Communication system tester and related methods

A method of testing a communication device, the method comprising:

• providing a communication device tester comprising a communication subsystem comprising at least one port to interface with at least one test device;
• generating, using a traffic disciplining subsystem of the communication device tester, a first stream of data packets satisfying a metric and communicating the first stream of data packets to the at least one test device using the communication subsystem in a first test scenario;
• generating, using a delay subsystem of the communication device tester, a variable delay in a second stream of data packets and communicating the second stream of data packets to the at least one test device using the communication subsystem in a second test scenario;
• corrupting, using a data corruption subsystem of the communication device tester, a third stream of data packets and communicating the third stream of data packets to the at least one test device using the communication subsystem in a third test scenario;
• and
• determining, using a test subsystem of the communication device tester, whether the test device satisfies at least one criterion associated with the first test scenario, the second test scenario, and the third test scenario.
