Methods, systems, and computer readable media for testing data processing units in high availability configurations

A system for testing a collection of distributed highly available (HA) data processing units (DPUs) in a data center, the system comprising:

• a test packet generator configured for generating test traffic and transmitting the test traffic towards an HA DPU pair;
• a test controller configured for executing, while the data center is operating with live traffic, a test case and controlling the test packet generator to cause a failover test event at the HA DPU pair by sending selected traffic to the HA DPU pair that causes an anomaly at the HA DPU pair and causes the HA DPU pair to detect the anomaly and initiate a switching event from a first HA DPU to a second HA DPU in response to detecting the anomaly;
• and
• a monitoring module, deployed on at least one DPU of the HA DPU pair, and configured for monitoring the HA DPU pair during the failover test event and reporting one or more metrics characterizing the failover test event to the test controller.
