Stubbing Methods可以很好地使用'NSUserDefaults',但它似乎不适用于我的自定义方法。
我的测试代码如下:
- (void)testExample
{
id userDefaultMock = OCMClassMock([NSUserDefaults class]);
OCMStub([userDefaultMock standardUserDefaults]).andReturn(userDefaultMock);
OCMStub([userDefaultMock objectForKey:[OCMArg any]]).andReturn(@"user defaults mock obj");
id managerMock = OCMClassMock([ViewManager class]);
OCMStub([managerMock sharedInstance]).andReturn(managerMock);
OCMStub([managerMock generateObjWithObj:[OCMArg any]]).andReturn(@(11));
ViewController *vc = [[ViewController alloc]init];
[vc publicMethod];
}
ViewController中的代码:
- (void)publicMethod
{
[[NSUserDefaults standardUserDefaults]setObject:@"mockObj" forKey:@"mockObjKey"];
id obj = [[NSUserDefaults standardUserDefaults]objectForKey:@"mockObjKey"];
NSLog(@"mockObjKey:%@",obj);
NSNumber *num = @(0);
NSNumber *i = [[ViewManager sharedInstance] generateIndexWithNumber:num];
NSLog(@"i expected to be 1, actual :%ld",i.integerValue);
}
ViewManager中的代码:
static ViewManager *sharedViewManager = nil;
+ (id)sharedInstance
{
if (nil == sharedViewManager)
{
sharedViewManager = [[ViewManager alloc]init];
}
return sharedViewManager;
}
- (NSNumber *)generateIndexWithNumber:(NSNumber *)index
{
NSLog(@"generateIndexWithNumber:%ld",index.integerValue);
return @(index.integerValue + 1);
}
和控制台输出如下:
2017-07-03 10:12:25.812 OC_Unit[2214:64454] mockObjKey:user defaults mock obj
2017-07-03 10:12:25.812 OC_Unit[2214:64454] generateIndexWithNumber:0
2017-07-03 10:12:25.812 OC_Unit[2214:64454] i expected to be 1, actual :1
如果shubbing方法有效,最后一行输出应该是'我希望是1,实际:11'。我想知道,为什么它没有按预期输出。
答案 0 :(得分:1)
看起来你正在追踪generateObjWithObj:
,但代码正在调用generateIndexWithNumber:
。
