Popularly known as “Perf Testing”, Performance Testing is a subset of performance engineering. It is a type of testing that is executed to ensure that the performance of a software application is suitable and perfect under the expected workload. It is the process of determining the speed, effectiveness, reliability, scalability, and other important features and elements of the system. Moreover, performance testing can be used to compare two or more applications to compare their system speed, data transfer rate, bandwidth, efficiency and reliability.
During the process of performance testing, the system is tested under a mixture of load conditions, where the required response time is tested by the system under varying workloads. Furthermore, software performance testing involves the testing of application under test to ensure that application is working as expected under variety of load conditions. The goal of performance testing is not only find the bugs in the system but also to eliminate the performance bottlenecks from the system.
Excellent performance and unique features are two elements of a software application that attract users and new customers. However, to ensure this brilliance and exceptional performance of a software system, software engineers use a variety of performance testing techniques. All these types of performance tests cater to various testing requirements of the developer, tester, and the client, while making sure that each and every phase of the software development process is tested properly. Moreover, with the assistance of these tests one can monitor, detect and resolve all the defects in a software and validate its quality.
The importance of a well performing application and system is immensely high in the software industry. A well performing application lets the end users carry out a variety of given tasks without any unwarranted delay or irritation. Additionally, with an application that has excellent performance, one can easily browse a website and find whatever they are looking for without experiencing several issues and difficulties. It is only through performance testing that these elements and features of a software are validated and maintained, which further improves the performance of the application as well as its functionality, effectiveness and quality. Other reasons that make performance testing important are as follows:
The process of performance testing revolves around the quality and effectiveness of application and software’s scalability, speed and stability. Throughout the execution of testing, each of these elements of the software are monitored, which makes sure that the application or the software performs properly. However, while executing performance testing developers and testers come across various issues and discrepancies, which makes the whole process time consuming and difficult. Hence, here is a list of some common issues found during the process of testing the performance of an application.
The process of software testing plays a crucial role in software testing life cycle. It is one such process that ensures that the software functions and performs effectively in a various conditions and under huge load. Performance testing is done to make sure an app runs fast enough to keep a user's attention and interest. Moreover, one can find a vast variety of performance testing tools in the market that cater to all the testing needs of the client and the end user. Below is a comprehensive list of most popular performance testing tools used by software testers to test the performance as well as the quality of a software application.
An essential part of software testing life cycle, performance testing is important for the success of a software application. It is a type of software testing, which makes certain that the application is developed as per the customer satisfaction and prevents the risk of product failure. Performance Testing is done to provide stakeholders with information about their application regarding speed, stability and scalability. More importantly, it uncovers what needs to be improved before the product is delivered to the client or for use to the end user. Without Performance Testing, software is likely to suffer from issues such as, running slow while several users use it simultaneously, inconsistencies across different operating systems and poor usability. Performance testing encompasses a wide range of different tests, which enable analysis of various aspects of the system. In short, the purpose of performance testing is to provide its investors and stakeholders a high level of confidence in their web application’s ability to handle large volumes of traffic, prior to the products go live.
