Test metrics is a mechanism to know the effectiveness of
the testing that can be measured quantitatively. It is a
feeback mechanism to improve the testing process.
They are collected at each phase of the etsting lifecycle.
Adv : 1. Better knowledge of the project.
2. Identify risk areas that requires more testing.
3. Measure of effectiveness and efficiency of testing.
5 Testing metrics :
1. Defect by action taked :
This metrics is an indicator of the effectiveness of the
testing process and test execution . Good percentage of
defects marked as "Rejected" implies that the understanding
of the test engineer on the functionality is low.
2. Defect by injection phase :
Indicator of the most problematic phase in the s/w dev.
Like Design, coding, Documentation, Test planning etc..
3. Defects by Detection phase.
Indicator of the most efficient phase of s/w dev. in terms
of finding and removing bugs.
Hope u hv an idea now.... :)
Some other test metrics
4. Defects by priority
5. Defects by severity
6. Time to find a defect
7. Time to resolve a defect
8. Test case effectiveness
9. Defect / KLOC
10.Bad fix ratio..
and there are a lot more.. :)
