实际代码

#import "MTLTestModel.h"

SpecBegin(MTLModel)

describe(@"subclass", ^{
    it(@"should not include dynamic readonly properties in +propertyKeys", ^{
        NSSet *expectedKeys = [NSSet setWithObjects:@"name", @"count", @"nestedName", nil];
        expect(MTLTestModel.propertyKeys).to.equal(expectedKeys);
    });
});
