Testing the Creditcoin Blockchain: A Daily Account from a Test Engineer’s Perspective

Follow the quality engineering journey of the Creditcoin blockchain across four distinct implementation versions and a myriad of technologies. Through the eyes of a test engineer, this book discusses testing implementations with the Hyperledger Sawtooth and Substrate frameworks, testing switch from proof-of-work to proof-of-stake consensus algorithm, and testing an Ethereum Virtual Machine compatibility layer.

You’ll traverse several years of fast-paced multiple blockchain implementations and technological changes including an explanation of all major components involved, and the approach taken. You’ll also look at examples of test automation approaches and tools, interesting bugs, and testing challenges.

Most everything discussed in Testing the Creditcoin Blockchain is open source, ensuring easy access, and multiple references to source code and GitHub are included throughout.

You will:

• Study the many of the components of a distributed blockchain network.
• See how components work and where testing can be plugged into a distributed blockchain network environment.
• Glimpse into the daily blockchain testing activities of a principal test engineer.
• Become familiar with a fast-paced technical software development project.
