Abstract

The present disclosure relates to system(s) and method(s) for testing a Constrained Application Protocol (CoAP) server and a plurality of resources hosted over the CoAP server. The system is configured to identify a plurality of URI links corresponding to the plurality of resources hosted over the CoAP server, wherein each URI link from the plurality of URI links is configured to store a set of parameters associated with each resource from the plurality of resources. The ‘rt’ is a field to indicate type of each resource and also to distinguish between a sleeping node resource or a non-sleeping node resource. Further, a plurality of test cases configured to test the plurality of resources is generated by sending CoAP requests messages based on the set of parameters associated with the resources and the test configuration. Finally during testing the system takes into account whether a particular resource is a sleeping-node or not.
