    ## Setup
    let
      lightNodeKey = generateSecp256k1Key()
      lightNode = newTestWakuNode(lightNodeKey, ValidIpAddress.init("0.0.0.0"), Port(0))
      bridgeNodeKey = generateSecp256k1Key()
      bridgeNode = newTestWakuNode(bridgeNodeKey, ValidIpAddress.init("0.0.0.0"), Port(0))
      destNodeKey = generateSecp256k1Key()
      destNode = newTestWakuNode(destNodeKey, ValidIpAddress.init("0.0.0.0"), Port(0))

    await allFutures(destNode.start(), bridgeNode.start(), lightNode.start())

    await destNode.mountRelay(@[DefaultPubsubTopic])
    await bridgeNode.mountRelay(@[DefaultPubsubTopic])
    await bridgeNode.mountLightPush()
    lightNode.mountLightPushClient()

    discard await lightNode.peerManager.dialPeer(bridgeNode.peerInfo.toRemotePeerInfo(), WakuLightPushCodec)
    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(DefaultPubsubTopic, message)

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

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