Waiting a few delay periods before verifying makes the test cover the guard: ```suggestion verify(web3j, after(200).times(1)).replayPastBlocksFlowable(any(), any(), anyBoolean()); ``` ########## components/camel-web3j/src/test/java/org/apache/camel/component/web3j/Web3jConsumerResubscribeTest.java: ########## @@ -0,0 +1,195 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
