Question

我有一个带POST方法的控制器进行测试。该方法将书籍发布到读者的阅读清单。它将抓取当前经过身份验证的用户作为阅读器。 Book类的字段为Reader类型。以下代码使用contains(samePropertyValuesAs(expectedBook))，但reader实例位置与我明显创建的expectedReader不同。

在MockMVC中测试这种嵌套对象的正确方法是什么？

@Test
@WithUserDetails("z")
public void addBookShouldShowTheBookInReadingList() throws Exception {

    final String bookTitle = "BOOK A";
    final String bookAuthor = "JK";
    final String isbn = "1234567890";
    final String description = "Yet another book.";

    mockMvc.perform(post("/readingList")
            .contentType(MediaType.APPLICATION_FORM_URLENCODED)
            .param("title", bookTitle)
            .param("author", bookAuthor)
            .param("isbn", isbn)
            .param("description", description)
            .with(csrf()))
        .andExpect(status().is3xxRedirection())
        .andExpect(header().string("Location", "/readingList"));


    Reader expectedReader = new Reader();
    expectedReader.setUsername("z");
    expectedReader.setPassword("test");
    expectedReader.setFullName("Z H");

    Book expectedBook = new Book();
    expectedBook.setId(1L);
    expectedBook.setTitle(bookTitle);
    expectedBook.setAuthor(bookAuthor);
    expectedBook.setIsbn(isbn);
    expectedBook.setDescription(description);
    expectedBook.setReader(expectedReader);

    mockMvc.perform(get("/readingList"))
        .andExpect(status().isOk())
        .andExpect(model().attributeExists("books"))
        .andExpect(model().attribute("books", hasSize(1)))
        .andExpect(model().attribute("books", contains(samePropertyValuesAs(expectedBook))));

}

更新 - 其他POST签名。

@Controller
@RequestMapping(value = "/readingList")
public class ReadingListController {

    private ReadingListService readingListService;
    private VersionConfig versionConfig;

    @Autowired
    public ReadingListController(final ReadingListService readingListService,
                                 final VersionConfig versionConfig) {
        this.readingListService = readingListService;
        this.versionConfig = versionConfig;
    }

    @RequestMapping(value = "", method = RequestMethod.GET)
    public String readersBooks(Reader reader, Model model) {
        readingListService.findByReader(reader)
            .ifPresent(books -> {
                model.addAttribute("books", books);
                model.addAttribute("reader", reader);
                model.addAttribute("releaseId", versionConfig.getReleaseId());
            });

        return "readingList";
    }

    @RequestMapping(value = "", method = RequestMethod.POST)
    public String addToReadingList(Reader reader, Book book) {
        book.setReader(reader);
        readingListService.save(book);
        return "redirect:/readingList";
    }
}

因此可以在hamcrast中使用hasToString()匹配器来完成此任务。

mockMvc.perform(get("/readingList"))
        .andExpect(status().isOk())
        .andExpect(model().attributeExists("books"))
        .andExpect(model().attribute("books", hasSize(1)))
        .andExpect(model().attribute("books", contains(hasToString(expectedBook.toString()))));

如何使用Spring MockMVC测试嵌套的Object？
