IOS单元测试工具之OCMockito
这里给大家介绍一个新的开源工具OCMockito 下载地址, 我这里通过CocoaPods，导入到我的测试项目中，
#import 下面是我测试是遇到的第一个问题，给大家来分享下：
//创建mock对象
NSMutableArray *mockArray = mock([NSMutableArray class]);
//使用mock对象
[mockArray addObject:@”one”];
[mockArray removeAllObjects];
//对相关的行为进行验证
[verify(mockArray) addObject:@"one"];
[verify(mockArray) removeAllObjects];
但是却爆出这样的错误
这个主要是在编译器设置一下就好了，我用的编译器是Xcode7.2.1，我的设置如下：
下面来看看运行效果吧，我们发现运行正常，什么都没有提示，下面我把数据改一下看看
[verify(mockArray) addObject:@"two"];
[verify(mockArray) removeAllObjects];运行结果如下：

(lldb) 上面把原因说的很清楚咯，嘿嘿，后面我们就可以进行愉快的学习啦。另外说明一下哦，书上的代码还用到了OCHamcrest里面的测试函数，所以要引入这个头文件
#import 下面是书上的一些简单的测试代码，下面和大家分享下，大家可以试试哦
NSMutableArray *mockArray = mock([NSMutableArray class]);
//使用mock对象
[mockArray addObject:@"one"];
[mockArray removeAllObjects];
//对相关的行为进行验证
[verify(mockArray) addObject:@"two"];
[verify(mockArray) removeAllObjects];
stubing 相关的内容
//建立mock对象
NSArray *mockArray1 = mock([NSArray class]);
//stubing
[given([mockArray1 objectAtIndex:0]) willReturn:@"first"];
//打印得到钢材的stubing
NSLog(@"%@",[mockArray1 objectAtIndex:0]);
//参数的验证
建立mock对象
NSMutableArray *mockArray2 = mock([NSMutableArray class]);
//使用mock对象
[mockArray2 removeObject:@"This is a test!"];
//对相关的参数进行验证
[verify(mockArray2) removeObject:startsWith(@"This is")];
//验证调用关系及被调用到的次数
//创建mock对象
NSMutableArray *mockArray3 = mock([NSMutableArray class]);
//使用mock对象
[mockArray3 addObject:@"once"];
[mockArray3 addObject:@"twice"];
[mockArray3 addObject:@"twice"];
[verify(mockArray3) addObject:@"once"]; //addObject:@"once" 被调用过
[verifyCount(mockArray3, times(1)) addObject:@"once"]; //addObject:@"once"被调用过一次
[verifyCount(mockArray3,times(2)) addObject:@"twice"]; //addObject:@"twice"被调用过2次
[verifyCount(mockArray3, times(3)) addObject:@"twice"]; //addObject:@"twice"被调用过3次
[verifyCount(mockArray3, never()) addObject:@"never happened"]; //addObject:@"never happened"从来没有被调用过
[verifyCount(mockArray3, atLeastOnce()) addObject:@"at least once"]; //addObject:@"at least once"是在最后被调用的
这里面的代码我都测试过了，大家如果有遇到什么问题可以和我沟通哦
