Quality of fixes is the ratio of difference of Total no. of Defects reported as fixed and Total no. of reopened defects to sum of Total no. of Defects reported as fixed and Total no. of new defects due to fix.
Quality of fixes metric is used to determine the quality of fix done by development team. Lower the value indicates the poor quality of defect fixes.
It is measured during each build and end of test execution phase.
How to calculate the Quality of fixes:
Quality of fixes = (Total no. of Defects reported as fixed -Total no. of reopened defects) / (Total no. of Defects reported as fixed + Total no. of new defects due to fix)*100
Example:
Total no. of fixed defects
|
Total no. of reopened defect
|
Total no. of new defects due to fix
|
Quality of fixes
|
100
|
5
|
2
|
93.13
|
Quality of fixes = (100-5) / (100+2) * 100
= 93.13 %
