Abstract

A first computer receives a first and a second test sample. The first computer executes the first and second test sample. The first computer determines that the value exposed by a first parameter in the second test sample is different from the value exposed by the first parameter in first test sample. The first computer creates a first value driven equivalence class. The first computer determines the value exposed by the second parameter in the second test sample is different from the value exposed by the second parameter in the first test sample and the value exposed by the second parameter in the second test sample is equivalent to the value exposed by the first parameter in the second test sample. The first computer adds the second parameter to the first value driven equivalence class and creates a generalized test case, including at least the first value driven equivalence class.

Dependent claims

A method for creating a generalized test case, comprising the steps of:

a first computer receiving a first and a second test sample, wherein each test sample contains the same plurality of messages, and each message contains one or more parameters, and each parameter has at least one corresponding value;
the first computer executing the first test sample, wherein each parameter in the first test sample exposes a corresponding value;
the first computer executing the second test sample, wherein each parameter in the second test sample exposes a corresponding value;
the first computer determining that the value exposed by a first parameter in the second test sample is different from the value exposed by the first parameter in first test sample;
the first computer creating a first value driven equivalence class, wherein the first value driven equivalence class contains the first parameter;
the first computer determining the value exposed by the second parameter in the second test sample is different from the value exposed by the second parameter in the first test sample;
the first computer determining the value exposed by the second parameter in the second test sample is equivalent to the value exposed by the first parameter in the second test sample;
the first computer adding the second parameter to the first value driven equivalence class;
and
the first computer creating a generalized test case, wherein the generalized test case includes at least the first value driven equivalence class.
