Params should provide the ability to use an IEnumerable (á la xUnit Theories) about benchmarkdotnet HOT 4 CLOSED

yeah, I need to give [Params] a bit more love, it's too basic at the moment, but I just wanted to get something out there.

I agree, do you mean something like this:

[Params(typeof(ParamsData))]
public int Size = 1;

public class ParamsData : IEnumerable<int>
{
    public IEnumerator<int> GetEnumerator()
    {
        // Create the IEnumerable<int> however you want
    }

    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
    {
        return this.GetEnumerator();
    }    
}

also I was thinking of adding this, what do you think?

[ParamsWithSteps(start: 1, end: 1000, step: 10)]
public int Size = 1;

which would basically do the following:

for (int i = 1, i <= 1000; i += 10)
{
    // run benchmark with Size = i
}

from benchmarkdotnet.

I would go with a simplier interface with a method that returns IEnumerable<T> but yeah, that's the idea.

With ParamsWithSteps I would go further and support inheritance and provide a few examples like:

[ParamsWithStep(start: 1, end: 1000, step: 10, inclusive: true)
[ParamsQuadratic(start: 1, end: 1000, inclusive: false)
[ParamsPowerOf(start: 1, end: 1024, power: 2, inclusive: true)

Yeah I agree, I've just seen that XUnit simplified everything, so you can now support method/fields or classes via [MemberData(..)], see https://xunit.codeplex.com/SourceControl/changeset/628af664e521543c2c9d712b45d0d870f2a84d26

With ParamsWithSteps I would go further and support inheritance and provide a few examples like:

Nice idea, I'd not thought about Quadratic/PowerOf

It will be tracked as part of #256
