摘　　要：在研究等价类测试时,可以根据可靠性理论的健壮性和单/多缺陷假设,将等价类划分为弱一般等价类、强一般等价类、弱健壮等价类和强健壮等价类四种,其中弱健壮等价类就是传统软件工程所讨论的等价类测试方法。等价类测试的数学基础是等价关系和划分,划分保证了等价类测试的完备性和无冗余性。在分析等价关系时,只要计算出集合上的划分即可。文中给出了划分的实例,表明了从划分研究等价关系的合理性。提出了等价类设计的原则和等价类测试用例的设计方法。There are two factors of equivalence class in reliability theory, one is robustness, and the other one is single or multiple defects, these two factors are used in the study of equivalence. The equivalence class is divisible into four types according to these two factors, which are weak equivalence, strong equivalence, weak robust equivalence and strong robust equivalence. The weak robust equivalence is discussed in software engineering. The equivalence relations and partition are the basis of the equivalence testing. Partitioning guarantees the completeness and non - redundancy of equivalence testing. Study on the partitioning based on set is must when study equivalence. The partitioning example is provided in the paper, and it is available that the equivalence is equal to partitioning. The principle of equivalence testing is provided, and the test cases of equivalence testing are designed.
