Software testing, undoubtedly, is the most critical parameter of the whole software development and deployment cycle. However, what is more important is to monitor the metrics of the testing activities and understand how it is performing. In short, software testing metrics are statistical methods used to measure the reliability, effectiveness, and development of the software testing process. It allows to collect accurate information about the software process and understand the gaps arising in achieving the expected outcome, thereby, improving its performance.
Software testing metrics allows organizations to make accurate and precautionary decisions based on the data available, helping to improve the process. When the process is understood based on the factual data and changes are implemented accordingly, it will surely give accurate results and improve the quality.
Everything you should know about software testing metrics
Software metrics is not a mere reporting approach for the testers, but it offers scope beyond that. It can be used to streamline the entire software development process by giving insights to the developers as where the gap lies and estimates on how long it will take to complete the development process. It also gives an overview of the number of new features added, the alterations made, and the other changes implemented, allowing to understand the application better.
A metric represents the volume, number, proportion, or length of a software or application’s specific feature. A titrate imputation of the software’s feature or system development process is referred to as software measurement, a renowned authority in the field of software engineering. ISO Standard defines and governs the software measuring processes; this is one of the critical parameters to understand the quality. Software development companies need to measure the software features to make it stand out in the current market and fulfil user requirements efficiently.
Reasons for implementing software metrics are:
- Evaluate all sorts of necessary improvements to provide a bug-free, high-quality software product; allowing companies to deliver high-quality products with the best features and high accuracy, increasing the market demand.
- Make informed judgments regarding the testing stages that follow, such as organizing the following projects and calculating the total cost of those initiatives. Through the testing phase, organizations can anticipate the improvement in the software development of the following software product.
- Examine the existing technologies or procedures to see whether they need any additional changes. It also lets the organizations regulate the software development stage in coordination with the budget and the schedule.
Software testing metrics classification
Software testing metrics can be classified into different types based on the kind of data they provide. Different types of software testing metrics include:
Product metrics is the measurement of software products at every stage of growth, from specifications through fully operational systems, where only technical aspects are taken into consideration. Product metrics are intended to assess the current condition, identify risks, and uncover potential issue areas. The league’s capacity to maintain quality is assessed. Metrics are acquired dynamically as a result of measured values during the project’s implementation phase.
Dynamic metrics aid in determining a program’s effectiveness and reliability. Software quality criteria are strongly tied to dynamic measurements. It is pretty simple to determine the time possible to begin the systems and assess the implementation time needed for specific processes. These are heavily linked to the effectiveness of malfunctions, and the failure mode can be reported, as well as the software’s dependability.
Measurements obtained from software representations such as architecture, code, or metadata collect static metrics. They aid in comprehending, being capable of understanding, and managing a computer system’s complexities. Quality aspects and features indirectly influence the static metrics.
Many static metrics have been presented to develop and confirm the link between complexities, easing understanding, and manageability. Among the static metrics that have been used to evaluate quality features, programs, or module sizes and controlling complexities appear to be the most reliable indicators of interpretability, computational power, and manageability.
Process metrics is focused on improving the organization’s long-term processes. Process metrics is the measurement of the system development life cycle. The time it takes to complete software development activities is a frequent illustration of a workflow measure. It can predict, analyze, and optimize software dependability and performance predicated on the theory that the integrity of the result is a linear consequence of the process.
Project metrics can be defined as the metrics that determine the project characteristics and process execution. It consists of variables such as the total number of software developers included in the process, staffing pattern, cost of the software process, process scheduling, software productivity, etc.
Project metrics consist of various variables such as the developers’ coding and programming language experience, development methods used in the software development, communication methods, team spirit and team efficiency, management experience, and others. In terms of productivity, quality versus productivity is the main feature.
Determining the software testing metrics is an important part of the testing process. Only detailed metric data can help the testers to understand the efficiency and efficacy of the testing process being used. If the metrics is not supporting the effectiveness of the process or a part of the process, it is an indication to the testers to implement another process to improve the quality. In short, software testing metrics evaluates the process efficiency and allows to identify measures that can improve the effectiveness of the existing process. The insights obtained by the metrics helps the team to make the right decisions and apply the same to future projects too. Software metrics help organizations in creating quality-driven processes, which in turn offers seamless customer experience and improve ROI.
