Spring WebFlux Test – Timeout on blocking read for 5000 MILLISECONDS
Test a Spring Webflux endpoint with the WebTestClient, and hits the following error messages. Is this possible to increase the timeout?
java.lang.IllegalStateException: Timeout on blocking read for 5000 MILLISECONDS

Solution
By default, the WebTestClient will be timeout after 5 seconds. We can configure the timeout with @AutoConfigureWebTestClient
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureWebTestClient(timeout = "10000")//10 seconds
public class TestCommentWebApplication {
@Autowired
private WebTestClient webClient;

Unfortunately, it still failed. IT prints the timeout as 5 sec even though changed to 10 sec

@AutoConfigureWebTestClient(timeout = “10000”)
While build web test client you can give response timeout.
WebTestClient.bindToServer()
.responseTimeout(Duration.ofMillis(10000L))
.baseUrl(String.format(“http://localhost:%s”, yourPort))
.build();
