Junit으로 Controller를 테스트 하는 과정에서 =AbstractMethodError가 납니다.

Question

안녕하세요.최근들어 spring framework을 공부중인 학생입니다.프로그램을 짠 뒤에 테스트 코드를 만들어 보고 싶어서 만드는 도중 에러가 나서 며칠째 진행하지 못하는 상황에 처해 버렸습니다. 로그도 보고 구글링도 해봤지만, 도대체 무엇 때문에 테스트가 진행되지 않는지 좀처럼 갈피를 잡을 수 없어서 질문을 드리게 되었습니다. 번거로우시겠지만, 한번만 봐주시면 감사하겠습니다.junit의 failure trace는 아래와 같습니다.org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.AbstractMethodError: org.springframework.mock.web.MockHttpServletResponse.getHeaders(Ljava/lang/String;)Ljava/util/Collection; at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:978) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:897) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:970) at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:861) at javax.servlet.http.HttpServlet.service(HttpServlet.java:634) at org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:846) at org.springframework.test.web.servlet.TestDispatcherServlet.service(TestDispatcherServlet.java:66) at javax.servlet.http.HttpServlet.service(HttpServlet.java:741) at org.springframework.mock.web.MockFilterChain$ServletFilterProxy.doFilter(MockFilterChain.java:168) at org.springframework.mock.web.MockFilterChain.doFilter(MockFilterChain.java:136) at org.springframework.test.web.servlet.MockMvc.perform(MockMvc.java:134) at kr.or.papercraft.reservation.controller.api.CategoryContollerTest.list(CategoryContollerTest.java:43) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:74) at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:83) at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:72) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:231) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:88) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:71) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:174) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:89) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:41) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:542) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:770) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:464) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:210)Caused by: java.lang.AbstractMethodError: org.springframework.mock.web.MockHttpServletResponse.getHeaders(Ljava/lang/String;)Ljava/util/Collection;

Junit으로 Controller를 테스트 하는 과정에서 =AbstractMethodError가 납니다.
