@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());
}
}
パターン:
@ParameterizedTestを使用@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());
}
}
@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());
}
}
@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();
}
}

development
X/Twitter API integration for posting tweets, threads, reading timelines, search, and analytics. Covers OAuth auth patterns, rate limits, and platform-native content posting. Use when the user wants to interact with X programmatically.
documentation
Translate visa application documents (images) to English and create a bilingual PDF with original and translation
tools
See, Understand, Act on video and audio. See- ingest from local files, URLs, RTSP/live feeds, or live record desktop; return realtime context and playable stream links. Understand- extract frames, build visual/semantic/temporal indexes, and search moments with timestamps and auto-clips. Act- transcode and normalize (codec, fps, resolution, aspect ratio), perform timeline edits (subtitles, text/image overlays, branding, audio overlays, dubbing, translation), generate media assets (image, audio, video), and create real time alerts for events from live streams or desktop capture.
development
AI-assisted video editing workflows for cutting, structuring, and augmenting real footage. Covers the full pipeline from raw capture through FFmpeg, Remotion, ElevenLabs, fal.ai, and final polish in Descript or CapCut. Use when the user wants to edit video, cut footage, create vlogs, or build video content.
