Blockchain Testing-All You should know about Blockchain

Blockchain Testing

This blog is meant for the people who are interested to grab the knowledge about BlockChain Technology or want to know the scenarios which we can test as part of BlockChain Testing. Following will be the Topics for this blog:

• What is the meaning of BlockChain?
• Features of Blockchain
• Type of BlockChain
• Components of BlockChain
• How Does Blockchain Work?
• Phases of Blockchain Testing
• Challenges in Blockchain Testing 
• Blockchain Testing Tools

What is Blockchain?

Blockchain is a distributed database store growing list of records, called blocks. Each block contains a hash of the previous block and a timestamp. 

Features of Blockchain includes

• Decentralized System: Beneficial in Various Industries like finance, real estate Etc.
• Better Security: Uses multiple nodes to complete and authenticate transactions
• Authenticity: This allows the unique algorithm to process data
• Increased Capacity: Increases the capacity of the entire network

Type of Block Chain

Difference in Public, Private and Consortium Blockchain

Components of Blockchain

How Does Blockchain Work?

Phases of Blockchain Testing

Challenges in Blockchain Testing

• Lack of Best Practices-Lack of skills in Blockchain applications is one of the biggest challenges. Learning additional skills or understanding the best practices to implement Blockchain applications are expensive
• Blockchain Testing Tools- Blockchain applications testing is all about tools. Selecting the right tool as per application need is one of the crucial decisions.
• Block and Chain Size- Along with standard testing, tools and the best practices in place, testing for block size and chain size are also important. improper validation of block size and chain size may cause failure of Blockchain applications.
• Performance and Load-Failure of performance and load testing gives little or no insight into how the Blockchain application performs under specific workloads and network conditions.
• Security- Lack of security testing leads to developing Blockchain applications that may be attacked at network level, user level and mining level.

Blockchain Testing Tools

• Ethereum Tester: It is an open-source testing library available on GitHub repository. It is easy to install with manageable API support for various Testing requirements.
• Ganache: Ganache, which is earlier known as Testrpc, is the most-used library for testing Ethereum contracts locally. This testing tool works by spinning up a kind of mock Blockchain that gives you access to accounts you can use for Testing.
• Hyperledger Composer: Hyperledger Composer is an open-source tool that helps developers to build blockchain applications. There are some features that help in Testing as well. Using this tool, we can perform mainly three types of testing: interactive Testing, automated unit testing, and automated system testing.
