Testing Web Controllers with MockMvc
Write focused tests for your REST endpoints using MockMvc to simulate HTTP requests without starting a real server.
Why Test Controllers in Isolation?
Controller tests verify routing, request mapping, status codes, and JSON serialization without the cost of a full server. MockMvc makes this fast and precise.
