    await sleepAsync(100.milliseconds)
    await destNode.connectToNodes(@[bridgeNode.peerInfo.toRemotePeerInfo()])

    ## Given
    let message = fakeWakuMessage()

    var completionFutRelay = newFuture[bool]()
    proc relayHandler(topic: PubsubTopic, msg: WakuMessage): Future[void] {.async, gcsafe.} =
      check:
        topic == DefaultPubsubTopic
        msg == message
      completionFutRelay.complete(true)
    destNode.subscribe(DefaultPubsubTopic, relayHandler)

    # Wait for subscription to take effect
    await sleepAsync(100.millis)

    ## When
    await lightNode.lightpushPublish(some(DefaultPubsubTopic), message)

    ## Then
    check await completionFutRelay.withTimeout(5.seconds)

    ## Cleanup
    await allFutures(lightNode.stop(), bridgeNode.stop(), destNode.stop())
