![]() In addition, changes should not be made to the testing environments between tests. Organizations should find testing tools that can best automate their performance testing process. After any fine-tuning, retest to see if there is an increase or decrease in performance. ![]() Arrange resources to prepare the test environment, then begin to implement it. Configuring and implementing test design environment.Build test cases around performance metrics. This should include performance goals and constraints for metrics. Identifying and defining acceptable performance criteria.This includes test and production environments as well as the testing tools. ![]() However, a generic process may look like: How to conduct performance testingīecause performance testing can be conducted with different types of metrics, the actual process can vary greatly. These metrics and others help an organization perform multiple types of performance tests. The number of hardware interrupts a process receives per second The volume of data per second that can move between workloads, usually across a network The amount of time that elapses between a user-entered request and the start of a system's response to that request The working storage space available to a processor or workload How many units of information a system processes over a specified time Performance testing metricsĪ number of performance metrics, or key performance indicators ( KPIs), can help an organization evaluate current performance. The process can be used to compare two or more devices or programs. Performance testing can also verify that a system meets the specifications claimed by its manufacturer or vendor. This form of testing also can be used to ensure an organization is prepared for a predictable major event, for online stores. Performance testing can be used as a form of software testing to help identify the nature or location of a software-related performance problem by highlighting where an application might fail or lag. Slow data transfer rates might be inherent in hardware but could also result from software-related problems - such as too many applications running at the same time or a corrupted file in a web browser. For example, even the fastest computer will function poorly on the web if the bandwidth is less than 1 megabit per second ( Mbps). Bottlenecks are a single point or component within a system's overall function that holds back overall performance. Why use performance testing?Īn organization can use performance testing as a diagnostic aid to locate computing or communications bottlenecks within a system. If the response times are so slow that it would annoy end users, then this means it should be tested to find where the bottleneck is. As an example, an organization can measure the response time of a program when a user requests an action the same can be done at scale. Typical parameters include processing speed, data transfer rates, network bandwidth and throughput, workload efficiency and reliability. Performance requirements should be identified and tested. Performance testing can involve quantitative tests done in a lab, or in some scenarios, occur in the production environment. Determining if the developed system meets speed, responsiveness and stability requirements while under workloads will help ensure a more positive user experience. Without some form of performance testing in place, system performance will likely be affected with slow response times, experiences that are inconsistent between users and the operating system, creating an overall poor user experience. Organizations will run performance tests in order to identify performance-related bottlenecks. Performance testing is a testing measure that evaluates the speed, responsiveness and stability of a computer, network, software program or device under a workload.
