A Fresh Look at Testing
There are as many opinions about testing as there are developers, and then some. The opinions run the range from considering all testing a waste of time, to the belief that only unit testing is worthwhile, to an insistence that end to end tests are the most important, to a dismissal of end-to-end tests as not maintainable.

Blog Update: Back to Life and Finally Adding SSL
And CloudFlare made it really easy!
So, my blog has gone somewhat neglected for a couple years now and I’m sort of blown away by how fast that time went by... Being busy at work, busy with small kids and busy with side projects all meant that my little corner of the Internet dried up like an abandoned lawn in Arizona.
And part of that sad neglect included never adding . . .
WWDC 2017 Wishlist
It's the night before WWDC and so while this post is pretty late, its technically not too late to be appropriate. But not having much time to type this up means that I'm not able to go into as much detail as I normally do for these wishes and they are all going into a single post.
Some interesting context going into WWDC . . .
A Single Writer Pattern in Swift
A Fun Experiment With Shared Mutable State and Lock-Free "Locking"
I was talking to a co-worker today about different ways to minimize the risks around having a single shared instance in any app that holds global values which can be read and written to from anywhere in the code.
The potential risks around global mutable state are discussed in lots of places, but some of the key problems are:. . .
Towards Better Unit Testing
Last year, I wrote a post about the problems with code coverage as a metric, and left the topic as “to be continued”, saying that I had some ideas for a better approach. Well, it's taken long enough, but here are the first pieces in that objective to evolve a better way to create and measure well-tested software.
What Makes Good . . .
Swift-y Dependency Injection, Part Two
Injecting unique, mutable and persistent property values
Update: The original approach and sample code in this post have been modified slightly — instead of every Injected instance defining its own storage for injected traits, the Injectable struct instead defines global storage for all Injected instances. This is to allow let / constant struct instances to be injected with a stored trait without . . .
A Swift-y Approach to Dependency Injection
While I would guess that fewer iOS developers are concerned with Dependency Injection than say, Java developers, the concept has gained more steam on the platform as the practice of unit and integration testing has increased.
In short, Dependency Injection (or DI) consists of:
Making your structs or classes depend on . . .
