A Simple Guide to Testing a Blockchain Application

A Simple Guide to Testing a Blockchain Application

Posted By : Pratyush Kumar Singh | 28-May-2019

Blockchain is an emerging technology that gives applications a secure underlying infrastructure, such as for secure payments, supply chain development, and more.

While blockchain is typically thought-about within the context of cryptocurrencies and financial services, it encompasses a wide array of potential applications.

Blockchain grants an unsettled and cost-saving choice to the present consolidated exchange and record-keeping elements that exist in worldwide firms nowadays. Let’s discuss the challenges and factors for testing blockchain-based applications:

Smart Contracts

Smart contracts are major components of the validation technology in a blockchain. A smart contract is a rendezvous of standards as programmable constructs that are practiced in automatically imposing themselves as predefined requirements are satisfied.

The key factors to contemplate while Testing Blockchain Applications are:

  • Approve the techniques for smart contracts equally as in API testing.
  • Validating the methods.
  • Confirming the boundary value.
  • Validating the conditional statement.
  • Testing all the Apis for the smart contract severally.

Security

Numerous layers of security are incorporated with deciding identity. Sadly, once the character layers are hacked, the prompt exchanges can’t be halted. the range of keys might confuse larceny, at the end of the day, something which will be entered can likewise be taken, by shortcomings, for instance, lackluster caching or tools like sniffers.

Some testing ought to be thought about for secure dealing utilizing blockchain by beating hurdles.

The testing factors are as follows:

  • Access and authentication
  • Authenticating data provided
  • Private keys
  • Secure hash, an accord algorithm
  • Wallet signature process
  • OWAPS guideline for web and mobile application
  • Vulnerability analysis

Performance

The performance test needs to be connected to the blockchain as per the perspective of a client application user, reactions needed from smart contracts, and system interfaces.

Also, testing the size of the system and its capability to process transactions is basic, because it permits you to differentiate between software and hardware bottlenecks prior to time.

The key factors are as follows:

  • Performance testing in blockchain incorporates
  • Recognizing execution bottlenecks
  • Describing the metrics for calibrating the framework
  • Surveying whether or not the app is ready for production
  • Anticipated transaction size
  • Network latency counting on block size

Node Testing

The quality of the blockchain prevails in having the shared ledger be exactly identical at every single node, with an identical set and string of transactions.

Testing for flexibility of transactions includes testing the accord protocol to ensure exchanges are saved within the absolute best flow underneath typical conditions and in addition in situations wherever nodes flop simultaneously or enough nodes don’t take an interest within the network for a timeframe.

The key factors are as follows –

  • Every single heterogeneous node ought to be autonomously tested.
  • Validate the block for its legitimacy to create a prolific transaction.

Block Size

Block size will most likely fluctuate on the basis of the utilization of the blockchain. Consequently, the payloads within the block will dissent in value.

Keep in mind that different exchanges are often allotted to 1 block. the very fact of the matter is, testers ought to assess:

  • How dynamic block size affects performance?
  • By what suggests that the block can be managed?
  • What happens once the number of recent data going into a block surpasses the utmost block size for that blockchain application?

Conclusion

Testing Block Chain Applications are terribly distinctive in regard to testing customary apps. And additionally to any or all the standard problem-solving techniques, we want to contemplate things like:

  • how our application will operate once incidents outside of our control influence the system?
  • if people will front-run our exchanges,
  • and also, whether or not our transactions can turn out to be too pricey, making it not possible to allow the presence of our application.

This is solely the beginning of a list of potential testing challenges for blockchain applications testing. Testing needs to transcend.
