Hi,

I have been looking at the MQTT Conformance/Interoperability Testing project and have a few questions when it comes to conformance testing of a client. From what I understand I should use the model broker and run tests against that broker to measure the specification coverage of the tests.
Are there any test cases implemented and/or specified for clients to use?
Will some of the Client Test column tests in the MQTT Tests excel be implemented or is it up to each client to implement its own test cases?
Will the Statement No in the excel file be updated to the released 3.1.1 standard instead of the Draft version that is currently used?

Hi,

yes, you can use the model broker to run the client against. It will tell you on termination which conformance statements have been encountered during the testing. My original goal was to generate an abstract test suite which would apply to any client library. To run against a specific library then this abstract suite would have to be translated to the API of the library.

At this point, you can write your own test suite, and the model broker will give you an idea of the completeness of your testing. The coverage matrix in the spreadsheet is really a minimal coverage set, a stepping stone to the complete coverage suite which I have not yet achieved.

There is also a specific Eclipse IoT Testware project which you might like to look at: https://projects.eclipse.org/proposals/eclipse-iot-testware
