我的方法的一个参数是**错误,我的项目是在ARC模式.当为此方法编写存根以调用mock方法时,我将参数设置为可能的值.它会导致编译错误或无法匹配参数来调用mock方法.
> OCMOCK_ANY
> [OCMArg anyPointer]
>创建一个NSError对象错误,并表示[OCMArg setTo：error].
没有什么工作.
如何模拟这种方法？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.
解决方法
您可以使用setTo：或anyPointer来转换它：
[[[mockFoo expect] andReturn:nil] someMethodWithError:((NSError __autoreleasing **)[OCMArg anyPointer])];
要么：
NSError *error; [[[mockFoo expect] andReturn:nil] someMethodWithError:((NSError __autoreleasing **)[OCMArg setTo:error])];
这是一个通过您发布的方法传递的测试用例：
@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
