Method and apparatus for test modeling

A system having a processor, the processor being adapted to perform the steps of:

• receiving a partial description of a combinatorial model, the combinatorial model defining a test space, the combinatorial model comprising a set of attributes, a respective domain for each attribute defining possible values for the attribute, wherein each restriction comprises at least one attribute, a respective value thereof and a logical operator, wherein the partial description comprising at least one attribute of the set of attributes and at least one value for the at least one attribute;
• computing a similarity measurement between the partial description and each model in a corpus of existing combinatorial models, wherein the similarity measurement is computed based on similarity of attributes and respective domains thereof and not based on the test space defined by models being compared, whereby similarity between models is indifferent to a size of the test space of the models;
• selecting one or more selected models from the corpus of existing combinatorial models in accordance with similarity measurements computed for the existing combinatorial models;
• determining one or more elements from selected models to be provided as a modification suggestion for modifying the partial description;
• and
• outputting the modification suggestion to modify the partial description based on the one or more elements, whereby the modification suggestion is useful in completing the partial description to create the combinatorial model.

A computer program product comprising a non-transitory computer readable medium retaining program instructions, which instructions when read by a processor, cause the processor to perform a method comprising:

• receiving a partial description of a combinatorial model, the combinatorial model defining a test space, the combinatorial model comprising a set of attributes, a respective domain for each attribute defining possible values for the attribute, wherein each restriction comprises at least one attribute, a respective value thereof and a logical operator, wherein the partial description comprising at least one attribute of the set of attributes and at least one value for the at least one attribute;
• computing a similarity measurement between the partial description and each model in a corpus of existing combinatorial models, wherein the similarity measurement is computed based on similarity of attributes and respective domains thereof and not based on the test space defined by models being compared, whereby similarity between models is indifferent to a size of the test space of the models;
• selecting one or more selected models from the corpus of existing combinatorial models in accordance with the similarity measurements computed for the existing combinatorial models;
• determining one or more elements from the one or more selected models to be provided as a modification suggestion for modifying the partial description;
• and
• outputting the modification suggestion to modify the partial description based on the one or more elements, whereby the modification suggestion is useful in completing the partial description to create the combinatorial model.
