Datapoint(s)Attribute should work on IEnumerable<T> as well as on Arrays

[Charlie Poole]

[Copied from a thread on the nunit-discuss list]

I am currently playing around with NUnit's concept of theories /
datapoints.
I want to use lists as parameter for a certain Theory(test).

My code is structured like this:

//Preparation of data

 public static List<MySpecialEnum> PrepareList()
 {
           List<MySpecialEnum> settings = new List<MySpecialEnum>();
           foreach (MySpecialEnum setting in
Enum.GetValues(typeof(MySpecialEnum)))
           {
                   settings.Add(setting);
           }
           return settings;
 }

//prepare datapoints
[Datapoints]
 public static List<MySpecialEnum> settingValues = PrepareList();

//create theory
[Theory]
public void CTATheorySample(MySpecialEnum settingVal)
{
 Assume.That(/*everything is okay with settingVal */);
}

When I try to execute the tests, no parameter is visualised in the
NUnit UI and the error "no arguments were provided" is shown in the
NUnit "errors and failures" window!
Do you have any hints or workarounds for me ??
By the way I am using NUnit 2.5.3

Best regards and thanks for any hints,

Bernie

The problem with the above is that the DatapointsAttribute is only recognized on an array. It should be extended to allow any
object implementing IEnumerable<T> where T is the type of the argument. Changing the the title to reflect this.
