DataPointProviders (NUnit 2.5)

Purpose

DataPointProviders are used to supply data for an individual parameter of a parameterized test method.

Extension Point

Addins use the host to access this extension point by name: 

	IExtensionPoint listeners = host.GetExtensionPoint( "DataPointProviders" );

Interface

The extension object passed to Install must implement the IDataPointProvider interface: 

	public interface IDataPointProvider
	{
		bool HasDataFor( ParameterInfo parameter );
		IEnumerable GetDataFor( ParameterInfo parameter );
	}

The HasDataFor method should return true if the provider is able to supply data for the specified parameter. If a provider only wants to be used on certain types of tests, it can examine the supplied ParameterInfo and its associated MethodInfo and Type.

The GetDataFor method should return a list of individual values to use for the supplied parameter in running the test.
