A method of communicatively coupling groups of devices from a plurality of devices under test (DUTs) communicatively coupled to a respective one of a plurality of switching elements of a DUT controller, so that each group of DUTs have an opportunity to test their design, interoperability, and/or standards compliance between each other, the method comprising: (i) identifying a first DUT and a second DUT from among the plurality of DUTs as members of a test group, wherein the first DUT and the second DUT are identified based upon a test schedule defining a plurality of test groupings of members of the plurality of DUTs for concurrent testing; (ii) communicating control instructions to a first switching element coupled to the first DUT and to a second switching element communicatively coupled to the second DUT, wherein the control instructions are configured to actuate the first switching element and the second switching element to communicatively couple the first DUT and the second DUT without communicatively coupling them to other DUTs; (iii) accessing the test schedule residing in a computer-readable storage medium, wherein the test schedule identifies a test duration in the test schedule, and wherein the test duration defines at least a start of the test where the testing between the first DUT and the second DUT is scheduled to begin; (iv) wherein the first DUT is automatically communicatively coupled to the second DUT at the start of the test duration; (v) wherein the test duration further defines at least an end of the test where the testing between the first DUT and the second DUT is scheduled to conclude, wherein the control instructions configured to actuate the first switching element and the second switching element to communicatively couple the first DUT and the second DUT are first control instructions, and further comprising: (vi) monitoring the test schedule to identify the end of the test duration; and (vii) communicating second control instructions to the first switching element coupled to the first DUT and to the second switching element communicatively coupled to the second DUT, wherein the second control instructions are configured to actuate the first switching element and the second switching element to communicatively decouple the first DUT and the second DUT; the method further comprising: in parallel, performing steps (i) to (vii) for a different test group of DUTs. (i) identifying a first DUT and a second DUT from among the plurality of DUTs as members of a test group, wherein the first DUT and the second DUT are identified based upon a test schedule defining a plurality of test groupings of members of the plurality of DUTs for concurrent testing; (ii) communicating control instructions to a first switching element coupled to the first DUT and to a second switching element communicatively coupled to the second DUT, wherein the control instructions are configured to actuate the first switching element and the second switching element to communicatively couple the first DUT and the second DUT without communicatively coupling them to other DUTs; (iii) accessing the test schedule residing in a computer-readable storage medium, wherein the test schedule identifies a test duration in the test schedule, and wherein the test duration defines at least a start of the test where the testing between the first DUT and the second DUT is scheduled to begin; (iv) wherein the first DUT is automatically communicatively coupled to the second DUT at the start of the test duration; (v) wherein the test duration further defines at least an end of the test where the testing between the first DUT and the second DUT is scheduled to conclude, wherein the control instructions configured to actuate the first switching element and the second switching element to communicatively couple the first DUT and the second DUT are first control instructions, and further comprising: (vi) monitoring the test schedule to identify the end of the test duration; and (vii) communicating second control instructions to the first switching element coupled to the first DUT and to the second switching element communicatively coupled to the second DUT, wherein the second control instructions are configured to actuate the first switching element and the second switching element to communicatively decouple the first DUT and the second DUT;
