Equivalence Relation Theory In Software Test

摘要

The purpose of software test is to measure whether the software satisfies the demands, the choice of test methods and test cases directly affects software test results. Equivalence relation is reflexive, symmetry, transitivity . Equivalence class and classification produced by the equivalence relation is important in software test application. the theoretical basis of equivalence class testing is equivalence relation and division , it ensure the equivalence class test completeness and no redundancy by selecting test cases according to the nature of devision.
