DRE¶
什么是DRE¶
DRE: Defect Removal Efficiency
DRE is a measure to detect defects before delivery.It is calculated as a percentage of the defects identified and corrected internally with respect to the total defects in the complete project life cycle. Thus, DRE is the percentage of bugs elimiated by reviews, inspections, tests etc.
准确来说，DRE能够反映测试团队的效率以及产品的质量。数值越高，表示的是测试团队漏掉的bug很少，产品出现issue的问题就越低。
扩展¶
- 可以根据severity或者priority来进行相应level的DRE的计算。比如Defect_Removal_Efficiency
- 1-DRE: 实际上，这样计算出来的就是defect的漏测率。
- DRE时间段的选择。在现在敏捷或者持续集成的project里面，很难计算出准确的before和after release的defect数量。换一种方式的话，就是选择90天内的defect数量在进行比较，可以得出一段时间内的DRE。
