Software testing metrics are quantifiable indicators of the progress, quality, and productivity of the testing process. Let’s discuss the devil in detail, Metrics are numbers that portray essential information about a process under question. Metrics ensure project deliverables, quantify the risk factors, and pursue process improvements. It enables customer satisfaction with high-quality products. Metrics also provide guidance for resource or budget estimation.
There are four major kinds of testing metrics:
Project metrics define where the team stands on the project and how close it is to achieving project objectives.It measures progress toward established project completion criteria, such as the percentage of test cases executed, passed, and failed before a release, sprint, or some other event. We can calculate one of the project metrics as mentioned below:
Percent of Test Case Execution = (Number of Passed Tests + Number of Failed Tests + Number of Blocked Tests) / Number of Test Cases
Product metrics in software testing determine whether product quality is on track for successful delivery. Some common product test metrics are mentioned below:
Total Percentage of Critical Defects = (Critical Defects / Total Defects Reported) x 100
Defect Distribution Across Components = Total Number of Defects / Functional area(s)
Process metrics measure the capabilities of product testing.Process metrics based on absolute numbers can include several measurements depending on your objectives and available data.Some Test metrics are mentioned below:
Percentage of Fixed Defects = (Defects Fixed / Defects Reported) x 100
Test Effectiveness Using Defect Containment Efficiency = Bugs Found in Test / Total Bugs Found (pre- and post-shipping) x 100
People metrics assess the skill level of the team as a whole and each member individually.It measure things such as issues per reporter or test cases executed by each team member.
Conclusion
The purpose of this article on test metrics is to enhance the QA process and reduce the risk of defects which ultimately ensures superior customer satisfaction.zs
