Disrupt Decentralized World with Blockchain Testing Services

Blockchain has revolutionized the approach businesses are conducted and provides enterprises the great opportunity to track assets, collaborate and share information. Diverse verticals like retail, finance, and healthcare are reaping the benefits of blockchain distributed ledger technology. The blockchain apps have now gone way beyond crypto-currencies like bitcoin and other decentralized payment modes or systems.


Major Blockchain Architecture Components: How Does it Work?

Consensus (consensus protocol)
A set of arrangements and rules to perform blockchain operations
The smallest building block of a blockchain system (like information, records, etc.)
Particular nodes which perform the block verification process
A sequence of blocks in a particular order
A data structure used to keep a series of transactions which is distributed to all nodes in the network
Computer or a user within the blockchain architecture

Testing is Key to Effective Blockchain Development

Testing blockchain apps is an exceptional challenge with its own technical and theoretical underpinning. The basic blockchain principle is ledger immutability. The smart contract sent to the blockchain has no retroactive impact- it cannot be redeployed or updated, similar to traditional software development. The cost of errors is tremendously high — that is why blockchain testing is crucial for a successful launch of any custom blockchain-powered solution.

ImpactQA is well-equipped with the resources and expertise to ensure that we effectively test all components of the blockchain app as well as the way that they interact with other apps.

Smart Contract Testing

Smart contracts lie at the core of the Blockchain validation method. Smart contract can be thought of as the easiest form of decentralized automation which reduces the requirement for trusted third parties. Smart contracts Test mainly call for simulating all possible unexpected and expected circumstances for all possible contracts. Testing looks at business logic combinations and proper execution of all the transactions in the context of a vigorously changing and expanding the network. This specialized test, if done perfectly, could save heavy costs and effort.

Peer / Node Testing

Usually, a node is any kind of device on the blockchain network with the ability to execute multiple tasks like send, receive, create, or store data along distributed network routes. Peer/Node testing is necessary for maintaining the integrity of the network and shared ledgers. This calls for the test of the consensus protocol to resolve that all the transactions get stored in the proper series. Testing is also performed for nodes that may not pass simultaneously or due to potential network issues or due to nodes not participating in network for different reasons. Peer/node testing helps to establish and maintain the sync between the network and other validating peers.

Along with all these, the testing for block size, the transmission of data, chain size, and testing of cryptographical data are also necessary to Blockchain applications. Given the sheer number of nodes and a range of combinations and transactions that require to be validated, test automation may well prove essential to the success of Blockchain applications. 


Blockchain Testing Tools We Use

The blockchain sector is quite dynamic. QA approaches and tools, testers used yesterday do not work effectively and equally today. One of the major solutions to this issue suggested by our QA team is to develop a custom QA framework with focus on the particular features of a precise project. Our adept QA engineers utilize the QA frameworks like Embark, Populus ,Truffle, Dapple, and many more.

Blockchain Testing Expertise

The testing process involves functional testing to examine the several functional aspects; to enable smart contracts for instance. Expert software testers would also scrutinize the performance of the applications, by discovering possible problems and suggesting possible tweaks to guarantee readiness for launch.

Application Programming Interfaces Testing or API tests will also form a part of the testing process to ensure that the application can handle and format API requests optimally. Integration testing is also significant for blockchain since deployment could be across various environments and systems. Additionally, specialized testing like node and shared ledger testing of all heterogeneous components ensure the smooth operation of the applications. This is significant to test the integrity and security of the system and its invulnerability to potential attacks.

In addition to the above, the new challenges for QA companies are not limited as blockchain technology develops further and is more widely implemented. Software testing companies engaged in ETL and data-centric testing, mobile application testing and other quality assurance services have to remain focus on the additional change in the technology for the sake of their clients, but also their own!
