Spring MVC테스트에서 mocikto와 assertj 로 테스트해보는 연습을 하고 있습니다.

01_테스트대상코드.java

// 밸리데이션이나 이늄 세팅같은 부분은 AOP로 빠졌다. 
@PostMapping("/{boardType}/form")
  public String postCreate(
          @Valid @ModelAttribute BoardArticle article,
          BindingResult result,
          @PathVariable BoardType boardType){
    final BoardArticle save = boardArticleService.save(article);
    log.debug("saved Article : {}", save);
    return article.getBoardType().getRedirectionPage();
  }

02_기존테스트코드.java

public class BoardArticleFormControllerTest extends TestWebConfig {

  @Autowired
  private BoardArticleRepository boardArticleRepository;

  final static private String basicPath="/board/halloffame";

  @Test
  public void writeTest() throws Exception{

    final long count = boardArticleRepository.count();
    final ResultActions perform = mockMvc.perform(
            post(basicPath+"/form")
                    .param("anonymousUserName", "hello")
                    .param("title", "hello title")
                    .param("content", "helloworld")
                    .with(csrf())
            );
    check매처들받아테스트하고_프린트(perform, status().is3xxRedirection());
    assertEquals("카운트 1 증가 ", count + 1, boardArticleRepository.count(), 1L);

    final ResultActions afterPerform = mockMvc.perform(get(basicPath));
    check매처들받아테스트하고_프린트(afterPerform
            , status().isOk()
            , view().name(BoardType.HALLOFFAME.getListPageName())
            , model().attributeExists("boardType")
            , model().attribute("boardType", is(BoardType.HALLOFFAME))
            , model().attributeExists("pageinfo")
            // pageinfo의 content 안에 게시글 컬렉션이 있는데 어떻게 테스트 할지 감이 안 오네요.
            /*,model().attribute("pageinfo",
                    hasProperty("content", hasValue("hello title")))*/
    );
  }
}
