我需要为Swift-PFObject（使用Subclassing）编写一些快速测试，我的课程：
class Category: PFObject, PFSubclassing {
@NSManaged var name : String!
@NSManaged var detail : String!
@NSManaged var iconUrl : String!
@NSManaged var imageUrl: String!
@NSManaged var people : PFRelation!
override class func initialize() {
var onceToken : dispatch_once_t = 0;
dispatch_once(&onceToken) {
self.registerSubclass()
}
}
class func parseClassName() -> String {
return "Category"
}
}
我的测试实施（尚未完成）：
class CategorySpec: QuickSpec {
override func spec() {
var category = Category()
.
.
.
}
}
我已经检查了目标会员资格＆＃39;对于类别类中的测试:(在我的类和方法中不使用公共关键字）。
这是运行测试时的堆栈跟踪：

有什么想法吗？提前谢谢。
