Where should I change the root URL when I want to run REopt in local development mode using CBC?

[a3678911]

I have rebuilt and run REopt docker images in local development mode using CBC, and the image starts well.
But the question is that none of tests under reo/tests can be passed, so should I change somewhere else to cater to the shift from web mode to local mode?
As https://github.com/NREL/reopt_api/wiki/Using-docker-for-local-development says, I must make POST's and GET's root URL as 0.0.0.0:8000/v1/ , where should I change the codes? Is the testing python codes or something else(maybe a profile)?
