如何在ARC中的OCMock中模拟**参数

Question

我的方法的一个参数是**错误,我的项目处于ARC模式.当为此方法编写存根以调用模拟方法时,我将参数设置为以下可能的值.它导致编译错误或无法匹配参数以调用mock方法.

1. OCMOCK_ANY
2. [OCMArg anyPointer]
3. 创建了一个NSError对象错误,并说[OCMArg setTo:error].

什么都行不通.

如何模仿这种方法？请指教.

-(id)init{

    self = [super init];

    if (self) {
        id wcm = [OCMockObject partialMockForObject:self];
        [[[wcm stub] andCall:@selector(mockGetWakeupCallsForRoomNumber:error:)    onObject:self] getWakeupCallsForRoomNumber:OCMOCK_ANY error:((NSError __autoreleasing **)    [OCMArg anyPointer])];
        //[[[wcm stub] andCall:@selector(testMockMethod) onObject:self] testMethod];

    }
    return self;

}

-(void)testMethod
{
    NSLog(@"Original");
}

-(void)testMockMethod
{
    NSLog(@"Mock");
}
-(NSArray*)mockGetWakeupCallsForRoomNumber:(NSString*)roomNumber error:(NSError**)error
{
    @throw @"Mock method called";
}

-(NSArray*)getWakeupCallsForRoomNumber:(NSString*)roomNumber error:(NSError**)error
{
}

模拟testMockMethod工作.

你可以使用setTo:或者anyPointer如果你施放它:

[[[mockFoo expect] andReturn:nil] someMethodWithError:((NSError __autoreleasing **)[OCMArg anyPointer])];

要么:

NSError *error;
[[[mockFoo expect] andReturn:nil] someMethodWithError:((NSError __autoreleasing **)[OCMArg setTo:error])];

这是一个测试用例,它通过您发布的方法传递:

@interface Foo : NSObject{}

-(NSArray*)mockGetWakeupCallsForRoomNumber:(NSString*)roomNumber error:(NSError**)error;
-(NSArray*)getWakeupCallsForRoomNumber:(NSString*)roomNumber error:(NSError**)error;

@end

@implementation Foo

-(NSArray*)mockGetWakeupCallsForRoomNumber:(NSString*)roomNumber error:(NSError**)error
{
    return @[@"bar"];
}

-(NSArray*)getWakeupCallsForRoomNumber:(NSString*)roomNumber error:(NSError**)error
{
    return nil;
}

@end

@interface SomeTest : SenTestCase {}
@end

@implementation SomeTest

-(void)testMethod
{
    Foo *foo = [Foo new];
    id wcm = [OCMockObject partialMockForObject:foo];
    [[[wcm stub] andCall:@selector(mockGetWakeupCallsForRoomNumber:error:) onObject:foo] getWakeupCallsForRoomNumber:OCMOCK_ANY error:((id __autoreleasing *)[OCMArg anyPointer])];
    NSError *error;
    NSArray *calls = [wcm getWakeupCallsForRoomNumber:@"foo" error:&error];
    STAssertEquals(calls[0], @"bar", @"should match");
}

@end
