Methods and data structures are disclosed for a program module (e.g., API) test matrix generator system/process. The disclosed methods and data structures facilitate and carry out a streamlined, yet logically thorough test to verify the proper operation and/or expose errors within the program module under test. The method comprises breaking a set of input parameters to the program module into clusters of related parameters (i.e., parameters whose values affect each other's validity regarding the output of the program module). Thereafter, a set of groups, representing different usages of a set of clustered parameters, are identified. After identifying the groups, a set of test calls (or a test matrix) is rendered for the program module. A covering set of test calls for a particular cluster comprises a sum of all logically/operationally distinct input value combinations rendered for each group. Such distinct input value combinations are rendered according to parameter equivalence classes defined for each parameter of each one of the cluster's groups. An actual test call includes a representative set of parameter values for a particular selected combination of equivalence classes.

Method and system for generating test matrices for software programs

A method and system for managing the transfer of message packets between first and second nodes in a message queuing system utilizes a session acknowledgment protocol to coordinate the two-way flow of packet transmission. In a session initiation phase, each node specifies a session acknowledgment timeout period and a transmission window size for transmission of message packets thereto. During the session, the first node transmits multiple message packets up to the window size set by the second node and stops to wait for a session acknowledgment from the second computer. The session acknowledgment may piggyback on a message packet sent to the first node. A window-size field in the session acknowledgment allows the receiving node to dynamically adjust the incoming data flow.
