Kiwi 是 Objective-C 的单元测试框架，因其简单的接口而著名，基于 Objective-C 编写，只支持 iOS 应用

示例代码：

describe(@"Team", ^{      context(@"when newly created", ^{          it(@"should have a name", ^{              id team = [Team team];              [[team.name should] equal:@"Black Hawks"];          });            it(@"should have 11 players", ^{              id team = [Team team];              [[[team should] have:11] players];          });      });  });
