loadUI FAQ

Load Testing with loadUI

General Questions

  • Why create new software instead of adding load testing functionality in soapUI?
    In our commitment to creating Fast and Fun software we need to avoid software bloat. If we would do that it would increase the size of soapUI twofold, and we would not hold true to our spirit.
  • Why should I use loadUI?
    You should use loadUI since it’s a very easy fast and flexible performance testing tool for a number of technologies.
  • What license do you use?
    LoadUI is distributed under the EUPL license. An OSI approved, GPL compatible Open Source license. EUPL is well considered, global software license available in several languages.
  • Where do I get support?
    Support is available in our community forums. Eviware will provide commercial support with the upcoming release of loadUI Pro in early 2012.
  • Where do I give feature requests?
    We do appreciate feature requests! Please go to our Feature Request forum.

Distribution and Execution

  • How do I start loadUI?
    Easy! Download, install and run the software.
  • How do I start a loadUI agent?
    After completing the loadUI install, you can run loadUI by locating the launcher shortcuts located in the usual OS specific places (desktop, start menu, etc.), or by directly running the loadUI.bat/loadUI.sh file in the installation directory.
  • How do I distribute agents?
    Install and run the loadUI agent software on the desired machines and register them in the loadUI controller application. The software is available for Windows, Linux, and Mac.

loadUI Usage

  • How do I deploy and run tests on an Agent?
    Just drag and drop a test to the runner. Done!
  • How do I view the results of a test?
    Use the Statistics or the Table Log components. Connect them to the output of any Runner.
  • I want to do a ramp up test, how do I do it?
    There’s a component for that! Read more.
  • How many virtual users can you test?
    There are two answers to this question. First there’s the legal answer, unlike commercial tools there are not hidden limits in the software and our license does not prevent you from using any number of users. Then there’s the technical answer; in our benchmarks we have created 300 000 virtual users on one server. Since loadUI is so easy to distribute this is only a starting point for creating truly large scale Load Tests.
  • What is the level of integration between loadUI and soapUI?
    Ah! Any Functional Test in soapUI can be run as a Load Test in loadUI with just one mouse click.

Technology

  • What technology is loadUI built on?
    LoadUI uses new, but stable technologies, such as JavaFX for the interface. OSGi for componentization and Groovy scripting for component creation. loadUI also includes a powerful framework for creating your own components.
  • Can I write my own modules?
    Yes. Information can be found here. Please let us know if you want us to make the module public.
  • How do we script loadUI?
    soapUI uses Groovy for scripting. We also have a framework for extending LoadUI.
  • Is the source code available?
    Of course. We’re Open Source. The code can be retrieved from our public SVN repository.
