MAVEN PROJECT User Registration and login Application Spring Boot

Currently I have an API with methods(UserController.java) that interact with the database MongoAtlas(UserRepository.java) that get called by the UI. The methods that I have in UserController are the working methods for my application. What I want to do now is create JUnit testing for each of the methods. I have sent screenshots of the methods in UserController.java and my UserControllerTest.java. My Junit test cases that I have written are failing. Could someone fix or rewrite my test cases so they work. thank you!
