This paper introduces the notion of Constrained Locating Arrays (CLAs), mathematical objects which can be used for fault localization in a testing process for information systems. CLAs extend ordinary locating arrays to make them applicable to testing of systems that have constraints on test parameters. Such constraints are common in real-world systems; thus CLA enhances the applicability of locating arrays to practical testing problems.

用于组合交互测试的约束定位阵列

本文介绍了约束定位阵列 (CLA) 的概念，这是一种数学对象，可用于信息系统测试过程中的故障定位。CLA 扩展了普通定位阵列，使其适用于对测试参数有限制的系统的测试。这种约束在现实世界的系统中很常见；因此，CLA 增强了定位阵列对实际测试问题的适用性。
