Spring Boot TDD Workflow

Execute test-driven development for Spring Boot services using JUnit 5, Mockito, and JaCoCo with 80%+ coverage.

Spring Boot TDD İş Akışı

80%+ kapsam (unit + integration) ile Spring Boot servisleri için TDD rehberi.

Ne Zaman Kullanılır

  • Yeni özellikler veya endpoint'ler
  • Bug düzeltmeleri veya refactoring'ler
  • Veri erişim mantığı veya güvenlik kuralları ekleme

İş Akışı

  1. Önce testleri yazın (başarısız olmalılar)
  2. Geçmek için minimal kod uygulayın
  3. Testleri yeşil tutarken refactor edin
  4. Kapsamı zorlayın (JaCoCo)

Unit Testler (JUnit 5 + Mockito)

@ExtendWith(MockitoExtension.class)
class MarketServiceTest {
  @Mock MarketRepository repo;
  @InjectMocks MarketService service;

  @Test
  void createsMarket() {
    CreateMarketRequest req = new CreateMarketRequest("name", "desc", Instant.now(), List.of("cat"));
    when(repo.save(any())).thenAnswer(inv -> inv.getArgument(0));

    Market result = service.create(req);

    assertThat(result.name()).isEqualTo("name");
    verify(repo).save(any());
  }
}

Desenler:

  • Arrange-Act-Assert
  • Kısmi mock'lardan kaçının; açık stubbing tercih edin
  • Varyantlar için @ParameterizedTest kullanın

Web Katmanı Testleri (MockMvc)

@WebMvcTest(MarketController.class)
class MarketControllerTest {
  @Autowired MockMvc mockMvc;
  @MockBean MarketService marketService;

  @Test
  void returnsMarkets() throws Exception {
    when(marketService.list(any())).thenReturn(Page.empty());

    mockMvc.perform(get("/api/markets"))
        .andExpect(status().isOk())
        .andExpect(jsonPath("$.content").isArray());
  }
}

Entegrasyon Testleri (SpringBootTest)

@SpringBootTest
@AutoConfigureMockMvc
@ActiveProfiles("test")
class MarketIntegrationTest {
  @Autowired MockMvc mockMvc;

  @Test
  void createsMarket() throws Exception {
    mockMvc.perform(post("/api/markets")
        .contentType(MediaType.APPLICATION_JSON)
        .content("""
          {"name":"Test","description":"Desc","endDate":"2030-01-01T00:00:00Z","categories":["general"]}
        """))
      .andExpect(status().isCreated());
  }
}

Persistence Testleri (DataJpaTest)

@DataJpaTest
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
@Import(TestContainersConfig.class)
class MarketRepositoryTest {
  @Autowired MarketRepository repo;

  @Test
  void savesAndFinds() {
    MarketEntity entity = new MarketEntity();
    entity.setName("Test");
    repo.save(entity);

    Optional<MarketEntity> found = repo.findByName("Test");
    assertThat(found).isPresent();
  }
}

Testcontainers

  • Production'ı yansıtmak için Postgres/Redis için yeniden kullanılabilir container'lar kullanın
  • JDBC URL'lerini Spring context'e enjekte etmek için @DynamicPropertySource ile bağlayın

Kapsam (JaCoCo)

Maven snippet:

<plugin>
  <groupId>org.jacoco</groupId>
  <artifactId>jacoco-maven-plugin</artifactId>
  <version>0.8.14</version>
  <executions>
    <execution>
      <goals><goal>prepare-agent</goal></goals>
    </execution>
    <execution>
      <id>report</id>
      <phase>verify</phase>
      <goals><goal>report</goal></goals>
    </execution>
  </executions>
</plugin>

Assertion'lar

  • Okunabilirlik için AssertJ'yi (assertThat) tercih edin
  • JSON yanıtları için jsonPath kullanın
  • Exception'lar için: assertThatThrownBy(...)

Test Veri Builder'ları

class MarketBuilder {
  private String name = "Test";
  MarketBuilder withName(String name) { this.name = name; return this; }
  Market build() { return new Market(null, name, MarketStatus.ACTIVE); }
}

CI Komutları

  • Maven: mvn -T 4 test veya mvn verify
  • Gradle: ./gradlew test jacocoTestReport

Unutmayın: Testleri hızlı, izole ve deterministik tutun. Uygulama detaylarını değil, davranışı test edin.
