Software test metrics is to monitor and control process and product. A comprehensive guide: The release management process involves planning, scheduling, controlling, testing, and deploying releases. Traditional Testing principles are quite often used in Agile Testing. Some of the Software test release related metrics are as below. 2. Metrics can fall into several categories: Metrics measuring the status of testing % of tests executed % test plan complete; Metrics measuring the effectiveness of testing Availability of test environment; Defect age; Number of defects found after release vs number found before release; Metrics measuring quality % of test coverage % of tests passed Metrics can be defined as “STANDARDS OF MEASUREMENT”. The role of the tester is to use the software like the end user would, and then identify problems and mitigate them to ensure optimum functionality of the Software. 1. By this testing method, it reduces the time required for software testing. The most common static software QA methodologies are audits, walkthroughs analysis of metrics, technical review, management evaluation, inspection, and others. This article based on my experiences and understanding. Defect cycle time—quick software release times are important in a fast-paced Agile team. Escaped defects metrics help in bug identification when a release enters production. Although there are numerous metrics for software testing, and new ones being proposed frequently, relatively few are supported by sufficient experiences of industry implementation to demonstrate their usefulness. 4. If you collect and focus on too many, they may be obstructing your field of view.”. Estimated Release Downtime -When the product is about to release, if there is a need to update the database or migrate to larger datasets, the team needs to capture a release downtime in the timeline. Upon approval of the request, the team designs the new release and planning begins. A burndown report communicates the complexion of work throughout the sprint based on story points. Metrics can be categorized as below. Types Of Manual Test Metrics. Software testing metrics are the means through which one can measure the quality of software. The list features tips and insights from experts on many of the less black-and-white aspects of testing. •User testing, where users or potential users of a system test the system in their own environment. Tip: Some of your most important software testing metrics may be available ONLY after a project is done (external to the testing process) but should be included: Escaping Defects, Rejected Defects, Server Exception Levels, Support Calls Post-Release, etc. Make sure to set up monitoring to track your software’s performance before, during, and after your release. Reduced Total Security Tickets Opened Software Metrics Relative Size (wrt past work) Relative Complexity Degree of variation in product structure low risk domain 6. Software testing metrics need to be constantly reviewed for both accuracy and … Here is a list of 8 useful and effective software metrics the team must leverage 1. Test Case Productive Prepration 2. Test Execution Summary Summarize your reports with the following parameters such as 3. Test Case Coverage = [Executed Test cases / total no. of test cases] * 100 Defining the root cause of escaped defects helps prevent recurrence of the same issues in subsequent releases. You can assess the quality of the software in a raw form. Software test coverage goes beyond devices and operating systems. How many test cases are added for new release? So, an unreliable unit test would be one that’s not deterministic. As a QA manager, you are required to make a wise decision when it comes to selecting the agile testing metrics for your project or company. By keeping track of the average number of errors in each new software release, you can identify areas in your workflow that could be improved. Ultimately, the business results are going to be less than what we promised. There are no level 1 or 2 severity defects. Test Case Productive Prepration = Total test steps / effort (hours) e.g TPP = 60/8 = 7.5 8 test cases / hour. Test Case Passed; Test Case Failed •Release testing, where a separate testing team test a complete version of the system before it is released to users. The Developers perform the white box testing to test every line of the program's code and then send the application or the software to the testing team for further process. DevOps metrics are data points that directly reveal the performance of a DevOps software development pipeline and help quickly identify and remove any bottlenecks in the process. Software testing metrics gives insight about the efficiency and effectiveness of your software testing process. For example, you might realize that a new adding a new tool to your DevOps team’s arsenal can help your release smoother updates every time. These metrics can help plan budgets for testing activities and evaluate the ROI of testing. Therefore, the team will be better prepared for each upcoming release cycle. All the test cases should be executed atleast once. One of them is Early Testing that focuses on −. Though it may seem that measuring the KPIs is a natural thing to do, there is a divide between the people of the software testing community on the use of KPIs. Defect Density = Defect Count/Size of the Release/Module. Test provides the visibility into the readiness of the product , and gives clear measurement of the quality and completeness of the product. Software testing metrics are key for a Test Manager to understand, monitor and control the test phases across test levels.Proper use of software testing metrics is critical during any project and they are one of the test manager’s best allies in understanding where the testing is and which way it is heading within the project and across the organization.

Trends like automation, continuous testing, and DevOps have raised the bar by introducing speed and flexibility into the software development lifecycle (SDLC), and everyone is scrambling to keep up. Enabling Parallel Development with Service Virtualization. Product metrics – They measure product characteristics like density of defects or degree of testing. Software Test Coverage — Beyond Devices/OS. IEEE defines metric as 'a quantitative measure of the degree to which a system, component, or process possesses a given attribute.' The metric can help teams predict whether the users would recommend the software product or not. In this chapter from his book, Stephen Kan provides a detailed discussion of some tried and true in-process metrics from the testing perspective. It helps to drive the project towards our planned goals without deviation. Test Execution Summary . In this article, I will explain you several software testing metrics and KPIs and why we need them and how should we use them. Metrics provide insights into typical software behavior. Thereafter, the release moves into deployment, where it is made available for full use. 2. Release metrics. Project Metrics… This number should lead to investigation, retrospection, and corrective actions on improving the test set so the defect identification rate of the test set grows. Chapter 8 Software testing 16 Equivalence partitioning testing is a software testing technique which divides the application input test data into each partition at least once of equivalent data from which test cases can be derived. Examples include test case percentage that ran successfully, failed or were executed. Software Test Metrics used in the process of test preparation and test execution phase of STLC. The following are generated during the Test Preparation phase of STLC: It is used to calculate the number of Test Cases prepared and the effort spent for the preparation of Test Cases. If playback doesn't begin shortly, try restarting your device. Software Release Metrics. 3. Going back to the idea that the main activity of software testing and software QA is evaluation and measurement, metrics are not just an optional aspect of what we do as software quality practitioners. The goal of quality assurance is to ensure the highest possible quality of the software product. Measuring software product quality during testing by Rob Hendriks, Robert van Vonderen and Erik van Veenendaal 2. Software test coverage goes beyond devices and operating systems. Within Agile teams, test metrics provide feedback on testing efforts, areas that need improvement, and whether the testing processes achieve the vital Agile aim of high-quality software with frequent releases. Agile Productivity Metrics Example: If for a release the test effectiveness is 80%, it means that 20% of the defects got away from the test team. Testing Effectiveness Assessment (an article by Software Quality Consulting) 5. It has been tested with a test suite that provides 100% functional coverage, 80% branch coverage, and 100% procedure coverage. But in general, the following goals and metrics are a good place to start. They describe processes, without focusing too much on the product. This may help you catch mistakes earlier in the process. Software testing metrics are important for many reasons. Test effort estimation involves predicting the amount of test-related work needed in order to meet the objectives of testing a project, release or iteration leadership and is also one of the software testing basics for the test manager. Keywords—measurement, software testing, development In reality, measurements and metrics are the end result of what we do in software QA and testing.
