements and this is the main reason why QA companies are curious to gather more and more knowledge about blockchain.

There is no denying that blockchain is one of the most revolutionary technologies in today’s time and it can shape various industries in the future. But when it comes to hiring an expert for creating a blockchain app or testing blockchain applications, the expense will depend on their knowledge. Therefore, many companies aren’t able to have blockchain applications without perfect testing. So, the testing companies list such problems as challenges and wish to have access to blockchain application testing for stability and quality.

Nowadays, companies have expertise and resources that can help in testing blockchain applications and offer clear insight into the importance of blockchain security testing and the tools that are used for testing blockchain apps. In this blog, we will learn about such tools and see how it works.

What is Blockchain Technology?

Blockchain is a popular system that is used to record all the business information in such a manner that it makes it impossible for anyone to hack, cheat, or change the system. Blockchain is an essential digital ledger of contracts and transactions that are distributed around the network of computer systems with the use of blockchain.

Each block size and chain depends on the transaction level. Each chain has various transactions, and whenever a new transaction appears on the blockchain, a record of that new transaction gets added to the ledger of every participant. The decentralized database that various participants handle is popular as Distributed Ledger Technology.

Blockchain is nothing but a type of DLT that can easily record transactions with a cryptographic signature known as a hash.

This clearly means that when one block in one chain is tempered, it can immediately show that the data has been changed. So, if the hackers try to corrupt the blockchain app then they will have to change every block and chain size of the system, or else they can be caught easily.

Besides, other blockchain technologies like Ethereum and Bitcoin are constantly growing as new blocks get added to the chain. And this can add to the security of the ledge.

What is the Process of Blockchain Testing?

The testing process of blockchain apps involves functional testing to analyze various functional aspects. In this procedure, the testers investigate the performance of the application by spotting possible problems and offering necessary tweaks that can favor its readiness. Some other segments of blockchain app testing include –

  • API (application programming interface) testing assures the testing teams that the app can handle and format all the API requests.
  • The shared and node ledger testing covers all the heterogeneous components that can ensure that the functions of the app are perfectly streamlined.

Top 8 Blockchain App Testing Tools

Some of the most popular blockchain applications testing tools are –


BitcoinJ is one of the most popular tools for testing blockchain applications. It is a Java-based product built for Bitcoin-based apps. This framework enables interaction with various testing activities and the real BTC network. If any tester wants to use this tool, he doesn’t need to download the standard BTC Core files. He can easily contact a user forum when any clarification is required for the testing process. BitcoinJ is a very popular open network available in the market for assistance.

Features of BitcoinJ

  • API contexts
  • Works with smart contracts
  • Works with the payment protocol, BIP70
  • Works easily with micropayment channels
  • The tester can use BitcoinJ from other languages like JavaScript, Python, Ruby, C++, and more.
  • BitcoinJ itself does the coding conventions in the library


Populus is a framework that comes with the testing functionality of Ethereum embedded. It comes in the form of a bunch of features that can carry out the test contract deployment process easily without any effort. Populus is a tool created around the pytest framework. And this is the reason why Populus is relatively easy to use and implement.

Features of Populus

  • Transparency
  • Accessibility
  • Liquidity
  • Universality
  • Security

Ethereum Tester
