First design a reasonable XML Schema structure and under the restriction of XML Schema use XML to describe the UML class diagram and the related specification, and then extract the test specification of method from XML test script. Test specification refers to predicate sequences in the form of conjunctive normal form, extracted from basic constraint conditions of variables included in test scripts and expected outputs. Each conjunctive normal form can be transformed to an inequation set, and adopt 1×1 domain test strategy to every inequation set to produce the domain test matrix, which in turn produce the test case.
