單元測試時無法找到枚舉描述符PBFieldDescriptorProto_Label

在將GoogleCast框架添加到單元測試目標後，我在測試開始運行之前收到以下異常。除此之外，SDK功能完整。我會很感激任何想法！單元測試時無法找到枚舉描述符PBFieldDescriptorProto_Label

的OCUnit的行爲是要經過每一個類，因此調用+initialize:

但這不是由GCKPB_PBGeneratedMessage妥善處理和這個bug已經被報道here。

在等待一個解決方法，臨時的解決方案可能是通過將下面的代碼來測試類嘲笑GCKPB_PBGeneratedMessage的+initialize方法在單元測試中與OCMock（或任何其它模擬框架）：

#import <OCMock/OCMock.h> 

@interface GCKPB_PBGeneratedMessage : NSObject 
@end

和

+ (void)initialize 
{ 
    id mockCastGeneratedMessage = [OCMockObject mockForClass:[GCKPB_PBGeneratedMessage class]]; 
    [[mockCastGeneratedMessage stub] initialize]; 
}

編輯

作爲iOS的發送方API v2.3.0 953，現在已經修復，並且不再需要此解決方法。

哇，偉大的東西！謝謝。 –

這可能是最好的一個新問題，但想到我會先問這裏：有沒有人有機會想到Kiwi？我試圖用KWMock做類似的嘲弄，但它不起作用。 – chaingarden

我在使用Specta進行單元測試時遇到了類似的錯誤。我通過創建自己的斷言處理程序來手動忽略斷言。

定義在一個輔助類：

#define SPT_fail(...) \ 
    SPTSpec *spec = [[SPTCurrentTestCase class] spt_spec];                   \ 
    NSString *message = [NSString stringWithFormat:__VA_ARGS__];                \ 
    [SPTCurrentTestCase recordFailureWithDescription:message inFile:spec.fileName atLine:(int)spec.lineNumber expected:YES];                    \

xxxLoggingAssertionHandler.m：

@implementation xxxLoggingAssertionHandler 

+ (void)load { 
    [xxxLoggingAssertionHandler addHandler]; 
} 

- (void)handleFailureInMethod:(SEL)selector 
         object:(id)object 
         file:(NSString *)fileName 
        lineNumber:(NSInteger)line 
        description:(NSString *)format, ... { 

    // ignore chromecast asserts only 
    NSString *selectorName = NSStringFromSelector(selector); 
    BOOL ignore = [selectorName isEqualToString:@"initWithFieldDescription:rootClass:"] || [selectorName isEqualToString:@"allocDescriptorForClass:rootClass:fields:fieldCount:enums:enumCount:ranges:rangeCount:storageSize:wireFormat:"]; 

    if (!ignore) { 
     SPT_fail(@"NSAssert Failure: Method %@ for object %@ in %@#%i", selectorName, object, fileName, line); 
    } 
} 

- (void)handleFailureInFunction:(NSString *)functionName 
          file:(NSString *)fileName 
        lineNumber:(NSInteger)line 
        description:(NSString *)format, ... { 
    SPT_fail(@"NSCAssert Failure: Function (%@) in %@#%i", functionName, fileName, line); 
} 

+ (void)addHandler { 
    NSAssertionHandler *assertionHandler = [[xxxLoggingAssertionHandler alloc] init]; 
    [[[NSThread currentThread] threadDictionary] setValue:assertionHandler 
                forKey:NSAssertionHandlerKey]; 
} 

+ (void)removeHandler { 
    [[[NSThread currentThread] threadDictionary] setValue:nil 
                forKey:NSAssertionHandlerKey]; 
} 

@end
