用參數測試 REST API

[英]Test REST API with parameter

問題描述

我有這個 rest controller ...

@RestController
@RequestMapping(path = "/api")
public class SponsorAPI {
    private SponsorService sponsorService;

    @Autowired
    public SponsorAPI(SponsorService sponsorService) {
        this.sponsorService = sponsorService;
    }

    @GetMapping(path = "/findTopFiveSponsors")
    public ResponseEntity<?> get(@Param("charityId") Long charityId) {
        return ResponseEntity.ok(sponsorService.findTopFiveSponsors(charityId));
    }
}

我想測試一下。 邏輯是，當用戶在慈善頁面上時，他們會在表格中顯示前五名贊助商列表（使用 JPA SQL 查詢以及 Thymeleaf）。

到目前為止我已經寫了這個測試......

@RunWith(SpringRunner.class)
@WebMvcTest(SponsorAPI.class)
public class SponsorAPITest {
    @Autowired
    private MockMvc mockMvc;

    @MockBean
    SponsorService sponsorService;

    @MockBean
    CharityService charityService;

    @Test
    public void shouldReturnTheTopFiveSponsors() throws Exception {
        Sponsor sponsor1 = new Sponsor(2L,
                "Foo Bar",
                charityService.findById(1L).get(),
                "Running a marathon",
                "To help raise funds",
                LocalDateTime.now(),
                LocalDateTime.now(),
                LocalDateTime.now().plusMonths(6),
                "foo-bar");

        Sponsor sponsor2 = new Sponsor(3L,
                "Baz Qux",
                charityService.findById(1L).get(),
                "Participating in a cycling race",
                "To help raise funds",
                LocalDateTime.now(),
                LocalDateTime.now(),
                LocalDateTime.now().plusMonths(6),
                "baz-qux");

        List<Sponsor> sponsors = new ArrayList<>();
        sponsors.add(sponsor1);

        given(sponsorService.findById(2L)).willReturn(Optional.of(sponsor1));

        mockMvc.perform(get("/findTopFiveSponsors").contentType(MediaType.APPLICATION_JSON))
                .andDo(print())
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.fundraiserName", is("Foo Bar")));
    }
}

但我得到這個錯誤......

關於測試這個的替代方法或者上面的代碼是否可以修復的任何建議？ 是我沒有傳遞慈善機構 ID 的問題嗎？ 未找到的價值是為了獲得慈善機構，但我確信該慈善機構存在於數據庫中，因為我已經檢查過它。

編輯：我通過這樣做解決了錯誤......

@Test
    public void shouldReturnTheTopFiveSponsors() throws Exception {
        Charity nspcc = new Charity(1L,
                "12345678",
                "National Society for the Prevention of Cruelty to Children",
                "Kids charity",
                "nspcc",
                "NSPCC",
                true);

        given(charityService.findById(1L)).willReturn(Optional.of(nspcc));

但現在我得到...

java.lang.AssertionError: Status 
Expected :200
Actual   :404

你的方法有錯誤的 url，

       mockMvc.perform(get("/findTopFiveSponsors").contentType(MediaType.APPLICATION_JSON))
                .andDo(print())
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.fundraiserName", is("Foo Bar")));

您的實際 url 是/api/findTopFiveSponsors 。 所以 api 調用應該是

mockMvc.perform(get("/api/findTopFiveSponsors").contentType(MediaType.APPLICATION_JSON))
                .andDo(print())
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.fundraiserName", is("Foo Bar")));
