Minimize Downtime & Reduce the Risk of Outages And the optimal way to guarantee everything is functional is to test the web app performance over and over until the test results meet the developers’ requirements and the users’ expectations. For instance, if you are crafting an e-commerce website where online shoppers wander around and make purchases, then you have to make sure that the key functionalities, such as adding items to the cart, checkout process, and payment gateway, work perfectly. End-to-end performance testing is not a functional testing technique, but it can ensure that all the key features of a web application work properly before release by checking the app’s response time, network latency, database queries, and other important performance metrics. One of the key principles to generating web app success is to ensure its solid foundation and the performance of its basic functions. Here are some of the main objectives of performance tests: Validate the Core Functions of the Web Apps By conducting performance tests for your web apps, you are stepping closer to the target of delivering a functional product to end-users. This is where web application performance testing comes into the picture. If a web application is slow or not performing as expected, users will quickly become frustrated and may even switch to a competitor’s product. A significant part of providing an excellent user experience is ensuring that the digital product’s performance is able to meet the user’s expectations in terms of speed and responsiveness. In this nowadays competitive IT business world, every software company strives to stand out from its competitors by offering the best user experience to its customers. Why Need Web Application Performance Tests? Some of the popular performance testing tools that are commonly in use are HP LoadRunner, Apache, JMeter, NeoLoad, AppDynamics, Dynatrace Ruxit, etc. In automated testing, testers use a performance testing tool to generate a load of virtual users and analyze the system performance under that test data. When manual testing is used, testers identify key scenarios and use different testing tools to monitor the system performance under those scenarios. Web application performance testing can be done manually or using automated tools. By running web application performance tests, businesses can verify the functionalities to see which are workable and which are not, identify performance bottlenecks and optimize their web applications accordingly. In its simplest terms, web application performance testing is a subset of performance testing that is specifically designed to test web applications, which is carried out to determine how well a web-based application performs in terms of speed, web server response time, network latency, database queries, and so on. When it comes to web application development, the performance test plays a significant role in securing the overall quality of the product and ensuring that the end-users have a smooth experience while using it. What Is Web Application Performance Testing? Typically, load tests are done to check the application’s response under various conditions, whereas performance tests are carried out to verify different performance-related aspects. The load and performance testing are often mixed up with each other due to some similarities and misconceptions, but they are not interchangeable in any aspect. On the other hand, stress tests are the process of putting unexpected or peak load conditions on the application to check maximum operating capacity. Load testing tools like LoadRunner, JMeter, and NeoLoad help QA engineers simulate the expected load on the application and collect essential performance metrics. In brief, a load test is a testing process of putting the expected load on the application and measuring its response under normal circumstances. Performance testing consists of various sub-types of software testing, but the most typical ones are load testing and stress testing. In the end, the goal of successful performance testing is to measure the performance criteria, including speed, data transfer velocity, response time, resource usage, etc. When the QA teams execute performance tests, they desire to ensure that the product can work flawlessly without any error or performance issues based on the test results. This non-functional testing methodology aims to measure the overall performance of an application, system, or software in terms of responsiveness, stability, scalability, and resource usage under the normal load of a number of concurrent users. Generally, performance testing is one of the different software testing types. To clearly understand the concept of web application performance testing, you should go through the definition of performance tests first. What Is the Concept of Web Application Performance Testing?
