With `deleteAfterRead=true` the object is deleted when the exchange completes, which is after it reached `mock:result`, so `assertIsSatisfied()` can return before `c.txt` is deleted. Waiting for the bucket closes the race: ```suggestion await().atMost(20, TimeUnit.SECONDS).untilAsserted( () -> assertEquals(Set.of("b.txt"), Set.copyOf(objects), "a.txt and c.txt are consumed and deleted, b.txt stays")); ``` ########## components/camel-huawei/camel-huaweicloud-obs/src/test/java/org/apache/camel/component/huaweicloud/obs/OBSConsumerObjectThatCannotBeGotTest.java: ########## @@ -0,0 +1,217 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
