Metrics used in Testing


Defect Metrics

Analysis on the defect report is done for management and client information. These are categorized as

Defect Age: Defect age is the time duration between the point of introduction of defect to the point of closure of the defect. This would give a fair idea on the defect set to be included for smoke test during Regression
                                   
Defect Analysis: The analysis of the defects can be done based on the severity, occurrence and category of the defects. As an example Defect Density is a metric which gives the ratio of defects in specific modules to the total defects in the application. Further analysis and derivation of metrics can be done based on the various components of the defect management.

Test Management Metrics

Analysis on the test management is done for management and client information. These are categorized as

Schedule: Schedule Variance is a metric determined by the ratio of the planned duration to the actual duration of the project.

Effort: Effort variance is a metric determined by the ratio of the planned effort to the actual effort exercised for the project.
