Unit testing your API
summary
Shows concrete unit tests for a Java Spring API: service layer for a signPlayer feature, using Mockito to mock player and team repositories and an offToken auth object, asserting calls, arguments and exception paths (player missing, retired, insufficient cap). Demonstrates a working demo service, incremental comment‑out approach, and a beforeEach setup that removes repetitive instantiation; code is ~90% complete and tests run green locally.
