LoadGen WebTesting: A Technical Perspective for Windows and Linux Core Agents

The landscape of application performance testing has experienced a significant shift with the release of LoadGen's Load & Performance WebTesting feature in Q2-2023. LoadGen has revolutionized web testing by introducing a feature that focuses on user perspective testing and provides an efficient, robust platform for conducting it. This latest addition has sparked considerable interest in the user community, from system administrators to DevOps engineers, who are keen to explore its capabilities. Here, we delve into this feature from a technical perspective, focusing on Linux and Windows Core Agents.


LoadGen WebTesting: A User-Centric Approach


LoadGen WebTesting was developed with an emphasis on user-centric testing. It is compatible with popular browsers such as Chrome, Chromium, Microsoft Edge, Firefox, and from Q3-2023, it will also support Webkit. This makes it an incredibly versatile tool for any testing scenario or environment.


User interactions like clicks, typing, and other browser page actions can be recorded and converted into actionable data and validations. This method allows for more accurate emulation of real-world user activity on your applications and offers a tangible insight into the user experience.


Moreover, LoadGen WebTesting supports using variables and data sources, making it easy to input data into your SAAS applications. It also offers the capability to measure the waiting time associated with specific user actions, a vital metric in assessing user experience and application performance.


Building Flows with LoadGen WebTesting


In LoadGen terminology, a 'Flow' or 'Workload' is a sequence of user actions that you wish to simulate and monitor. This could be a series of clicks, page navigations, data entries, or any other interactions a user might have with a web application.


With LoadGen WebTesting, users can create new Flows, link to existing ones, and edit, or remove unnecessary ones. This flexibility makes it an ideal tool for both complex and straightforward testing scenarios, from logging into a site, navigating through pages, and completing forms to performing transactions. The tool's built-in editor allows for easy modification of flows, facilitating an agile and efficient testing process.


Supporting a Multi-user Environment


LoadGen WebTesting offers comprehensive support for multi-user environments. It facilitates the configuration of test users, who simulate real user behavior and interactions with your web application. These test users help to provide a realistic picture of how your application behaves under different user loads and interaction patterns.


Test users can be manually added or imported from a CSV file, which can save time when dealing with large numbers of users. Furthermore, these test users can be linked to specific website users based on the data sources within your workload, allowing for more granular analysis of performance data.


Harnessing LoadGen Core Agents


In web testing, the LoadGen Core Agent acts as the browser launcher. It initiates the designated browser as defined in the LoadGen Application, and the sessions are carried out within the context of the selected user profile. This simulation and control of activities as if they were being performed by actual users allow the LoadGen Core Agent to offer an incredibly realistic testing environment.


Conclusion


With its focus on user-centric testing and versatility, LoadGen WebTesting is a robust, efficient platform for web application testing. Whether you're operating from Linux or Windows, LoadGen WebTesting is designed to provide you with a realistic, reliable, and powerful testing tool to ensure your applications perform at their best. This latest feature from LoadGen signifies a remarkable step forward in the realm of web testing, promising improved performance and enhanced user experience.
