NUnit 2

Load NUnit Addins

If support of NUnit 2x is selected above and you need to use NUnit addins for this bundled version, put the addins in the lib\ReSharperHost\NUnit2\addins subfolder of the JetBrains Rider installation directory (which is shown for your convenience) and choose how to load them.

Starting from NUnit 3, current directory is not set by the NUnit framework (see this answer in the NUnit tracker). JetBrains Rider sets the current directory to the temp folder by default, but you can change it.

These pairs will work the same as TestRunParameters defined in the .runsettings file:

<?xml version="1.0" encoding="utf-8" ?> <RunSettings> <TestRunParameters> <Parameter name ="param1" value="value1" /> </TestRunParameters> </RunSettings>
