测试用例颗粒度说明
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate ，所以你需要指明功能、性能需求，使用环境等，并说明对缺陷容忍的限度。才好依据最终的需求来定义测试的颗粒度，也才好写测试用例，总之，客户的要
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured

求越详细所得到的测试用例越准确。如果客户跟你说这个地方你必须仔仔细细的测试。那么我们在写测试用例的时候。这个颗粒度一定要小了。
3、一般功能颗粒密集度可能会根据工程或是时间来确定。如果时间充裕颗粒度可以适当小。
4、粒度取决于测试的种类，一般用验收测试,是工程测试中颗粒度比拟大。系统测试颗粒度相对较小。
有效度量测试用例条件：
1、颗粒度可以跟代码行数对应：一般来说代码量越大，内部逻辑就越复杂，出现bug的的
