Introduction to Software Metrics:

Testing the quality, effectiveness, and cost of a software project and processes is extremely important and without measuring these aspects, the project development cannot be fully completed. By implementing the practice of testing these elements, software engineers can ensure that no defects and errors are left undetected in the system as well as validate its functionality. This perfection of software testing can be achieved exceptionally by testing software metrics. Metrics can be defined as the standard of measurement, it is a unit used for describing and measuring attributes of a particular object or system. With the assistance of testing metrics, one can easily measure the software quality and ensure its performance. Graph, which is an integral part of Metrics in software testing, is used by testers to describe the various testing stages as well as the reports provided during the process of testing metrics of a software.

Graph Metrics in Software Testing:

Graphs are extremely beneficial as they summarize and display information in a manner that is easy for people to comprehend. This allows all the stakeholders of the project to understand all the element of the Metrics Testing easily, which further enables them to provide effective feedback. The purpose of graph metrics is to summarize the process of testing and the report generated at the end of Test Metrics Life Cycle. Other important elements represented through the graph are:

• Test completion status, defects raised and closed, issue type, work log distribution of testers per task and more.
• Test execution completion percentage. It represents the total number of test cases executed.
• The generated detailed summary reports for projects, milestones, plans, and runs are simplified and presented.
• Depicts number of passed, blocked, and failed test cases. The numbers of cases that require retesting are also illustrated.
• Testers also use graph metrics in software testing to depict the remaining tests, remaining efforts, as well as the track the ideal progress.
• The cost and efforts are monitored and represented.
• Represents the defect status provided by priority: critical, high, medium and low.

Summary:

The test metrics should be reviewed and interpreted throughout the test effort regularly and particularly after the application is released into production. It provides a quantitative approach to measure the quality and effectiveness of the software development and testing process. Test Metrics provides visibility into the readiness of the product and gives clear measurement of its completeness.

By testing metrics the team of developers and testers can monitor the improvements and changes in the software and ensure that its quality, performance, and features are as per the demands of the client. Moreover, with the use of graph metrics in software testing, the developers and testers can represent the status report and other elements of the software development process by summarizing and simplifying them. Because of these benefits and advantages, Metrics in software testing is rapidly becoming popular among software developers and testers all around the world, which is allowing them to deliver products of high quality.
