LevelOfParallelism Attribute

This is an assembly-level attribute, which may be used to specify the level of parallelism, that is, the maximum number of worker threads executing tests in the assembly. It may be overridden using a command-line option in the console runner.

This attribute is optional. If it is not specified, NUnit uses the processor count or 2, whichever is greater. For example, on a four processor machine the default value is 4.

Example

The following code, which might be placed in AssemblyInfo.cs, sets the level of parallelism to 3:

  [assembly:LevelOfParallelism(3)]
