I’ve been giving this talk about unit testing UI code lately and of course when you talk about testing, TDD (test driven development) keeps coming up. The question ranges from “have you embraced TDD as the One True Way Of Testing, and if not why not because you’re doing it wrong” and “I have heard that […]
I was talking to a fellow escapee of The Conglomerate and we were talking about over-engineering culture. In the sense of “lol things built because it was time for someone to get promoted” and in the sense of complexity. The thing about layers and layers of (debatably necessary) abstractions is that they make things that should […]
The first iOS project I worked on was a big mess that shipped without unit tests. It was a project that had had a number of different directions taken from a product perspective… and the code was like an archeological record of them. Since then I’ve worked on various things, most of which have been greenfield […]
Submitting I have two ways of submitting to CfPs. The first: a carefully written abstract of a talk that I have already prepped, and probably already given. The second: something that I have already been exploring in blog posts, collected into a “here is this thing that I think I could talk about, but I’m […]
When do we use mocks and when shouldn’t we? Some thoughts: Don’t Mock Data Structures We wouldn’t mock an NSArray or an NSDictionary, so why would we mock our own data structures? Data structures should be simple and well tested, so we can trust them to behave as they should. It will be […]
I was hanging out with an OSS-dude (OSS = Open Source Software) for a while, and I learned a couple of things. Firstly – don’t try and buy committed OSS types books. It’s a complete nightmare. Secondly – I’ve reached a better understanding of harassment and open source. And particularly the pushback, which comes from […]
I want to introduce you to my app, it’s called Show and Hide. It’s an image processing app. This is V1, so the UI is pretty simple, so I think it’s a reasonable example. Briefly, what the app does is it detects the dominant color in an image, and creates these cool partially colored images […]
I’m super excited to release something that I’ve been working on for a while. Unit testing on iOS is… not common. And part of the problem is that people don’t know where to start. It can be overwhelming. Building on my years of experience leading iOS apps with over 80% test coverage, including at Google, […]
My notes from Paul‘s talk at iOSNext. TIOBE Index for Nov 2014 – Swift is at #18. A language that is 5 months old – more popular than Scala, Haskell… Fortran! Proven to be quite a hit with developers, and there are reasons for that. Why do we have a new programming language? What is […]
On my mind this week because I’m giving a workshop and a talk on unit testing UI code on iOS. Tests as Documentation. You think you remember what you did and why… but you don’t. Replace debugging. I almost never use the debugger. If something isn’t working as expected, I just start writing tests and figuring out […]
