How already answered, you should decouple your system

public class NugetPlatformModel
  {
    public bool IsHavingLicense { get; set; }
    public List PlatformProduct = new List();
    public NugetPlatformModel(IPlatformProductProvider provider)
    {
      var xmldoc = new XmlDocument();
      //System.Web.HttpContext.Current.Server.MapPath(@"~\Content\PlatformProducts.xml")
      xmldoc.Load(provider.Filepath);
    }

    public interface IPlatformProductProvider
    {
      string Filepath { get; }
    }

    public class PlatformProductProvider: IPlatformProductProvider
    {
      string _filepath;
      public string Filepath
      {
        get { return _filepath; }
        set { _filepath = value;}
      }

      public PlatformProductProvider(string path)
      {
        _filepath = path;
      }
    }

  }

And your test could be:

[Test]
    public void Account_UnlicensedCustomerIdentity_IsStudioLicenseAndIshavinglicenseFalse()
    {
      //Arrange
      // using Moq
      //var mock = new Mock();
      //IPlatformProductProvider provider = mock.Object;
      //provider.Filepath = "pippo.xml";
      // otherwise
            var provider = new PlatformProductProvider("pippo.xml");

      //Act
      NugetPlatformModel nugetPlatformModel = new NugetPlatformModel(provider);

      //Assert
      AssertEquals(false, nugetPlatformModel.IsHavingLicense);

    }
