Tools for testing Blockchain application development

Blockchain technology architectureBlockchain applications are developed widely today and we will discuss the tools required for testing blockchain applications in this blog.

In 2008, a person came with a mask of anonymity and unleashed a powerful tool into the world:  Bitcoin. Or rather, Cryptocurrency in general. It was met with raised eyebrows and suspicion.

Ten years down the line and thousands of other cryptocurrencies later, the buyer of bitcoins made gold mines out of it and when this was publicised, the frenzy began and the common man’s obsession began.People dug deeper into the technology behind bitcoins and found out a new treasure trove  –  ‘blockchain’  technology.

Huge amounts of money is being drained by companies worldwide into harnessing blockchain technologies into main line business world.Blockchain applications are developed these days to serve many purposes, ranging from contracts to notaries and  bookkeeping. As with software development, blockchain development also need testing.

In this blog, we shall discuss about the tools required for testing Blockchain Applications.

Key Testing Types 

1. Functional testing 

This includes the evaluation of the functional parts of a blockchain, like smart contracts.

2. API testing 

API tests interaction between the applications in the blockchain ecosystem. The tester also ensures that API requests and replies are handled properly.

3. Performance testing 

Any bottlenecks or lags in performance are identified and methods for fine tuning the system suggested and reviews are given if the application is ready for launching.

4. Node testing 

All the heterogeneous nodes in the network are tested independently to ensure smooth co- operation between the nodes.

Agile practices are followed in testing blockchain applications., out of which the  shift left approach to testing is fast gaining popularity. A series of tests are carried out as early as possible in the development cycle so that occurrence of defects can be minimised which could otherwise pop up in the later stages of application development when it can affect the business in a much more grave manner. 

Blockchain testing tools 

  • Ethereum Tester

Ethereum is the most widely used platform for developing blockchain applications and testing them. Ethereum tester is API, Web3 Integration, backend, smart contracts and several other blockchain tests.

  • Ganache (previously TestRPC) 

This testing tool is used to test Ethereum contracts locally. A stimulated blockchain is created which allows anyone to use various accounts for testing. The results will be satisfactory, but not completely perfect since the testing results are obtained from a simulation and not a live event.

  • Hyperledger Composer 

This tool is beneficial for testing blockchain features before they are launched. The main areas of application are interactive, automated system and automated unit testing.

  • Exonum Testkit

Exonum Testkit tests the operation of the entire service . it enables the testing of API, transaction execution in the synchronous system devoid of the involvement of network operation and consensus algorithm.

There are various other tools in the blockchain environment include BitcoinJ, Corda Testing Tools, Manticore, Populus and many more.

Testing of blockchain ensures that there are no defects in decentralised ledger. The selection of the right type of blockchain testing tools would depend upon your development strategy and the types of tests that your app would need for smooth functioning.
