A performance testing is a process of determining the-speed and effectiveness of the computer, network, software program and device. In this process, it can involve the quantitative tests done in the lab, such as measuring the response-time and the number of “millions of instructions per second” at which the systems functions.
Types of performance testing
The Stress Testing is a performance-testing type to checks the stability of software, when the hardware resources are not-sufficient like memory, CPU, disk space etc. A stress testing is the Negative testing, where we load-the software with the large number of concurrent users and processes which can’t be handled through the system’s hardware resources. Main idea behind the stress-testing is to determine the-failure of systems & to keep an eye on, how the system-gracefully get recover back, this quality is called as recoverability. Stress testing comes under Non-Functional-Testing & it’s designed for test, the non-functional requirements of a software app.
The Load Testing is a type of performance-testing to checks the system with constantly increasing load on system until time load is reaches to its threshold-value. It is normally carried out-underneath controlled-environment in order to distinguish between the two different systems. It is also known as “Endurance Testing”& “Volume Testing”. Main purpose of the load testing is to monitor the response-time or staying the power of application, when the system is performing well under the heavy-load. The Load-testing comes under the Non-Functional-Testing and it is designed for test non-functional requirements of the software app.
The Volume testing is a non-functional-testing which refers to the testing a software app with a large amount of a data to be processed for checks the efficiency of app. The main goal of this testing is to monitor the performance of application under varying database volumes.
The Scalability Testing is a type of non-functional-tests & it is the testing of a software app for determines its capability to scale up in the terms of any of its non-functional-capability like user load supported, number of transactions, and the data volume etc. The primary aim is that; if this testing is for understand at what peak system prevent more-scaling.
The Spike testing is a subset of the Stress Testing. A spike-test is carried out to validate the-performance of characteristics, when the system under test subjected to workload-models & load-volumes that repeatedly-increase beyond the anticipated productions operations for the short periods of time.
Soak testing focuses on long time period. They determine’s; whether the system can works under a continuous-loads. During the soak tests it’s important to pay the attention for such an issue as performance in-degradation which means that response time after the long time period would be worse than the-beginning.
The component testing aims to checks the performance of any separate-component of the system such as the search function, pictures-upload, online-chats and etc.
The configuration testing is an essential test for dynamic systems. Changes made for systems configuration always needs to be tested for the understanding the effects they cause to the performance & behavior.
