Abstract

The invention belongs to the field of primary and secondary peak value ratio calculation algorithm testing, and particularly relates to a metamorphic testing system of a primary and secondary peak value ratio calculation algorithm. The system comprises a metamorphic relation extraction module, an additional test case generation module and a verification module. The metamorphic relation extractionmodule is used for extracting a metamorphic relation according to a regional image and a neighborhood image input by a primary-secondary peak ratio calculation algorithm; the additional test case generation module is used for combining the original test case with the metamorphic relationship to generate an additional test case, and outputting the additional test case to the verification module; and the verification module is used for inputting the original test case and the additional test case into the tested program and verifying whether the tested program has defects or not. Compared with the prior art, the metamorphic testing system is derived from geometric attributes, numerical attributes and algorithm characteristics in the algorithm, so that an absolutely accurate expected result does not need to be obtained, and the problem of test judgment uncertainty of a reconstructed standard model can be well solved.

Description

technical field [0001] The invention belongs to the field of primary and secondary peak ratio calculation algorithm testing, and in particular relates to a transformation test system for primary and secondary peak ratio calculation algorithms.
