Hi everyone 🙂,
I am trying to write integration with Aspire and following the article on https://learn.microsoft.com/en-us/dotnet/aspire/fundamentals/testing.

The DistributedApplicationTestingBuilder wraps the DistributedApplicationBuilder of the Aspire app host. This allows to spin up the orchestrator before running the tests.

I slightly changed the configuration of the orchestrator to use secrets for some of the required credentials. I don't want to have them in the code and visible on my GitHub repositories.

The plan is to use the .NET Secret Manager to inject them for my development environment and Azure KeyVault or any other type of server ingestion mechanism in the production environments.

The DistributedApplicationTestingBuilder doesn't allow to modify the configuration.

The simple solution is for the test environment to inject the same environment variables.

I was wondering if there is a way to modify the configuration before building the host:

 var appHost = await DistributedApplicationTestingBuilder.CreateAsync<Projects.MyProjectReference>();
 // Modify configuration
await using var app = await appHost.BuildAsync();

Is there a way for the test runner to launch a different profile for the Aspire app host?

Thanks in advance 🙂
