我正在使用 CoreBluetooth，所以在我的单元测试中，我正在模拟所有 CB 对象，以便它们返回我想要的。在我的一个测试中，我模拟了一个 CBPeripheral，并像这样存根委托方法：

[[[mockPeripheral stub] andReturn:device] delegate];

传入的设备是我的包装对象，它保留在外围设备上。稍后在测试中，我在设备上调用一个方法，然后检查：

NSAssert(_peripheral.delegate == self, @"Empty device");

由于_peripheral.delegate != self，此行在测试期间被断言。

我已经调试过了，并确保_peripheral是一个 OCMockObject。当断言检查_peripheral的委托时，为什么存根方法不返回设备？

下面是详细代码：

@interface Manager : NSObject
- (void)connectToDevice:(Device*)device;
@end

@implementation Foo

- (void)connectToDevice:(Device*)device {
    if([device checkDevice]) {
        /** Do Stuff */
    }
}

@end

@interface Device : NSObject {
    CBPeripheral _peripheral;
}
- (id)initWithPeripheral:(CBPeripheral*)peripheral;
@end

@implementation Device

- (id)initWithPeripheral:(CBPeripheral*)peripheral {
    self = [super init];
    if(self) {        
        _peripheral = peripheral;
        _peripheral.delegate = self;
    }
    return self;
}

- (BOOL)checkDevice {
    NSAssert(_peripheral.delegate == self, @"Empty device");
    return YES;
}

@end

@implementation Test

__block id peripheralMock;

beforeAll(^{
    peripheralMock = [OCMockObject mockForClass:[CBPeripheral class]];
});

//TEST METHOD
it(@"should connect", ^{
    Device *device = [[Device alloc] initWithPeripheral:peripheralMock];

    [[[peripheralMock stub] andReturn:device] delegate];

    [manager connectToDevice:device];
}
@end

我无法重现这个 - 这是你在做什么？

@interface Bar : NSObject <CBPeripheralDelegate>
@property (nonatomic, strong) CBPeripheral *peripheral;
- (void)peripheralTest;
@end

- (void)peripheralTest
{
    NSAssert(_peripheral.delegate == self, @"Empty device");
}

// In test class:    
- (void)testPeripheral
{
    Bar *bar = [Bar new];
    id peripheralMock = [OCMockObject mockForClass:CBPeripheral.class];
    [[[peripheralMock stub] andReturn:bar] delegate];
    bar.peripheral = peripheralMock;
    [bar peripheralTest];
}

这个测试对我来说通过了。
