Generating and aggregating test result data of a distributed system of devices into a test case result for facilitating access of the test case result via a single iterator is presented herein. A coordinator component of the distributed system of devices creates respective context identifiers for each unique phase of a test case of the distributed system of devices, and sends messages including the respective context identifiers to a producer component of the distributed system of devices. In this regard, the producer component includes producers having respective services executing processes corresponding to an execution of the test case. The messages instruct the respective services to associate the respective context identifiers with events representing result data of the processes, and the respective context identifiers facilitate respective accesses of the events representing the result data of the processes.
