Derivation of generalized test cases

A computer program product for creating a generalized test case, the computer program product comprising:

• one or more computer-readable storage devices and program instructions stored on at least one of the one or more computer-readable storage devices, the program instructions comprising:
• program instructions to receive one or more pre-defined equivalence classes, wherein a pre-defined equivalence class comprises of one or more substantially equivalent values;
• program instructions to receive a plurality of messages transmitted between a second computer and a third computer, wherein each message of the plurality of messages has at least one parameter and each parameter has at least one corresponding value;
• program instructions to determine one or more parameters contained in the plurality of messages has one or more corresponding values that match one or more values of a pre-defined equivalence class;
• program instructions to create one or more value driven equivalence classes, wherein each value driven equivalence class comprises of one or more parameters and, wherein each of the one or more parameters in each value driven equivalence class has the same corresponding value;
• and
• program instructions to create a generalized test case, wherein the generalized test case includes at least the one or more value driven equivalence classes.

A computer system for creating a generalized test case, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising:
• program instructions to receive one or more pre-defined equivalence classes, wherein a pre-defined equivalence class comprises of one or more substantially equivalent values;
• program instructions to receive a plurality of messages transmitted between a second computer and a third computer, wherein each message of the plurality of messages has at least one parameter and each parameter has at least one corresponding value;
• program instructions to determine one or more parameters contained in the plurality of messages has one or more corresponding values that match one or more values of a pre-defined equivalence class;
• program instructions to create one or more value driven equivalence classes, wherein each value driven equivalence class comprises of one or more parameters and wherein each of the one or more parameters in each value driven equivalence class has the same corresponding value;
• and
• program instructions to create a generalized test case, wherein the generalized test case includes at least the one or more value driven equivalence classes.
