Writing e2e is difficult, what do you think?

@ic4y Can you write unit tests?

I think this is caused by the lack of our CDC-related test cases. Without basic use cases, it is difficult to add use cases for specific scenarios. We need to gradually improve CDC-related test cases. E2E testing is difficult to achieve, but through fine control of the code flow, it should be possible to write use cases for special scenarios.

We can do it later.

Yes, The test cases for CDC are difficult, but we still need to find a way to add e2e, especially as our CDC supports more and more connectors. cc @Carl-Zhou-CN
