Great stuff, just a few initial comments from my first look.

• Would you be able to include tests for the deprecated statemanager methods until they're removed?
• Should the makefile be updated to include a new target that can generate mockfiles using the same flags and which mockgen version/fork you're using e.g. https://github.com/uber-go/mock and a corresponding version

A side note is that I believe we should exclude generated mocks from codecov scans - possibly in a separate PR.

[KentHsu]

Thank you for the feedback. I have updated this PR with

• Added tests for stateManager methods. These tests are duplicates of stateManagerCtx tests.
• Added a new target in Makefile to generate mocks and updated mocks. I'm using golang mock because this is how those mock were generated. mock_factory_impl.go is not created by mockgen so it's not in the Makefile. mock_server.go is updated but I didn't put it in the Makefile because it was manually edited.
• Put mocks in .codecov.yaml ignore. Let me know if this is okay. I'll revert it if it's inappropriate.

Just had another skim-read, looking great so far. I haven't forgotten and will pick the review up tomorrow when I get a moment 👌

[KentHsu]

Sure. Please take your time 👍
BTW, I realize that I do need another PR to update .codecov.yaml... I'll submit another PR to update it when this one is ready.

Is there any reason against using Uber's maintained fork to generate mock interfaces?

[KentHsu]

I tried both and I didn't see anything blocking us from using Uber's fork.
If we want to switch to Uber's fork, I'll have to update go.mod and other test files using these mocks since Uber's fork doesn't work with those original mocks. Is that okay?

[KentHsu]

I went ahead to make some commits to use Uber's gomock fork and revert the change in .codecov.yaml. Please let me know if there's any concern. Thanks.

[KentHsu]

Hi @mikeee, would you like me to create another PR to exclude the mock files so that this PR won't be block by code coverage? Any suggestions on the code change in this PR?

@KentHsu please resolve the conflicts

[KentHsu]

Hi @yaron2, @mikeee , I just resolved the conflicts and updated mocks. Please let me know if there's anything I can do to get this PR merged. Thank you.
