Running tests from a remote folder expressed as a UNC path has never
actually been supported by NUnit - even if it seemed to be working in
2.5.10. The standard approach is to assign a file letter to the remote
share and use that in the path to the test assembly.

However, I'll look at the change and see if we can put back the
functionality that was working for you. For NUnit 3.0, we'll examine the
possibility of officially supporting UNC paths.

Title:
  Test loaded from remote folder failed to run with exception
  System.IODirectory Not Found .

Status in NUnit V2 Test Framework:
  New

Bug description:
  When we load test from remote machine folder as
  \\MachineName\TestFolderName project loads successfully.But when I
  tried to run same tests it throws exception as follow

  System.IODirectory Not Found :Could Not Found Part of the Path
  'D:\NUnitProject\bin\Debug\MachineName\TestFolderName'.

  Above scenario was working fine in  NUnit-2.5.10.11092. When I tried to find out cause of this issue ,I find that there are changes in
  NUnit.Core.AssemblyHelper class.Differnces between these two versions are as follow

  NUnit-2.5.10.11092

   public static string GetAssemblyPath(Type type)
  {
       return GetAssemblyPath(type.Assembly);
  }

  public static string GetAssemblyPath(Assembly assembly)
  {
   string path = assembly.CodeBase;
   Uri uri = new Uri(path);

   // If it wasn't loaded locally, use the Location
   if (!uri.IsFile)
   return assembly.Location;

   if (uri.IsUnc)
   return path.Substring(Uri.UriSchemeFile.Length + 1);

   return uri.LocalPath;
  }

  public static string GetDirectoryName( Assembly assembly )
  {
     return System.IO.Path.GetDirectoryName(GetAssemblyPath(assembly));
  }
          



  
  Whereas the code in NUnit version 2.6 is as follow


  #region GetAssemblyPath

          public static string GetAssemblyPath(Type type)
          {
              return GetAssemblyPath(type.Assembly);
          }

          public static string GetAssemblyPath(Assembly assembly)
          {
                string uri = assembly.CodeBase;

                if (IsFileUri(uri))
                   return GetAssemblyPathFromFileUri(uri);
                else
                   return assembly.Location;
           }

          #endregion

          #region

          // Public for testing purposes
          public static string GetAssemblyPathFromFileUri(string uri)
          {
              // Skip over the file://
              int start = Uri.UriSchemeFile.Length + Uri.SchemeDelimiter.Length;

              if (System.IO.Path.DirectorySeparatorChar == '\\')
              {
                  // Handle Windows Drive specifications
                  if (uri[start] == '/' && uri[start + 2] == ':')
                      ++start;
              }
              else
              {
                  // Assume all Linux paths are absolute
                  if (uri[start] != '/')
                      --start;
              }

              return uri.Substring(start);
          }

          {

          }
