RavenDB4 Exception when batch running tests

[Lokesh]

Hi,

I am using RavenDB4 and RavenTestDriver. When running unit test cases as a batch or mostly run all, random test case(s) are randomly failing with the following exception:

1. Raven.Client.Exceptions.AllTopologyNodesDownException

There are no nodes in the topology at all

   at Raven.Client.Http.NodeSelector.UnlikelyEveryoneFaultedChoice(NodeSelectorState state)

2. Raven.Client.Exceptions.Database.DatabaseDoesNotExistException

   at Raven.Client.Documents.Session.DocumentSession.Load[T](String id)

   at Flucticiel.Simetryk.Extensions.Common.Context.ExtensionContext.Set(IDocumentSession session, String tenantName)

The above exceptions are actually inner exception that happen at the same place during bootstrapping (which is the 1st load statement from session object). What makes me even more curious is that it is able to open a session but when I try to load a document, it throws the above exceptions.

Is this something that is caused due to wrong initialization of the TestDriver? Do you have any suggestion on how to fix or work around this?

Thanks,

Lokesh

Hi,

1) What version of Raven.Client and Raven.Server are you using?

2) Can you show us your implementation of RavenServerLocator and a sample test?

Thanks,

Arek

Hi Arkadiusz,

Thanks for the reply.

1. The client I am using is 4.0.3-patch-40034 and the server is 4.0.3-patch-40034.

2. Following is the implementation of RavenServerLocator:

public class TestRavenDBLocator : RavenServerLocator

    {

        private string _serverPath;

        private string _command = "dotnet";

        private readonly string RavenServerName = "Raven.Server";

        private string _arguments;

        public override string ServerPath

        {

            get

            {

                if (!string.IsNullOrEmpty(_serverPath))

                {

                    return _serverPath;

                }

                var path = Environment.GetEnvironmentVariable("Raven_Server_Test_Path");

                if (!string.IsNullOrEmpty(path))

                {

                    if (InitializeFromPath(path))

                        return _serverPath;

                }

                

                //If we got here we didn't have ENV:RavenServerTestPath setup for us maybe this is a CI enviroement

                path = Environment.GetEnvironmentVariable("Raven_Server_CI_Path");

                if (!string.IsNullOrEmpty(path))

                {

                    if (InitializeFromPath(path))

                        return _serverPath;

                }

                //We couldn't find Raven.Server in either enviroment variables lets look for it in the current directory

                foreach (var file in Directory.GetFiles(Environment.CurrentDirectory, $"{RavenServerName}.exe; {RavenServerName}.dll"))

                {

                    if (InitializeFromPath(file))

                        return _serverPath;

                }

                //Lets try some brut force

                foreach (var file in Directory.GetFiles(Directory.GetDirectoryRoot(Environment.CurrentDirectory), $"{RavenServerName}.exe; {RavenServerName}.dll", SearchOption.AllDirectories))

                {

                    if (InitializeFromPath(file))

                    {

                        try

                        {

                            //We don't want to override the variable if defined

                            if (string.IsNullOrEmpty(Environment.GetEnvironmentVariable("Raven_Server_Test_Path")))

                                Environment.SetEnvironmentVariable("Raven_Server_Test_Path", file);

                        }

                        //We might not have permissions to set the enviroment variable

                        catch

                        {

                        }

                        return _serverPath;

                    }

                }

                throw new FileNotFoundException($"Could not find {RavenServerName} anywhere on the device.");

            }

        }

        private bool InitializeFromPath(string path)

        {

            if (Path.GetFileNameWithoutExtension(path) != RavenServerName)

                return false;

            var ext = Path.GetExtension(path);

            if (ext == ".dll")

            {

                _serverPath = path;

                _arguments = _serverPath;

                return true;

            }

            if (ext == ".exe")

            {

                _serverPath = path;

                _command = _serverPath;

                _arguments = string.Empty;

                return true;

            }

            return false;

        }

        public override string Command => _command;

        public override string CommandArguments => _arguments;

    }

I have the environment variable set up to point to RavenDB4 server dll. I don't really have a sample test for this as it fails randomly when all tests are run in a batch.

I am wondering if there is a way to wait and ensure that the database is created after the CreateDatabaseOperation?

Thanks,

 Lokesh

Can you show us any sample test you have? It seems something deletes your db behind your back. Are you creating a db per test case?

store.Maintenance.Server.Send(new CreateDatabaseOperation(new DatabaseRecord("MyNewDatabase")));

is sync operation. Once the following command returns the db is created.

Hi Arkadiusz,

I am sorry, but I think its an issue on our part. Some static property.

Thanks a lot. Sorry again for the trouble.

Regards,

Lokesh
