Mockito cannot mock this class : Mockito can only mock non-private & non-final classes
Mockito cannot mock this class : Mockito can only mock non-private & non-final classes
对于一次大学考试,我被要求测试一些 apache 簿记员 classes/methods 并且在这样做时我想在我的参数化测试中使用 mockito。
没有 mockito 的测试工作正常但是当我尝试模拟接口时我得到这个错误:
org.mockito.exceptions.base.MockitoException:
Mockito cannot mock this class: interface org.apache.bookkeeper.discover.RegistrationManager.
Mockito can only mock non-private & non-final classes.
If you're not sure why you're getting this error, please report to the mailing list.

2条笔记:
- 我也发布了我的测试 class 代码以确保在使用参数化测试和 mockito 时没有冲突
- 据我所知,问题出在 byteBuddy 而不是 mockito 本身,但我不知道如何解决这个问题。
我使用的 Mockito 版本是 3.0.0
字节好友版本为1.9.3
希望你能帮帮我,
祝大家有个美好的一天:P
查看this bug report,您可能遇到了与 ByteBuddy 和 Mockito 版本不兼容的问题。
尝试将 Mockito 降级到 2.23 版或将 ByteBuddy 升级到 1.97 版。
