@mingxin0607 thank you for starting the unit test effort, we need this! Is there any other tests cases you were thinking to add? We separated out most functions to packages/server/src/utils, they should be good for unit tests

Thank you for your information! I just added a test case for logger.ts under packages/server/src/utils, and made a new pull request.
