This was corrected with the 2.5.2 release but the older docs on the web
site had not been updated.

Status in NUnit V2 Test Framework: Fix Released
Bug description:
http://nunit.org/index.php?p=testCaseSource&r=2.5 says:
instances from a data source in a separately defined class.
[TestFixture]
public class MyTests
{
[Test,TestCaseSource(typeof(MyFactoryClass),"TestCases")]
public void DivideTest(int n, int d)
{
return n/d;
}
...
}
public class MyFactoryClass
{
public static IEnumerable TestCases
{
get
{
yield return new TestCaseData( 12, 3 ).Returns( 4 );
yield return new TestCaseData( 12, 2 ).Returns( 6 );
yield return new TestCaseData( 12, 4 ).Returns( 3 );
yield return new TestCaseData( 0, 0 )
.Throws(typeof(DivideByZeroException))
.SetName("DivideByZero")
.SetDescription("An exception is expected");
}
}
}
Note that this code will not work, because for the .Returns method to work the
testcase must actually return something. In this example the test case returns
void.
To fix:
change:
public void DivideTest(int n, int d)
to read:
public int DivideTest(int n, int d)
