How do you analyze your test results? What metrics do you try to provide?

Test results are analyzed to identify the major causes of defect and which is the phase that has introduced most of the defects. This can be achieved through cause/effect analysis or Pareto analysis. Analysis of test results can provide several test matrics. Where matrices are measure to quantify s/w, s/w development resources and s/w development process. Few matrices which we can provide are: 

Defect density: total no of defects reported during testing/size of project.

Test effectiveness'/(t+uat).
where t: total no of defect recorded during testing.

and UAT: total no of defect recorded during use acceptance testing.

Defect removal efficiency(DRE): (total no of defect removed / total no of defect injected)*100.
