Richard Johnson

Beschreibung

"xUnit Principles and Practices""xUnit Principles and Practices" provides a thorough and authoritative guide to the design, evolution, and application of xUnit testing frameworks across modern software development. Beginning with the conceptual origins of xUnit in the Smalltalk SUnit lineage, the book explores the foundational principles that have shaped automated testing for decades. Through detailed insights into the test cycle, assertion models, and cross-language design patterns, readers gain a strong understanding of the architectural decisions underpinning xUnit and its prominent implementations such as JUnit, NUnit, xUnit.net, and pytest.The book systematically unpacks the internals of xUnit frameworks, from test runner architecture and fixture management to extensibility via plugins, integration with CI/CD pipelines, and advanced error diagnostics. Practical strategies are presented for designing expressive assertions, implementing robust mocking techniques, and maintaining test clarity and stability—even at scale in large projects or distributed, cloud-native environments. Real-world examples and anti-pattern remedies ensure that both test novices and veterans can create maintainable, efficient, and reliable automated suites adaptable to evolving software systems.With dedicated chapters addressing security, compliance, observability, and the future of automated testing, "xUnit Principles and Practices" serves as both a day-to-day reference and a forward-looking roadmap. It bridges technical depth with actionable guidance—empowering engineers to automate quality processes, manage risk, and adopt emerging testing innovations. Whether aligning with enterprise delivery requirements or exploring new trends in AI-driven test maintenance and telemetry, readers will find this book an indispensable companion for rigorous and effective xUnit testing.

Evidence of the Afterlife - The...

Jeffrey Long, Paul Perry

“There is currently more scientific evidence to the reality of near death experience (NDE) than there is for how to effectively treat certain forms of cancer,” states radiation oncologist Dr. Jeffrey Long is his groundbreaking new book Evidence of the Afterlife. In 1998 Dr. Long and his wife, Jody, began the Near Death Experience Research Foundation with the goal of creating a forum for near death “experiencers” to share their stories. Grounded in first-hand evidence culled from over 1,600 verified NDE accounts, Evidence of the Afterlife presents the strongest argument yet for the underlying truth of those who have died and returned to share their tales.

OpenAI Meets OpenClaw AI...

Ryan Foster

This audiobook is narrated by an AI Voice.
Stop Switching Between ChatGPT and Claude. Build One Smarter AI Assistant That Uses Both.
Are you tired of paying premium prices for simple questions while getting basic answers for complex analysis? Most businesses waste money by forcing every AI request through the same expensive model, regardless of task complexity.
OpenAI Meets OpenClaw AI Assistant shows you how to build a hybrid AI agent that automatically routes work to the right model for the job. One assistant, multiple brains, zero coding required.
Written by enterprise solutions engineer Ryan Foster, this step-by-step guide teaches non-technical professionals how to combine OpenAI's GPT models with Anthropic's Claude using OpenClaw as your no-code hub.
What You'll Learn:
Install OpenClaw and connect both OpenAI and Claude to create a unified assistant that thinks smarter. Master intelligent routing so support questions go to fast, cost-effective models, while strategy work gets handled by advanced reasoning models. Implement channel-based routing for Slack, web chat, and API integrations without writing code.
You'll discover the three-lane approach to AI model selection, learning when to use lightweight models for quick answers and when to deploy extended thinking capabilities for deep analysis. The book covers practical cost control through token management, OpenRouter integration to access dozens of models via a single API, and troubleshooting techniques when routing doesn't work as expected.
Perfect For:
Business professionals who want smarter AI tools without programming knowledge, teams looking to optimize AI costs while improving output quality, and anyone frustrated by the limitations of single models. You'll also benefit if you're evaluating AI solutions for your organization or want to understand hybrid AI systems without technical jargon.

This Is What Inequality Looks Like

Teo You Yenn

What is poverty? What is inequality? How are they connected? How are they reproduced? How might they be overcome? Why should we try?The way we frame our questions shapes the way we see solutions. This book does what appears to be a no-brainer task, but one that is missing and important: it asks readers to pose questions in different ways, to shift the vantage point from which they view 'common sense,' and in so doing, to see themselves as part of problems and potential solutions. This is a book about how seeing poverty entails confronting inequality. It is about how acknowledging poverty and inequality leads to uncomfortable revelations about our society and ourselves. And it is about how once we see, we cannot, must not, unsee.This New Edition of This Is What Inequality Looks Like by Teo You Yenn features a new Afterword by the author, and a Foreword by Kwok Kian Woon, Professor of Sociology at the Nanyang Technological University, Singapore.© 2018 by Teo You Yenn. Published in paper format in Singapore by Ethos Books, recorded by Storyside 2019.
