Hi, I’m Jon Reid. I’ve been practicing Test Driven Development (TDD) since 2001, and applying it to Objective-C since 2005. I’m the author of OCHamcrest and OCMockito.

My Speaking Appearances

I’ve spoken at the following conferences and meetups:

  • Mobile Central Europe 2014 and MCE^3 2016
  • eBay Tech Talk Berlin
  • CocoaConf San Jose
  • iOSDev UK
  • NSSpain
  • CocoaPods Test Jam

My Content

My mission is to help iOS developers create code that is maintainable. Any coder can hack out programs that “work” at first. But will you be able to easily modify it over many years, or across multiple projects?

That’s why I write on TDD, unit testing, architecture & design, project structure & language, and tools. You can find out more on my Start Here page.

My goal is to equip you with practical approaches that you can put to work. If you’ve ever been frustrated by fragile code, or interested in unit testing but afraid it would slow you down — then this blog is especially for you.

I try to post once a week. To make sure you don’t miss my newest posts, you can subscribe via email. It’s quick, easy, and you can unsubscribe at any time.

My Biography

I became interested in programming during junior high school, at the American School In Japan. But I really caught the bug during my 9th grade year, when I lived next to Earlham College. I entered programs from BASIC Computer Games on their PDP-11/70.

Back at the American School In Japan, the computers upgraded from FORTRAN punch cards sent to some mainframe in downtown Tokyo, to Radio Shack TRS-80’s. My friends and I started writing programs in earnest, such as different implementations of Conway’s Game of Life.

I studied computer science at Purdue University. While back in Japan, I met my wife-to-be who, like me, was a missionary kid. We married and went to Japan for three years as Christian missionaries ourselves. I worked in the computer science department of Tohoku Gakuin University in Sendai, where I extended Knuth’s “literate programming” system to handle Japanese text.

I became interested in various ideas that promised to make programming better, such as code generation and verification. But what really caught my attention was something new called object-oriented programming. Back to school I went, this time for a master’s at UIUC. I learned Smalltalk.

My wife & I started raising children and moved to Silicon Valley, where I’ve worked for various companies. A wonderful book about object-oriented design came out called Design Patterns. Hungry for more, I searched the web and found the very first wiki, c2.com. It was filled with discussions about design patterns, discussion of different styles of wiki use, and another new thing called Extreme Programming. I learned about the Extreme practices, including “test-first programming” — later renamed Test Driven Development.

I began teaching on best practices at my work, wherever that happened to be. I wanted to share with more people, so I started this blog. Speaking engagements followed. I am now available for on-site training and consulting / code reviews.
