objc.io is a monthly online magazine, with an editorial team. Each issue focuses on a particular subject, and Issue #15 is about Testing. I’m honored to be a contributor with my article “Dependency Injection”.
Improve your test writing “Flow.”

My article refers to two books I highly recommend:
- Dependency Injection in .NET by Mark Seemann. This book is marvelous, and I need to study it more. (If you’re wondering why an Objective-C programmer is recommending a book with “.NET” in the title, you need to get out more. Learn what’s going on in other languages, and the smart folks who work in them.)
- Working Effectively with Legacy Code by Michael Feathers. This now-classic text was instrumental to me when I first got started writing unit tests, helping me break through many conceptual barriers. Feathers boldly defines legacy code as “code without tests.”
Question: Do you have any comments about my Dependency Injection article, or any of the other Testing issue articles? Leave a comment below.
