Postman load testing tutorial12/13/2023 Real browser-based simulation: When you need to mimic real user behavior and have web applications that utilize specific dynamic web application frameworks and technologies, such as Angular, AJAX (Asynchronous JavaScript and XML), JavaScript, Flash, React, and many others. HTTP/S-based simulation: Although protocol-based simulations are considered a more traditional approach in load testing due to modern web application frameworks and technologies, protocol-level scripts are perfect for component level tests in CI/CD environments and have a low footprint on injection machines. This gives developers more time for designing, executing, and analyzing their tests.ĭepending on the specific need, use case, or technology of the system being tested, the LoadView platform can run different user simulation types, for example, HTTP/S and real browser-based simulations. LoadView manages these tedious tasks, like instantiating generators and setting up global distributed agents. Load testing can become a time-consuming process. LoadView is an on-demand, cloud-based load testing platform that determines how a site, web or mobile application, or API responds to various traffic, without the hassle of managing, investing, or maintaining any additional testing infrastructure. If application performance issues go undetected in the production environment, the cost, time, and resources involved to have to go back and try to determine where the issues lie can be steep. For example, all client-side applications should go through various tests to determine their limits and assist with improving the user experience. Knowing exactly how much your site, application, system, or API (Application Programming Interface) can handle will help identify and uncover numerous issues, like bugs and database slowdowns, well before any code is committed into your staging environment. In the past, load testing was usually only carried out towards the completion of a development project, but with the renewed focus on the Agile software development process, development teams are shifting their testing left, meaning earlier and more often in the process. What is the breaking point? When will I run out of resources?.How many transactions can we handle over a specific period?.How many simultaneous users can my website, application, or system handle?.How will the number of users affect performance?.Through the information gathered during and after load testing, developers can measure the limits and gain insight into the metrics that can help answer questions such as the following: Load testing simulates real-world scenarios on your sites, applications, and systems. So, as you can see, the importance of ensuring your applications is tested to meet performance demands cannot be overstated. Also indicated in their survey were the effects on customers and visitors, such as a decline in customer confidence, tarnished brand integrity, drop in stock price. If you consider specific industries that depend on high-volume transactions, like financial services or large online retailers, the impact could likely be more significant. Additionally, the average length of downtime was 79 minutes. A recent survey conducted by Veeam, a global leader in the backup and data management space, with over 1,500 IT professionals found that the cost of one hour of downtime for high priority applications was over $84,000. Even a few seconds of downtime can significantly impact a company’s bottom line. Poor performing sites and applications can have a negative impact on conversions, transactions, and most importantly, revenue. The definition load testing generally refers to testing as a subset of the software performance testing process, which typically also includes several other types of tests, such as stress testing, soak testing, spike testing, endurance testing, volume testing, and scalability testing, among other types of testing.
