Azure DevOps - Integration Tests failing

[lopezbertoni]

I have a very simple initial asp.net api (dotnet 9) running on top of the latest aspire (9.3).

The AppHost / Orchestrator is setup like this:

var builder = DistributedApplication.CreateBuilder(args);

var sql = builder.AddSqlServer("sqlserver")
                 .WithDataVolume();

var db = sql.AddDatabase("Ppy-Development");

// Add ASP.NET Core API and reference the database
builder.AddProject<Projects.Ppy_Host_Api>("Ppy-Host-Api")
    .WithReference(db, "SqlAzure")
    .WaitFor(db);

builder.Build().Run();

I setup some acceptance / integration tests to test one set of api resources (CRUD operations) and it works with no issues locally.

When I run it on Azure DevOps CI pipeline, all tests throw the same error:

Failed ShouldCreateBank [41 s]
Error Message:
OneTimeSetUp: System.ArgumentException : Endpoint '' for resource 'Ppy-Host-Api' not found. (Parameter 'endpointName')

Here's the code for the HostApiFactory.cs since it's failing when we try to create an http client.

internal static class HostApiFactory
{
    private const string PpyHostApiIdentifier = "Ppy-Host-Api";
    private static DistributedApplication? _app;
    private static HttpClient? _httpClient;

    public static async Task<HttpClient?> Setup()
    {
        if (_httpClient is null && _app is null)
        {
            // Setup aspire host
            var builder = await DistributedApplicationTestingBuilder.CreateAsync<Projects.Ppy_Host_Orchestrator>();
            builder.Services.ConfigureHttpClientDefaults(clientBuilder =>
            {
                clientBuilder.AddStandardResilienceHandler();
            });
            
            _app = await builder.BuildAsync();
            var resourceNotificationService = _app.Services.GetRequiredService<ResourceNotificationService>();
            await _app.StartAsync();

            _httpClient = _app.CreateHttpClient(PpyHostApiIdentifier);

            //await resourceNotificationService
            //    .WaitForResourceAsync("Ppy-Host-Api", KnownResourceStates.Running)
            //    .WaitAsync(TimeSpan.FromSeconds(30));
            using var cts = new CancellationTokenSource(TimeSpan.FromSeconds(30));
            await _app.ResourceNotifications.WaitForResourceHealthyAsync(
                    PpyHostApiIdentifier,
                    cts.Token);
        }
        return _httpClient;
    }

    public static async Task Dispose()
    {
        if (_app is not null && _httpClient is not null)
        {
            await _app.StopAsync();
            _httpClient.Dispose();
        }
    }
}

Any ideas on why this fails on Azure DevOps? Any special configuration maybe that needs to be added to Azure DevOps?

The build pipeline is running on ubuntu-latest if it helps.

Any help is appreciated. Thanks in advance!

i'm curious about this and i don't want it to happen to me

have you

• time to investigate with a local agent as per
• sanity checked the tests with a simple no-op test that has different initialization [setup] whathaveyou
• sanity checked the build agent's permissions, just in case

Hey.

Yes to all.

In the project I have 3 test assemblies.
1 that's only running unit tests - works
1 that's only running integration tests - basically tests my access layer (assembly that only talks to SQL db) and it works. For this one I'm using Test Containers.
1 that's running acceptance tests - this one fails with the mentioned error above. This one is testing the API and I'm trying to get it to work with Aspire. It works with no issues locally but fails on Azure DevOps.

Still no luck with this one.
