Methods, systems, and computer readable media for testing a system under test (SUT). An example system includes a fabric emulation device configured for emulating a data center switching fabric using emulated switch queues and for emulating one or more congestion control mechanisms for network traffic on the data center switching fabric from the SUT. The system includes a test execution manager configured for: executing a test case causing the fabric emulation device to invoke at least a first congestion control mechanism; logging one or more metrics characterizing the first congestion control mechanism in response to invoking the first congestion control mechanism, wherein logging the one or more metrics comprises logging at least one performance metric from at least one emulated switch queue of the fabric emulation device; and outputting a test report based on logging the one or more metrics.

One example method occurs in a test environment comprising network emulation platforms (NEPs), wherein the NEPs implement an emulated switching fabric comprising emulated switches, wherein the NEPs are connected via at least one physical cable. The method includes determining, using a network test system controller, at least one routing path group for communications between the emulated switches, wherein each of the at least one routing path group includes or uses virtual links utilizing one or more lanes of the at least one physical cable; configuring, using the network test system controller, physical ports of the NEPs to assign traffic during a test session to one of the virtual links based on a routing path group identifier associated with the traffic; and initiating, using the network test system controller, the test session involving the test environment.

Methods, systems, and computer readable media for packet classification previewing are disclosed. Packet classification previewing is performed by a reserved preview packet classifier and initiated by a user. According to one aspect, a method for packet classification previewing includes providing a preview packet classifier. User input is received to classify packets using the preview packet classifier. In response to the user input, classification of packets is initiated using the preview packet classifier. Preview packet classification results are generated and displayed to the user, providing feedback as to whether the classifier configuration is correct or not as the user changes the configuration dynamically.
