I have tried many things, but no matter what I do in my tests (which simply sends a PUT request to "create a user") the logs do not enter any of the pathPrefix and just go to the end and fail to match anything.
Can anyone offer insight? Below is the class I have written as well as the simple test (which doesn't even check anything yet)
I know overall it is rather rudimentary and I am not doing things great, but it's just something I threw together to the point where I felt i could do a few quick tests on the routing
