Sporadic java.net.SocketTimeoutException проблема с потребительским тестом пакта junit5

0 голосов
/ 20 сентября 2018

В нашей системе есть два теста пакта junit5.Они работают довольно хорошо, однако время от времени (особенно в конвейере) мы получаем исключение SocketTimeoutException (прилагается ниже)

Код выполняется в экземпляре Docker на основе ubuntu:16.04 и jre: openjdk-8-jdk сбиблиотека пактов au.com.dius:pact-jvm-consumer-junit5_2.12:3.5.22.

Тесты выглядят так: 

@Pact(provider = "http-health-status", consumer = "heartbeat-status-client")
fun `query for a healthy endpoint`(builder: PactDslWithProvider): RequestResponsePact {
    return builder
        .given("a healthy service")
        .uponReceiving("A health api query")
        .matchPath(".*\\/health\$", "/some-service/health")
        .method("GET")
        .willRespondWith()
        .headers(mapOf(HttpHeaders.CONTENT_TYPE to MediaType.APPLICATION_JSON_UTF8_VALUE))
        .body("""{"status":"UP"}""")
        .status(200)
        .toPact()
}


@Test
@PactTestFor(providerName = "http-health-status", pactMethod = "query for a healthy endpoint")
fun `query for a healthy endpoint`(mockServer: MockServer) {
    val httpResponse = subject.query(mockServer.getUrl() + "/some-other-service/health")
   assertThat(httpResponse).isEqualTo(StatusCode.UP)
}

Есть ли какие-либо известные проблемы с нашей настройкой?
