How can we run a test method with multiple parameters in MSTest?

EDIT 4: Looks like this is completed in MSTest V2 June 17, 2016: https://blogs.msdn.microsoft.com/visualstudioalm/2016/06/17/taking-the-mstest-framework-forward-with-mstest-v2/

Original Answer:

As of about a week ago in Visual Studio 2012 Update 1 something similar is now possible:

[DataTestMethod]
[DataRow(12,3,4)]
[DataRow(12,2,6)]
[DataRow(12,4,3)]
public void DivideTest(int n, int d, int q)
{
  Assert.AreEqual( q, n / d );
}

EDIT: It appears this is only available within the unit testing project for WinRT/Metro. Bummer

EDIT 2: The following is the metadata found using "Go To Definition" within Visual Studio:

#region Assembly Microsoft.VisualStudio.TestPlatform.UnitTestFramework.dll, v11.0.0.0
// C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0\ExtensionSDKs\MSTestFramework\11.0\References\CommonConfiguration\neutral\Microsoft.VisualStudio.TestPlatform.UnitTestFramework.dll
#endregion

using System;

namespace Microsoft.VisualStudio.TestPlatform.UnitTestFramework
{
    [AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
    public class DataTestMethodAttribute : TestMethodAttribute
    {
        public DataTestMethodAttribute();

        public override TestResult[] Execute(ITestMethod testMethod);
    }
}

EDIT 3: This issue was brought up in Visual Studio's UserVoice forums. Last Update states:

This feature is in pre-release now and works with Visual Studio 2015.

For example:

[TestClass]
public class UnitTest1
{
    [TestMethod]
    [DataRow(1, 2, 2)]
    [DataRow(2, 3, 5)]
    [DataRow(3, 5, 8)]
    public void AdditionTest(int a, int b, int result)
    {
        Assert.AreEqual(result, a + b);
    }
}
