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. The programming languages discussed in this book are a colorful mix between Python, C++, and C# .NET during the Creditcoin 1.x timeframe and later primarily Rust and TypeScript for version 2.0 and later. Rust is a general-purpose programming language that emphasizes performance, type safety, and concurrency. It enforces memory safety without a garbage collector. Rust is a statically typed and strongly typed functional language and is a popular language for systems programming, including distributed systems like blockchain and also the Linux kernel. For software testers and quality engineers with limited experience working on a blockchain implementation.
