Social + Tool Driven Quality Control

The follow-up I wrote for CocoaPods issue #1852 covers a lot of technical ground, but I also wanted to tackle the issue from a less crash reporting-focused perspective.

While I think the technical direction is interesting, and we're exploring some of these ideas in PLCrashReporter, it's easy to lose sight of the original goal -- ensuring that CocoaPod users can introduce library dependencies without concern that there are significant regressions in a given library or release.

In this area, I think that social and tool-driven hints are not only cheaper to implement, but would be just as powerful -- if not more so -- than a complex crash reporting system that can only find issues after they've already shipped.

If you look at automated build and dependency tooling on other platforms (in particular, I have Maven since that's what I'm familiar with, but these notions are hardly unique to the JVM language family),

Getting a Mocta object

NSUserDefaults<Mocta> *defaults = [Mocta objectWithClass:[NSUserDefaults class]];
id< UITableViewDelegate, MoctaStub> delegate = [Mocta objectWithProtocol:@protocol(UITableViewDelegate)];

Expectations

Expectations are ran on dealloc, or at the end of the test case, so I don't have to do it manually.

• Create bootable installer image with https://ntk.me/2012/09/07/os-x-on-os-x/:
  • $ [sudo] gem install iesd
  • $ iesd -i '/path/to/Install OS X Yosemite.app’ -o /path/to/boot-image.dmg
  • If low on disk space, be sure to prepend: $ env TMPDIR=/path/to/disk/with/space/tmp iesd …
• Install VM:
  • Place HD image inside dir with other VM files
  • Format HD with name of OS, e.g. Yosemite
• Reduce used disk space with http://apple.stackexchange.com/a/48922:
  • Remove localisation files with Monolingual

• Remove /System/Library/Speech/Voices/*
