我正在尝试测试我的Core Data模型的响应映射。我在Core Data模型中只有几个类，但其中有两个我测试很有趣。第一类是CTFUser类，它保留有关用户的基本信息，第二类是CTFCharacter类。用户可能只有很少的角色（某种类型的玩家）多对多关系。我想要做的是正确编写CTFUser类的测试以及CTFUser和CTFCharacter类之间的关系。当我编写没有属性characters的测试时，NSOrderedSet类型测试已通过。当我尝试在不检查characters value次测试通过的RKPropertyMappingTestExpectation的情况下测试属性{
"username": "tomkowz12",
"email": "tmk.szlc@gmail.com",
"password": "password123",
"nick": "black_lord",
"location": [10, 20],
"characters" : [{
"type": 1,
"total_time": 21,
"total_score": 100,
"health": 100,
"level": 20,
"is_active": 1
},
{
"type": 2,
"total_time": 23,
"total_score": 98,
"health": 55,
"level": 12,
"is_active": 0
}]
}
时。但是当我想检查这个映射的值时，我遇到了崩溃。
测试中使用的JSON夹具：
@interface CTFUser : CustomManagedObject
@property (nonatomic, retain) NSString * email;
@property (nonatomic, retain) NSString * nick;
@property (nonatomic, retain) NSString * username;
@property (nonatomic, retain) NSString * password;
@property (nonatomic, retain) id location;
@property (nonatomic, retain) CTFGame *game;
@property (nonatomic, retain) NSOrderedSet *characters;
+ (NSDictionary *)dictionaryForResponseMapping;
@end
CTFUser类
+ (NSDictionary *)dictionaryForResponseMapping {
return @{@"username" : @"username",
@"email" : @"email",
@"password" : @"password",
@"nick" : @"nick",
@"location" : @"location"};
}
和包含此类的属性映射的字典字典：
@interface CTFCharacter : CustomManagedObject
@property (nonatomic, retain) NSNumber * type;
@property (nonatomic, retain) NSNumber * totalTime;
@property (nonatomic, retain) NSNumber * totalScore;
@property (nonatomic, retain) NSNumber * health;
@property (nonatomic, retain) NSNumber * level;
@property (nonatomic, retain) NSNumber * active;
@property (nonatomic, retain) CTFUser *user;
+ (NSDictionary *)dictionaryResponseMapping;
@end
CTFCharacter class
+ (NSDictionary *)dictionaryResponseMapping {
return @{@"type": @"type",
@"total_time": @"totalTime",
@"total_score": @"totalScore",
@"health": @"health",
@"level": @"level",
@"is_active": @"active"};
}
带有属性映射的字典：
/// Configure mapping
RKEntityMapping *userMapping =
[RKEntityMapping mappingForEntityForName:NSStringFromClass([CTFUser class]) inManagedObjectStore:_manager.managedObjectStore];
[userMapping addAttributeMappingsFromDictionary:[CTFUser dictionaryForResponseMapping]];

}

崩溃日志
characters我犯了错误？应该如何测试- (void)getUser {
CoreDataService *_service = [CoreDataService sharedInstance];
RKManagedObjectStore *managedObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:_service.managedObjectModel];
_connection.manager.managedObjectStore = managedObjectStore;
RKEntityMapping *userMapping =
[RKEntityMapping mappingForEntityForName:NSStringFromClass([CTFUser class]) inManagedObjectStore:managedObjectStore];
[userMapping addAttributeMappingsFromDictionary:[CTFUser dictionaryForResponseMapping]];
RKEntityMapping *characterMapping =
[RKEntityMapping mappingForEntityForName:NSStringFromClass([CTFCharacter class]) inManagedObjectStore:managedObjectStore];
[characterMapping addAttributeMappingsFromDictionary:[CTFCharacter dictionaryResponseMapping]];
[userMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"characters" toKeyPath:@"characters" withMapping:characterMapping]];
RKResponseDescriptor *descriptor = [RKResponseDescriptor responseDescriptorWithMapping:userMapping method:RKRequestMethodGET pathPattern:nil keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[_connection.manager addResponseDescriptor:descriptor];
[_connection.manager getObject:nil path:@"test" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
CTFUser *fetchedUser = (CTFUser *)mappingResult.firstObject;
NSLog(@"%@", fetchedUser);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(@"failure");
}];
}
属性的值？其他值正在测试中并通过。
编辑：
当我发出请求时，来自服务器的响应看起来很好，所有属性和关系都已正确映射，但仍然会出现测试问题。

提前谢谢。
答案 0 :(得分：0)
好的，我做到了。解决方法非常简单。昨天已经晚了所以我没有找到RestKit文档。
而不是使用：
expectationWithSourceKeyPath:destinationKeyPath:value:
我用过：
expectationWithSourceKeyPath:destinationKeyPath:evaluationBlock:
更改后的代码如下所示：
RKPropertyMappingTestExpectation *charactersExpectation =
[RKPropertyMappingTestExpectation expectationWithSourceKeyPath:@"characters" destinationKeyPath:@"characters" evaluationBlock:^BOOL(RKPropertyMappingTestExpectation *expectation, RKPropertyMapping *mapping, id mappedValue, NSError *__autoreleasing *error) {
NSArray *commitedKeysToCompare = @[@"type, totalTime, totalScore, healt, level, active"];
NSArray *array = [mappedValue allObjects];
BOOL containsTwoItems = array.count == 2;
/// Test First character
CTFCharacter *firstFetchedCharacter = (CTFCharacter *)array[0];
CTFCharacter *firstReferenceCharacter = [NSEntityDescription insertNewObjectForEntityForName:NSStringFromClass([CTFCharacter class]) inManagedObjectContext:_service.managedObjectContext];
firstReferenceCharacter.type = @(1);
firstReferenceCharacter.totalTime = @(21);
firstReferenceCharacter.totalScore = @(100);
firstReferenceCharacter.health = @(100);
firstReferenceCharacter.level = @(20);
firstReferenceCharacter.active = @YES;
BOOL isFirstEqual = [[firstFetchedCharacter committedValuesForKeys:commitedKeysToCompare] isEqual:[firstReferenceCharacter committedValuesForKeys:commitedKeysToCompare]];
/// Test Second character
CTFCharacter *secondFetchedCharacter = (CTFCharacter *)array[1];
CTFCharacter *secondReferenceCharacter = [NSEntityDescription insertNewObjectForEntityForName:NSStringFromClass([CTFCharacter class]) inManagedObjectContext:_service.managedObjectContext];
secondReferenceCharacter.type = @(2);
secondReferenceCharacter.totalTime = @(23);
secondReferenceCharacter.totalScore = @(98);
secondReferenceCharacter.health = @(55);
secondReferenceCharacter.level = @(12);
secondReferenceCharacter.active = @NO;
BOOL isSecondEqual = [[secondFetchedCharacter committedValuesForKeys:commitedKeysToCompare] isEqual:[secondReferenceCharacter committedValuesForKeys:commitedKeysToCompare]];
return isFirstEqual && isSecondEqual && containsTwoItems;
}];
