About

Me at my computer
Hi, my name is Jon, and I’m test-infected.

Welcome to Quality Coding: “Tools, tips & techniques for building quality into iOS development.” We’ll cover various issues around working quality into our Objective-C code, with an emphasis on unit testing and Test Driven Development (TDD) for iOS.

If you’ve ever wondered if TDD is practical or even possible for iOS apps…
If you wanted to learn TDD but found only trivial examples and no clue of how to approach real-world code…
If you tried TDD for iOS but got stuck without getting very far…
…I’ll help you out. Subscribe below, and I’ll send you the Xcode code snippets I use to speed my own unit testing development.

Testimonials

“Jon is one of those rare engineers who is passionate about the art of programming. You can tell when he waxes poetic about TDD, doing things right, and even by the books on his shelves.”

“Jon generates some of the most readable, maintainable and reusable code that I’ve ever encountered. Many of the idioms and strategies that I learned from Jon are still essential components of my daily coding tasks.”

More about me

I’ve been writing unit tests for over a decade, and have been working as an iOS developer for the past two years. I ported Hamcrest (a library of matchers for building test expressions) to Objective-C (OCHamcrest) as well as to Python (PyHamcrest). Lately, I’ve been working on OCMockito, an Objective-C port of the mocking framework Mockito.

I’ve also been blogging for a decade: Blog One Another shares my spiritual journey between faith and culture, trying to live into the Way of Jesus (without being a jerk).
