Gatling加料器耗尽了值

Question

我有一个数组，我想用它来做两个供给器。我期望每个feeder都能够使用数组中的所有值。但似乎价值耗尽了

val baseArray = Array (  Map("transactionId" -> "q-1"),
            Map("transactionId" -> "q-2"),
            Map("transactionId" -> "q-3"))


val feeder_getA = baseArray.clone.queue             
val scn_getInsuredOrPrincipals = scenario("getInsuredOrPrincipals")
    .feed(feeder_getA)  
    .exec(http("request_getA").get("/getA/${transactionId}"))

val feeder_getB = baseArray.clone.queue             
val scn_getInsuredOrPrincipals = scenario("getInsuredOrPrincipals")
    .feed(feeder_getB)  
    .exec(http("request_getB").get("/getB/${transactionId}"))   



setUp(
    scn_getInsuredOrPrincipals.inject(
            atOnceUsers(3), // 2
            rampUsers(3) over (5 seconds)
    ),
    scn_getInsuredOrPrincipal.inject(
            atOnceUsers(3), // 2
            rampUsers(3) over (5 seconds)
        )
)   


I get an error saying feeder is now empty after 3 values are consumed... i was assuming feeder_getA  and feeder_getB would each get 3 values so each scenario would get equal number of values. That doesnt seem like  its happening. Almot as if the clone isnt working

问题是，您的feeders是使用queue策略定义的，该策略遍历元素，如果没有更多的元素，则会失败：

val feeder_getA = baseArray.clone.queue

您需要使用circular策略，这可以追溯到最开始：

val feeder_getA = baseArray.clone.circular
