Where do I add unit tests? In ServiceManagerTest?

But ServiceManagerTest doesn't run correctly.

This is the result of the original ServiceManagerTest run

You need to verify the split is correct through unit tests

Please do not change the indentation. Maybe you do not use nacos code style. Can you read the style/codeStyle.md in source code directory?

@woxiangwoxiangxiang Please fix code style problem and sign CLA, otherwise we will close this PR.

@woxiangwoxiangxiang Sorry, your CLA still not right, I see the true commit user is wangchunhao not your github id.
So you should use git config user.name and git config user.email to re-commit your change and re-submit a PR to fix it.

BTW, we strongly recommend you use the nacos code style when you change nacos codes.
