ETSI has released a first set of seven standards addressing the testing of the IoT MQTT and CoAP protocols, and the foundational security IoT-Profile.
The ETSI TS 103 596 series provides an overall test suite structure and catalogue of test purposes for the Constrained Application Protocol (CoAP).
The ETSI TS 103 597 series provides an overall test suite structure and catalogue of test purposes for the MQ Telemetry Transport (MQTT).
ETSI TS 103 646 specifies testing for selected security requirements as known in the IEC 6244-4-2 standard.
All Test purpose catalogues have been produced using the Test Description Language (TDL-TO) specified in ETSI ES 203 119-4.
