The @Testcontainers and @Container annotations start a MockServerContainer and create a MockServerClient connected to it. @DynamicPropertySource overrides photos.api.base-url to point at the MockServer endpoint, so the application talks to MockServer instead of the real photo service. @BeforeEach resets the MockServerClient before every test so that expectations from one test don't affect another. shouldGetAlbumById() configures a mock response for /albums/{albumId}/photos, sends a request to the application's /api/albums/{albumId} endpoint, and verifies the response body. It also uses mockServerClient.verify() to confirm that the expected API call reached MockServer. shouldReturn404StatusWhenAlbumNotFound() configures MockServer to return a 404 status and verifies the application propagates that status to the caller.\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
