단위 테스트의 작성 그리고 완성!

단위 테스트

import static org.assertj.core.api.Assertions.assertThat;

테스트 데이터를 위한 DummyRequestHandler

 

public class DummyRequestHandler {
    @RequestMapping(method = Method.POST, url = "/hello/{id}/{name}")
    public Response bracedURLMethod(long id, Request request, String name) {
        return new Response(200);
    }

    @RequestMapping(method = Method.GET, url = "/hello")
    public Response plainURLMethod(Request request) {
        return new Response(200);
    }

    @RequestMapping(method = Method.GET, url = "/hello/{id}/name")
    public Response hybridURLMethod(int id, Request request) {
        return new Response(200);
    }

    @RequestMapping(method = Method.GET, url = "/hello")
    public Response noArgumentMethod() {
        return new Response(200);
    }
}
