估计测试工作量占开发时间的百分比 [英] estimating of testing effort as a percentage of development time

问题描述

是否有人使用经验法则来估计测试所需的工作量占开发所需工作量的百分比?如果是这样，您使用的百分比是多少?

Does anyone use a rule of thumb basis to estimate the effort required for testing as a percentage of the effort required for development? And if so what percentage do you use?

推荐答案

根据我的经验，25% 的精力花在分析上；50% 用于设计、开发和单元测试；剩余 25% 用于测试.根据项目的性质、资源的知识、投入的质量，大多数项目都在这个经验法则的 +/-10% 范围内.产出等.您可以在这些百分比范围内添加项目管理开销，或者在 10-15% 范围内作为顶部开销.

From my experience, 25% effort is spent on Analysis; 50% for Design, Development and Unit Test; remaining 25% for testing. Most projects will fit within a +/-10% variance of this rule of thumb depending on the nature of the project, knowledge of resources, quality of inputs & outputs, etc. One can add a project management overhead within these percentages or as an overhead on top within a 10-15% range.
