Turns out there's a Kiwi expression to test this I wasn't aware of.
[[editAuthorViewController should] beKindOfClass:[EditAuthorViewController class]];
This failed initially because my EditAuthorViewController.m
file was added to my test target. Since [EditAuthorViewController class
] was returning a different pointer when called from inside the test bundle, the comparison failed.
To fix this, I had to remove EditAuthorViewController.m
from my Compile Sources in my test target.
