Hello, I’m Karen Johnson
I’ve returned to the world of software testing — and to writing. I’m honored to have contributed a chapter to Taking Testing Seriously, an upcoming book to be published by Wiley Press. More details about the book and my chapter can be found below.
Background
My professional journey in software spans a wide range of roles and experiences. I began my career as a technical writer — a fitting start for someone naturally quiet and observant. From there, I discovered a passion for finding defects and advocating for better software quality, which led me through the classic progression from tester to test lead, test manager, and eventually consultant.
For nine years, I worked as an independent consultant, choosing projects that challenged and inspired me. Later, I returned to corporate leadership roles, serving as Director of Quality and Director of Engineering. During the pandemic, I experienced a layoff and chose to take a sabbatical break to reset and reshape my professional path.
Speaking and Mentorship
Over the years, I also stepped into the world of public speaking — something that once felt far outside my comfort zone. With the encouragement and coaching of my colleague, James Bach, I transitioned from reluctant speaker to keynote presenter and tutorial instructor at industry conferences. His mentorship was instrumental, and his recent invitation to contribute to his latest book played a meaningful part in my return to the testing community.
Today
I’ve come back to where it all began — hands on keyboard, exploring, testing, and uncovering insights that make software stronger. Right now, I’m focused on the craft itself: thoughtful, hands-on testing.
In time, I expect to share more through writing and speaking again. For now, I’m right where I want to be — back in the work I love.
New Publication
I recently had the honor of contributing a chapter to Taking Testing Seriously, an upcoming book from Wiley Press. My chapter explores a theme that’s central to my work — the importance of continual learning in an ever-changing field.
In our constantly evolving field, learning isn’t just valuable — it’s vital. I often say that if someone needs to feel like a master of their domain, technology might not be the right place for them. What we know today matters, but by next year, we’re often working with entirely new tools, frameworks, and ideas.
When I wrote my chapter, I was still on sabbatical — unaware that this theme of learning would soon shape my own return to the field. Now, I’m living what I wrote: the joy of discovery and the challenge of applying new knowledge in real time.
The book, Taking Testing Seriously, is a major project led by James Bach and Michael Bolton. Together, they’ve created a comprehensive exploration of software testing that brings together a dozen authors, each offering unique insights and perspectives on the craft. It’s both a celebration of experience and an invitation to keep learning.
Past Publication
Beautiful Testing — published by O’Reilly Media — is part of the Beautiful series of books highlighting thoughtful perspectives on software craftsmanship. My contribution, a chapter titled “Software in Use,” draws from my experience testing medical software — and from a deeply personal moment when a family member depended on similar software during a critical illness.
That experience reshaped how I think about quality, reliability, and the human side of technology.
