objective-c - OCMock - 试图模拟 NSEntityDescription

Question

为了测试托管类，我尝试通过首先尝试模拟 NSEntityDescription 和 NSManagedObjectContext 在单元测试中创建一个实例。

id mockEntityDesc = [OCMockObject niceMockForClass:[NSEntityDescription class]];
id mockManagedObjectContext = [OCMockObject mockForClass:NSManagedObjectContext.class];

但是在我进一步了解之前，我在运行测试时收到以下错误；

Undefined symbols for architecture i386: "_OBJC_CLASS_$_NSEntityDescription", referenced from: objc-class-ref in CallsCoordinatorTests.o "_OBJC_CLASS_$_NSManagedObjectContext", referenced from: objc-class-ref in CallsCoordinatorTests.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

有什么建议吗？谢谢
