Beyond bug counts: Using KPIs for product quality and team morale

Performance tests may be written by developers and can also be a part of code review processes. Performance test case scenarios can be transported between environments — for example, between development teams testing in a live environment or environments that operations teams monitor. Performance testing can involve quantitative tests done in a lab or in production environments. Key performance indicators in software testing are the calculated data that help to measure the performance and effectiveness of testing. It gives an idea if the software testing is progressing in the right direction and whether it will be done on time.

The higher the number, the more CPU is being used; and the lower it is, the less time you’re spending on it. You can use an application like Task Manager or Windows Task Manager , which will show a graph showing how much CPU power each application you are testing has been using over time. You can use many other third-party tools to do the same thing. These indicators are absolute values generally used to determine the derivative metrics. These metrics are not self-sufficient to demonstrate the performance of a testing process.

How can you create a culture of KPI monitoring and improving?

Developers and IT staff may assume that the application works the same once it reaches the cloud. They might minimize testing and quality assurance, deciding instead to proceed with a quick rollout. Because the application is being tested on another vendor’s hardware, testing may not be as accurate as on-premises testing. Developers can carry out performance testing in the cloud as well.

Spike tests help determine if a system can handle an abrupt, drastic workload increase over a short period of time, repeatedly. Similar to stress tests, an IT team typically performs spike tests before a large event in which a system will likely undergo higher-than-normal traffic volumes. Soak testing, also called endurance testing, simulates a steady increase of end users over time to test a system’s long-term sustainability.

Cost per Detected Defect

Performance testing gathers all the tests that verify an application’s speed, robustness, reliability, and correct sizing. The gap between the number of tests executed and the number of tests passed also reflects the performance and the quality of the testing process. It is considered that more the tests passed by a software product, the better is the testing process and the product quality. However, sometimes poorly designed tests also get passed through poor quality software application. Therefore, this KPI may proved to be dangerous, if the level of tests, which are being passed are not assessed well.

If measured as a percentage, this KPI can be calculated by dividing the number of automated tests by the total number of test cases . We want our requests to hit the server as many times as possible during the performance tests. Whenever a new virtual user is added to the test, we expect the hit number per second to increase. But eventually, hit numbers will become stable after a period, as your server will not be able to respond to all of them in the same manner. Making technical presentations will be a good goal for your testers. Also, they can widen their networks and be an ambassador for your company and team.

We should modify KPIs and metrics based on our companies and their cultures. However, we have to stick with the core principles while modifying them. Thus, you can assign related courses to your team members and monitor them to finish those assigned courses.

This is the ratio between development effort and the defects in a given time period such as sprint, week, month, etc. We should focus on delivering valuable, defect-prone, high-quality, what is test performance indicator fast, secure, usable products. Try to evaluate/monitor/measure processes and products rather than individuals. Stress testing evaluates the behavior of systems facing peak activity.

What is the process for performance testing?

After the analysis, necessary actions should be taken to improve the processes where necessary. The time taken to test a product is calculated by proportioning the time spent developing it. With this measurement, it is possible to analyze the optimization of the test team and how effectively the resources are used.

Testers should be empowered to set performance criteria and goals because often the project specifications will not include a wide enough variety of performance benchmarks. When possible finding a similar application to compare to is a good way to set performance goals. Performance testing is a form of software testing that focuses on how a system running the system performs under a particular load. Different performance testing types measures according to benchmarks and standards. Performance testing gives developers the diagnostic information they need to eliminate bottlenecks.

What is the need for performance testing metrics?

Also, by reviewing the Delta Impact score for each individual feature, you can see the exact feature where you and your team made the biggest improvements. The higher the feedback prioritization score on a specific piece of feedback, the bigger the change in overall success score. When calculating Delta Impact, we compare that new, higher success score with what the score would have been if the feedback wasn’t addressed and display it as a percentage. When you’re viewing a piece of feedback that you own you’ll see a “status” element with a number of options in a drop down menu. If you’ve fixed an issue or implemented a good idea, select “fixed” or “implemented” and submit your changes.

  • Measuring Project Success With Delta Health Test Management In my last post, we discussed measuring tester engagement as a part of test health.
  • The primary goal of KPIs is to demonstrate the performance of your team’s testing process.
  • In summary, by following some KPIs, you can understand how your company is performing and make data-based decisions to be more successful.
  • You can also indicate other metrics such as the number of clothes sold, the percentage change in profits from last month, etc.
  • The objective is to identify the breaking point of an application.
  • For example, does it really matter how many hours all of your employees have worked over the last week?

Repeat the test to confirm each problem has been conclusively eliminated. To determine whether the application satisfies performance requirements . Thread counts – An applications health can be measured by the no. of threads that are running and currently active. Endurance testing – is done to make sure the software can handle the expected load over a long period of time.

Key Performance Indicators

Network bytes total per second – rate which bytes are sent and received on the interface including framing characters. Processor Usage – an amount of time processor spends executing non-idle threads. Then fine tune and test again to see if there is an improvement or decrease in performance.
