Hi Oleg,

I'm sorry nobody has responded to this. I guess it means that nobody has a
clue.

Here are some thoughts...

Resharper tells us that the test can be made to work. We can't learn much
more because their code is proprietary.

Actually, NUnit itself is being consistent - unfortunately it's
consistently hanging.

How is NUnit running in your environment. Do you see NUnit creating a
separate process (nunit-agent) to run the tests under .NET 4.0? If so, it
may be worthwhile to experiment with running NUnit directly under .NET 4.0
so as to eliminate one level of inter-process communication. You can do
that by modifying the config file for nunit or nunit-console. My hypothesis
is that the scheduler may be making it appear as if NUnit's test process
has disappeared.

If that doesn't help, or if you are already running all in one process,
then I'll take a look more closely. Unfortunately, the Hpc scheduler isn't
something I've used.

Charlie

Title:
  Microsoft.Hpc.Scheduler test gets an exception

Status in NUnit V2 Test Framework:
  New

Bug description:
  I have the following test:

  using Microsoft.Hpc.Scheduler;
  using NUnit.Framework;

  namespace TestHPC
  {
      [TestFixture]
      internal class TestHpc
      {
          [TestCase("HEAD-NODE-SERVER", 9)]
          public static void AllCoresPresent(string headNode, int expectedCores)
          {
              int totalCores = 0;

              using (IScheduler scheduler = new Scheduler())
              {
                  scheduler.Connect(headNode);
                  ISchedulerCollection nodes = scheduler.GetNodeList(null, null);
                  foreach (ISchedulerNode node in nodes)
                  {
                      totalCores += node.NumberOfCores;
                  }
              }

              Assert.AreEqual(expectedCores, totalCores);
          }
      }
  }

  I am using a Visual Studio 2010 solution that has the project with
  this test build against .NET 4.0. This is the only test in the
  solution.

  If I use NUnit 2.6.0 GUI or console runner, the test hangs in the
  middle.

  If I use ReSharper 7.1.1 Unit Test runner pointed at my local NUnit
  2.6.0 and run the test from the project compiled against 2.6.0
  nunit.framework.dll, the test passes quite quickly.

  If I switch ReSharper to run tests with build-in NUnit 2.6.2 and
  compile against 2.6.2, the test fails with this error:

  Microsoft.Hpc.Scheduler.Properties.SchedulerException : No connection could be made because the target machine actively refused it 127.0.0.1:6729

  If I use NUnit 2.6.2 GUI or console runner, the test hangs in the
  middle.

  There are no firewalls blocking port 6729 on the HPC server. All I did
  was switch the version of NUnit.

  There seems to be a difference in how ReSharper is launching NUnit
  from the way NUnit GUI and console runner work. If I did not have
  ReSharper, I would have no clue that my test could pass.

  ReSharper's behavior is observed in TeamCity when I run the test using
  NUnit runner. Looks like JetBrains have some consistency across their
  products that work better for execution of NUnit tests than native
  tools.

  I have a variety of other tests that work just fine after the switch,
  so the problem is constrained to Microsoft.Hpc.Scheduler tests (for
  now). I can provide more information if needed. Please help!
