LoadRunner Developer and DevWeb overview

This topic provides an overview of LoadRunner Developer capabilities and DevWeb technology.

Tip: Check out the blogs.

DevWeb technology

DevWeb is the engine of the new load testing protocol for the LoadRunner family. It focuses on communication at the HTTP transport level and over WebSockets, enabling testing against the latest web technologies (HTTP, HTTPs, HTTP/2, WebSockets).

The DevWeb technology is shared across the LoadRunner family, enabling both developers and PCoE to create and share performance test assets, using the same language. This facilitates productive collaboration between PCoE and R&D, saving time and effort.

About LoadRunner Developer

LoadRunner Developer is a lightweight tool and cross-platform solution for web testing, powered by the DevWeb engine. It was created with a developer mindset, to provide developers, performance engineers, and ops engineers with maximum flexibility.

Providing a fully integrated developer flow, LoadRunner Developer supports the shift-left needs of performance testing. As a developer, you can add performance testing to your day-to-day tasks, and script and run tests without leaving the developer ecosystem.

LoadRunner Developer can be used on any platform (Windows, Linux, macOS), and across any IDE. When creating DevWeb scripts (which are pure JavaScript), you can record, script, and execute load tests in your favorite IDE, as part of your continuous testing process. LoadRunner Developer can also be easily integrated with any CI/CD tool.

Using the modern JavaScript SDK, you can reduce scripting time, and have simple and intuitive control of your scripts. You can reuse code from the application, with the ability for native string manipulation, and native asynchronous pattern handling.

DevWeb scripts and the LoadRunner family

A DevWeb script can be created by a developer using LoadRunner Developer, or by a performance engineer in the LoadRunner VuGen scripting environment. In VuGen, DevWeb is a fully integrated, out-of-the-box protocol, benefiting from the same scripting features used for other VuGen protocol scripts.

The DevWeb script can then be shared and run natively on any of the LoadRunner family tools: LoadRunner Professional, LoadRunner Enterprise, LoadRunner Cloud, and LoadRunner Developer. In this way, DevWeb connects all project stakeholders at different testing stages to the continuous performance testing process.

In LoadRunner Developer, you can use your DevWeb script to run load tests for up to 50 virtual users (Vusers). On other LoadRunner family tools, you can scale up to the web license capacity to perform large scale tests.
