Mongo2Go: Can't run Mongo2Go on VSTS / Azure Devops

Currently, I’m working with Mongo2Go for unit test. But when I build my Project on VSTS and see it doesn’t work properly. You can check the following error

All of our tests have the same structure:

[Fact]
public async Task adds_modified_HistoryEntry()
{
    using (var runner = MongoDbRunner.Start())
    {
        var client = new MongoClient(runner.ConnectionString);
        var database = client.GetDatabase(Guid.NewGuid().ToString());
        // test code here
    }
}

For anyone who has found this issue recently, I can confirm that at least version 2.2.16 works, but some later versions (eg 3.1.3) do not.

Ok, but I have that error on my local machine when I’m running tests with dotnet test command. So it cannot be error for only VSTS hosted agents.

If it helps I have 100+ tests that use Mongo2Go package.

nothing special I guess:

netcoreapp2.2

deps:

Base class for every integration test:

public class MongoIntegrationTest<T> : IDisposable
{
    private readonly string _databaseName = "IntegrationTest";
    internal IMongoCollection<T> Collection;
    protected IMongoDatabase Database;
    internal MongoDbRunner Runner;

    internal void CreateConnection(string collectionName)
    {
        CreateConnection();
        Collection = Database.GetCollection<T>(collectionName);
    }

    internal void CreateConnection()
    {
        MongoConfigurator.Initialize();
        Runner = MongoDbRunner.Start();

        var client = new MongoClient(Runner.ConnectionString);
        Database = client.GetDatabase(_databaseName);
    }

    internal void SeedCollection(string collection, string fileName)
    {
        var path = AppContext.BaseDirectory + "../../../../DatabaseSeeds/" + fileName;
        Runner.Import(_databaseName, collection, path, true);
    }

    internal void SetMongoConnection(AutoMock mock)
    {
        mock.Provide(Database);    
    }

    public void Dispose()
    {
        Runner?.Dispose();
    }
}

and example test class:

public class CommentRepositoryTests : MongoIntegrationTest<Comment>
{
    
    [Fact]
    public async Task it_should_be_possible_to_add_and_retrieve_comment()
    {
        CreateConnection(TestConstants.CommentsCollectionName);
        var comment = TestComments.One;
        
        using (var mock = AutoMock.GetLoose())
        {
            SetMongoConnection(mock);
            var repo = mock.Create<CommentRepository>();
            
            await repo.AddAsync(comment);
            var foundComment = await repo.GetOrFailAsync(comment.Id);
            
            foundComment.Should().BeEquivalentTo(comment);
        }
        Runner.Dispose();
    }  
}

task configuration on azure devops:

task: DotNetCoreCLI@2
    displayName: Test
    inputs:
      command: test
      projects: '**/*Tests/*.csproj'
      arguments: '--configuration $(BuildConfiguration) /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:Exclude="[xunit.*]*"'

I’m going to close this issue and declare that Mongo2Go is NOT compatible with VSTS / Azure DevOps. see https://stackoverflow.com/a/44662712

If you’re using the hosted agent, you can’t open up ports or change anything about the machine’s configuration. You’ll need to set up your own agent for builds

Mongo2Go must open ports. If this is not possible, then there is absolutely no chance that we will get this up and running.

Should that example have a static field? It seems odd to dispose of a static field in a subclass’s instance method.

I think the problem may be related with .net core. Try to run them against net461. See: https://github.com/Mongo2Go/Mongo2Go/issues/48

@ppumkin It’s time to clone the repo and debug this! 😉

JohannesHoppe on Oct 12, 2018

Sorry for the misinformation. We have the same problem on VSTS agents hosted on Windows and Ubuntu, and also on local machines. The same exception in all cases.

galczo5 on Sep 13, 2018

No, Mac (#43) and Linux (#47) works now super fine. I tested both successfully.

I have absolutely no clue what happens on VSTS and really hope some user figures out what’s wrong. Unfortunately VSTS is pretty 💩, because you can’t even login to the agent… Also, time is rare here, too. 😞
