Unit Testing: Stop Shipping Garbage
How to End the Cycle of Rework, Delays, and Technical Debt
By Jonathan Jenkins
Why this book matters?
Simple, address the problems at the source or go out of business
Your organization is in a race to do more, faster, and safer than ever before. This is the playbook for winning that race. It provides a brutally practical, no-nonsense guide for leaders—both technical and non-technical—to end the cycle of rework, delays, and technical debt that secretly sabotages your ability to innovate. Stop shipping garbage and start building software that gives you a competitive edge.
This isn’t just about code; it’s about culture and economics. You will learn how to build a high-performance engineering culture that moves with speed and confidence, because quality is built in, not bolted on. This book gives you the framework to have the tough, necessary conversations that transform your development process from a cost center into a strategic asset, allowing you to go faster because you are building on a foundation of rock-solid quality.
In the age of AI, the stakes are higher than ever. When your products rely on third-party AI APIs, your code is the only thing standing between a powerful tool and a catastrophic failure. This book is an absolute must for any organization integrating AI, providing the essential strategies to build the resilient, testable, and reliable software required to control these powerful, unpredictable systems. Without this discipline, you are not innovating with AI; you are gambling with it.
Get the executive playbook for driving a culture of quality and accountability
Quality is not a technical detail; it is a leadership issue. As a leader, you don’t need to write the code, but you are responsible for the culture that produces it.
This book provides the executive playbook for driving a culture of quality and accountability. It arms you with the probing questions to ask your technical leadership to determine if your teams are truly committed to quality or just performing a ceremony. This is your guide to having the tough conversations that will ultimately save your projects.
Understand the brutal financial cost of skipping tests and the economic case for quality
Skipping unit tests isn’t saving time; it’s a high-interest loan from the future, and the bill always comes due. My book lays out the brutal economic case for automated testing, grounded in hard industry data.
Discover why a bug that costs $1 to fix during development can cost over $100 to fix in production, and how elite teams leverage automated testing to deploy code hundreds of times more frequently with significantly lower failure rates. This is the business case for quality that every leader needs to understand.
Learn to control unpredictable AI APIs by rigorously testing the code that surrounds them
AI APIs, whether built in-house or from a vendor, are powerful but unpredictable. Their non-deterministic nature means you can’t test the AI itself, but you MUST rigorously test the code that surrounds it. This reading provides the essential playbook for this new reality.
You will learn how to isolate the AI by mocking its responses, allowing you to unit test your own code’s logic for data preparation, error handling, and response processing. This is how you build a reliable system around an unpredictable component, ensuring that you are controlling the AI, not gambling with it.
