Systems and methods include, responsive to a request to test or troubleshoot a software system including a plurality of sub-components that communicate with one another via Application Programming Interfaces (APIs), creating one or more gadgets that one or more of inject data in any sub-component and probes responses from any sub-component; performing one or more tests of one of more of the plurality of sub-components utilizing the one or more gadgets to invoke specific behavior of the software system and to collect internal data to examine correctness of the behavior; and subsequent to the one or more tests, removing the one or more gadgets. The one or more gadgets are non-intrusive and do not alter behavior of the plurality of sub-components.

Packet switch test methods include receiving a first packet from a packet switch, receiving a second packet from processing circuitry configured to model expected behavior of the packet switch, comparing the first packet to the second packet, and, based on the comparing, determining whether the packet switch is operating according to the expected behavior. Packet switch modeling methods include identifying functionality of a packet switch to be modeled, creating, in a packet switch model, a plurality of nodes representing physical and/or logical elements of the packet switch, the nodes being configured to process packet data structures and to respectively model different portions of the functionality of the packet switch relative to one another, and, in the packet switch model, connecting the nodes with pathways by which the packet data structures may be forwarded between the nodes.

Packet data structure formation methods include receiving a request to create a data structure for representing a packet. The request may refer to two or more fields to be included in the packet. The methods further include determining bit values and packet positions associated with the fields and, based on the determining, creating a set of bits comprising the packet. The set of bits include the bit values in the packet positions. The method further includes storing the set of bits using the data structure.
