Hey @lengrongfu , Thanks a lot for this! I haven't taken a detailed look, but I had a general question :

You have worked a lot with this part, and implemented several of these mount attr tests. Do you think we can refactor the test logic? What I mean is that is there a common "pattern" in all mount attr tests, that can be extracted in a function and then each individual attr test call this function ; so that individual attr test functions become simpler?

And this is by no means a request to do it in this PR. If that can be done, we might first implement all the tests and then do that in a separate PR. I am just curious to know if that might be possible or not.

Thanks :)

I think it is possible, I create a refactoring issue.
