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 功能齐全。我将不胜感激任何想法!

解决方案
OCUnit 的行为是遍历每个类,然后调用 +initialize:
但这没有得到正确处理 GCKPB_PBGeneratedMessage
并且这个错误已经被报告了 这里.
在等待修复时,临时解决方案可能是模拟 GCKPB_PBGeneratedMessage
的 +initialize
通过将以下代码添加到测试类中,使用 OCMock(或任何其他模拟框架)在单元测试中使用方法:
#import <OCMock/OCMock.h>
@interface GCKPB_PBGeneratedMessage : NSObject
@end
和
+ (void)initialize
{
id mockCastGeneratedMessage = [OCMockObject mockForClass:[GCKPB_PBGeneratedMessage class]];
[[mockCastGeneratedMessage stub] initialize];
}
编辑
从 iOS 发送器 API v2.3.0 953 开始,此问题现已修复,不再需要此解决方法。
其他提示
使用Specta进行单位测试时,我遇到了类似的错误。通过创建自己的断言处理程序,我手动忽略了断言。
在辅助课程中定义:
#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
