/**
|
|
|
|
|
* A basic unit test that builds a flow containing 1 broker, 1 mqtt-in, one mqtt-out and a helper.
|
|
|
|
|
* It performs the following steps: builds flow, loads flow, waits for connection, sends `sendMsg`,
|
|
|
|
|
* waits for msg then compares `sendMsg` to `expectMsg`, and finally calls `done`
|
|
|
|
|
* @param {object} brokerOptions anything that can be set in an MQTTBrokerNode (e.g. id, name, url, broker, server, port, protocolVersion, ...)
|
|
|
|
|
* @param {object} inNodeOptions anything that can be set in an MQTTInNode (e.g. id, name, broker, topic, rh, nl, rap, ... )
|
|
|
|
|
* @param {object} outNodeOptions anything that can be set in an MQTTOutNode (e.g. id, name, broker, ...)
|
|
|
|
|
* @param {object} options an object for passing in test properties like `sendMsg` and `expectMsg`
|
|
|
|
|
* @param {object} hooks an object containing hook functions...
|
|
|
|
|
* * [fn] `done()` - the tests done function. If excluded, an error will be thrown upon test error
|
|
|
|
|
* * [fn] `beforeLoad(flow)` - provides opportunity to adjust the flow JSON before loading into runtime
|
|
|
|
|
* * [fn] `afterLoad(helperNode, mqttBroker, mqttIn, mqttOut)` - called before connection attempt
|
|
|
|
|
* * [fn] `afterConnect(helperNode, mqttBroker, mqttIn, mqttOut)` - called before connection attempt
