XLT

XLT is an extensive load and performance test tool developed and maintained by Xceptance. If you need more information, here is the current website and the current documentation portal.

The documentation was fully rewritten in 2020 and it is continuously updated. We appreciate your feedback. You can also directly contribute on GitHub at https://github.com/Xceptance/xlt-documentation. If you need any information from the legacy documentation, you can still find it at https://lab.xceptance.de/releases/xlt/5.7.1/index.html

Open Source

XLT has been open sourced on 30 January 2020 under the Apache License 2.0.

How to Build XLT

The XLT build process is based on the Apache Ant build tool. The build works best when being run on a Linux machine.

Required Tools

• Latest JDK 11
• Latest Apache Ant
• Chrome or Chromium browser (to package the timer-recorder extension for Chrome/Chromium)
• Node.js in version 16.15.1 (to bundle the resultbrowser)
• Optional tools:
  • Only if you want to run the XLT unit tests:
    • chromedriver
    • geckodriver

IDE Import

Follow your IDE's instructions for importing an existing Maven project.

Once the project import is complete, a module package conflict may be reported. In this case, go to your IDE's build path settings and remove the jdk.jsobject module from the module dependencies.

Example - Eclipse IDE

• Right-click on imported project and select Build Path > Configure Build Path...
• In right hand view select tab Module Dependencies
• In All Modules list lookup jdk.sobject
• Mark and remove it

Build Steps

To create the XLT distribution archive xlt-X.Y.Z.zip, run the following command. If all went well, the archive can then be found in folder target/dist.

ant clean dist

To perform a release build which requires all unit tests to pass, run this command:

ant clean release 

Limitations

When you build XLT by yourself, the following limitations apply.

• The timer-recorder extension for Firefox is not signed yet. Hence, when using XltFirefoxDriver later on, Firefox will refuse to install that extension. If you need the extension, download the official XLT distribution which contains a correctly signed extension.

Building on Windows or macOS

• Some unit tests are known to fail on Windows.
• You will need to adjust the path to Chrome/Chromium in build.properties according to your system.

Building on Linux

• Depending on the distribution you use, you might need to adjust the path to your Chrome/Chromium executable in build.properties on Linux as well.
