基于正交实验法的Web测试用例设计

Web test case design based on orthogonal experiment

正交实验法是从日本引进的一种科学方法,利用正交表,可以科学地安排多因素场景下,进行实验,用最少的实验次数,达到最好的实验效果。该实验法实际上就是一种优选法,不仅可以解决海量因素如何择优的问题,还可以用来分析各因素对实验结果影响的大小,从而识别出主要因素。本文主要研究和介绍了正交实验法的基本概念和原理,并通过实际案例,讲解如何运用该实验法,完成测试设计,同时说明怎样确定测试因子和水平,怎样选正交表以及测试用例生成和完善的过程。

Orthogonal experiment is a scientific method introduced from Japan.By using orthogonal table,we can scientifically arrange experiments under multi factor scenes,and achieve the best experimental effect with the least number of experiments.The experimental method is actually a kind of optimization method,which can not only solve the problem of how to choose the best mass of factors,but also be used to analyze the influence of various factors on the experimental results,so as to identify the main factors.This paper mainly studies and introduces the basic concept and principle of orthogonal experiment method,and through the actual case,explains how to use the experimental method to complete the test design,at the same time explains how to determine the test factor and level,how to select the orthogonal table,and the process of test case generation and improvement.
