等价类划分测试用例设计

Sample Design of Equivalence Division Test

等价类划分是黑盒测试的典型方法之一，通过把被测试程序所有可能的输入数据域划分成若干部分。从每一部分中选取少数有代表性的数据作为测试用例，可有效减少测试次数，极大提高软件测试效率，缩短软件开发周期．

Equivalence class division is one of the typical test methods of black box. To divide all the data in the program to be tested into several parts and take from each part a few representative data as test sample can effectively reduce test times, improve software test effeciency and shorten software development cycle.
