@cubxxw can you please help to review, as a CI expert ?

I'm not sure if the make command will work in Github Action (but seems no way to test it unless merge it), can you help me to confirm ?

thank you so much.

Of course, there's no problem with unit tests, and we might need to add a test coverage later on. The Fmt isn't particularly elegant, and the cicd seems to just skip the actions and pass.

Thanks for both of you...
@cubxxw:

1. about the reason why the fmt pass , all files are align with gofmt, so make gofmt returns nothing. Am I right ?
2. Can you help about how to refine the checking for make fmt. you are right, my code looks ugly...

Since there is no change in itself, make fmt may be due to nothing being executed, so there is no corresponding, and you are right.

I will keep this in mind later in the design of the CICD stream. Thank you for trusting me
