单元测试时无法找到枚举描述符PBFieldDescriptorProto_Label

在将GoogleCast框架添加到单元测试目标后，我在测试开始运行之前收到以下异常。除此之外，SDK功能完整。我会很感激任何想法！单元测试时无法找到枚举描述符PBFieldDescriptorProto_Label

的OCUnit的行为是要经过每一个类，因此调用+initialize:

但这不是由GCKPB_PBGeneratedMessage妥善处理和这个bug已经被报道here。

在等待一个解决方法，临时的解决方案可能是通过将下面的代码来测试类嘲笑GCKPB_PBGeneratedMessage的+initialize方法在单元测试中与OCMock（或任何其它模拟框架）：

#import <OCMock/OCMock.h> 

@interface GCKPB_PBGeneratedMessage : NSObject 
@end

和

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

编辑

作为iOS的发送方API v2.3.0 953，现在已经修复，并且不再需要此解决方法。

哇，伟大的东西！谢谢。 –

这可能是最好的一个新问题，但想到我会先问这里：有没有人有机会想到Kiwi？我试图用KWMock做类似的嘲弄，但它不起作用。 – chaingarden

我在使用Specta进行单元测试时遇到了类似的错误。我通过创建自己的断言处理程序来手动忽略断言。

定义在一个辅助类：

#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
