Random test failure on CI #7

Closed tjaskula closed 4 years ago

tjaskula commented 4 years ago

Have to investigate why some tests TestAlteredLeadership are randomly failing as here

https://ci.appveyor.com/project/VlingoNetOwner/vlingo-net-directory/builds/27992540/tests

mihaj commented 4 years ago

Here are some details of current investigation:

In DirectoryServiceTest Setup constructor the clients (client1,...) are null:

            _client1 = _testWorld.ActorFor<IDirectoryClient>(
                Definition.Has<DirectoryClientActor>(
                    Definition.Parameters(_interest1, _group, 1024, 50, 10)));

The error message I get is:

Test Name:  Vlingo.Directory.Tests.Model.DirectoryServiceTest.TestAlteredLeadership
Test Outcome:   Failed
Result Message: System.NullReferenceException : Object reference not set to an instance of an object.
Result StandardOutput:

I made two small updates and here are the build results: https://ci.appveyor.com/project/VlingoNetOwner/vlingo-net-directory/builds/28013507

tjaskula commented 4 years ago

The root cause may be: Cannot assign network interface. Maybe something with conflicting ports to check on. If the port was not released by previous test or something like that

tjaskula commented 4 years ago

The route cause of this issue is different. I'm closing this issue because it is misleading. New issue has been opened #12
