Run NUnit tests from Performance Center

This topic describes how to create and run NUnit tests from Performance Center.


  • The same version of NUnit Framework must be installed on the load generator and on the machine used for test creation (the one installed as NuGet package). If the versions are different, errors might occur during the test run.

  • Make sure that nunit.framework.dll resides in the same directory as the NUnit test.

  • Create an NUnit test, and save it on your file system.

    Note: You will need to convert the test to a VuGen script before uploading it to Performance Center. Use the VuGen Script Converter to convert it to a Unit Test for .NET LoadRunner script (described in Run the test from Performance Center below).

Develop an NUnit test using Visual Studio

Develop the NUnit test in Visual Studio using the LoadRunner Add-in for Developers. This requires:

  1. Installing the IDE for Dev add-in for your Microsoft Visual Studio version.

  2. Adding the LoadRunner API functions to your test.

For details, see Develop a Unit Test Using Visual Studio (NUnit test) in the LoadRunner Help Center.

    1. From the Performance Center navigation toolbar, click and select Test Management.

    2. In the test management tree, select a folder in which you want to upload the script, and click the Upload Scripts button.

    3. Select the zip file created by the converter utility, and click Upload.

    For details, see Upload scripts.

  4. Create a test using the script.

    Assign as the load generator a machine that has NUnit and the relevant prerequisites installed on it.

    For details, see Design a performance test.

  5. Run the test.
