|Re: [paho-dev] Paho Clients Conformance Testing|
I am interested in your work. It has (long) been a goal of mine
to generate abstract test suites for MQTT client libraries (and
brokers. Obviously for brokers the MQTT protocol can be used
directly but as you point out for client libraries translation
into concrete API calls is needed.
Perhaps we could have a video call in January so that you could demonstrate and we could discuss?
(I just tried to follow the Quickstart Guide, and had some
failures - it could be me, I don't know yet).
Hello Paho Enthusiasts,
some of you might already have heard about the Eclipse IoT-Testware project.
Within the IoT-Testware we have also MQTT v3.1.1 Conformance Tests für Brokers and Clients.
However, while testing Brokers is quite straightforward, testing Clients is a bit more challenging. The reason, MQTT Client libraries are required to be triggered by an application. So for conformance testing, we required some sort of a testing application which can trigger the Implementation Under Test (IUT) on behalf of the Test System (TS). Such a testing application can be imagined as remote control (to be precise the receiver of an RC), though we call the concept Upper Tester (UT) which is sketched in the attached (mqtt_client_testing.png) picture.
The IoT-Testware has already the TS side of the UT (the RC itself) and a simple JSON definition for the PCO (Point of Control and Observation), let's imagine this one as the RC protocol.Well, while the TS is complete from this perspective, we still require RC receivers (UT part on the IUT side).For testing purposes, I have built UTs for two of the available Paho clients (Java and Python) and looking now for a new home for these components.
Have you any ideas on how we could manage that and if cooperation between IoT-Testware and Paho would be beneficial? Maybe as an addition to Paho's Interoperability Testing efforts?
