Spring Boot Integration test throws error "java.lang.IllegalStateException: Timeout on blocking read for 5000 MILLISECONDS"

Question

The issue happens on my project that uses Spring webflux via Spring boot 2.0.0.M3. Below is the dependencies of project,

dependencies {
        compile 'org.springframework.boot:spring-boot-starter-actuator',
                'org.springframework.cloud:spring-cloud-starter-config',
                'org.springframework.cloud:spring-cloud-sleuth-stream',
                'org.springframework.cloud:spring-cloud-starter-sleuth',
                'org.springframework.cloud:spring-cloud-starter-stream-rabbit',
                'org.springframework.boot:spring-boot-starter-data-mongodb-reactive',
                'org.springframework.boot:spring-boot-starter-data-redis-reactive',
                'org.springframework.boot:spring-boot-starter-integration',
                "org.springframework.integration:spring-integration-amqp",
                "org.springframework.integration:spring-integration-mongodb",
                'org.springframework.retry:spring-retry',
                'org.springframework.boot:spring-boot-starter-webflux',
                "org.springframework.boot:spring-boot-devtools",
                'com.fasterxml.jackson.datatype:jackson-datatype-joda',
                'joda-time:joda-time:2.9.9',
                'org.javamoney:moneta:1.0',
                'com.squareup.okhttp3:okhttp:3.8.1',
                "net.logstash.logback:logstash-logback-encoder:4.11",
                'org.apache.commons:commons-lang3:3.5'
        compileOnly 'org.projectlombok:lombok:1.16.18'
        testCompile 'org.springframework.boot:spring-boot-starter-test',
                'io.projectreactor:reactor-test',
                'org.apache.qpid:qpid-broker:6.1.2',
                'de.flapdoodle.embed:de.flapdoodle.embed.mongo'

        integTestCompile sourceSets.main.output
        integTestCompile configurations.testCompile
        integTestCompile sourceSets.test.output
        integTestRuntime configurations.testRuntime
    }

I have an REST API, and the code is below:

 @RestController
    @RequestMapping(value="/internal/note")
    @Slf4j
    public class NoteController {

        @Autowired
        NoteRepository noteRepository;

        @GetMapping("/request/{id}")
        public Mono<Note> getNoteByRequestid(@PathVariable("id") String requestid) {
            logger.debug("Requesting note by request id '{}'.", requestid);
            return noteRepository.findByRequestid(requestid).doOnSuccess(note ->
                    logger.debug("Found note '{}'.", note))
                    .doOnSuccess(response -> logger.debug("Successfully found note by request id '{}'.", requestid));
        }
    }

The code works fine. When calling the API using Postman, it returns the correct result.

I have the Integration test code like below:

final String data = "{xxxxx}";//JSON Data
    final Note newNote = noteRepository.save(objectMapper.readValue(data, Note.class)).block(Duration.ofSeconds(3));
            final String requestid = "5982C7366FF1C55D20CF2B70";
            this.webClient.get().uri("/internal/note/request/{id}", requestid).accept(MediaType.APPLICATION_JSON_UTF8)
                    .exchange().expectStatus().isOk();

But the test fails throwing error message like below:

 java.lang.IllegalStateException: Timeout on blocking read for 5000 MILLISECONDS

Any advice on how to solve the issue?

i have the same problem and i fix it by overiding the time-out https://stackoverflow.com/a/49496309/4215474 — Mustapha Charboub, Mar 26 '18 at 20:51
I overid the timeout and it work for me check https://stackoverflow.com/a/49496309/4215474 — Mustapha Charboub, Mar 26 '18 at 20:53

This might be a bug in the Framework, but given the amount of stuff you've got on the classpath, you should try to create a minimal, sample project reproducing that and open an issue against Spring Framework (https://jira.spring.io).

The request timeout defaults to 5 seconds. Do your tests take longer than that to run? Maybe while you're actively using your computer simultaneously for other tasks and processes?

If so, when you configure your WebTestClient, set the responseTimeout() to something higher, like so:

@Autowired
private WebTestClient webTestClient;

@BeforeEach
public void setUp() {
    webTestClient =
        webTestClient
            .mutate()
            .responseTimeout(Duration.ofMillis(30000))
            .build();
}

Spring Boot Integration test throws error "java.lang.IllegalStateException: Timeout on blocking read for 5000 MILLISECONDS"
