Proposal: Adding e2e testing for this project

[LinuxSuRen]

As mentioned in the title, I'd like to add the e2e testing for this project. Basically, the flow is like the below:

• Start the server with docker-compose
• Run API testing

This is another PR for which I submit an e2e testing.

I'm looking forward to see comments about this.

@LinuxSuRen Thanks. We have considered adding more test suites here. If you'd like to contribute to the e2e testing, please feel free to open a PR for this.
