Factors controlling the Performance Testing | Software Testing

  • Last Updated : 19 Oct, 2021

Prerequisite : Performance Testing | Software Testing

Performance Testing is conducted to discover the response time, throughput, etc., and also to execute its required functions by doing a comparison with different versions of the same product or different competitive products. It is a type of software testing that ensures that software applications perform correctly under their expected workload. It is a testing technique carried out to determine system performance in terms of sensitivity, reactivity, and stability under a particular workload.

The factors controlling the performance testing are given below :

  1. Throughput –
    The throughput is a concept of determining how well a software or an application can perform. It is a capability of the system or the product handling multiple transactions that are determined by a factor. It also represents the number of requests or business transactions processed by the software or an application in the specified time frame. Note that the throughput, i.e., the number of transactions serviced by the product per unit time varies according to the load the product is put under.
     
  2. Response Time –
    The response time is defined as the delay between the point of request and the first response from the software product. In a normal client-server environment, a throughput determines the number of transactions that can be handled by the server whereas a response time defines the delay between the request and response of an application.
     
  3. Latency –
    The latency can be defined as the delay caused by an application, OS, and by the environment that are calculated separately. Note that, not all the delay that happens between the request and the response is caused due to the product. In the networking scenario, the network or other products which are sharing the network resources can cause delays. Therefore, we must know that what delays the application causes and what delays the environment causes.
     
  4. Tuning –
    Tuning is a process in which the product’s performance is improved by adding some different values to the parameters (variables) of the application, operating system, and other components. It enhances the product’s performance without modifying the source code of the product and here each product may have certain parameters that can be added at run time to get a great performance.
     
  5. Benchmarking –
    Benchmarking can be defined as the process of comparing the throughput and response time of the product to those of the competitive products. Here, no two products are the same in features, cost, and functionality. Therefore, it is not easy to decide that what two or more parameters must be compared between the two products.
     
  6. Capacity Planning –
    Capacity planning is a process in which we determine what type of hardware and software resources are needed for running an application with a given user load. Here, the most significant factor that affects performance testing is the availability of resources. The right kind of hardware and software configuration is needed to derive the best results from performance testing and for deployments.
