Proyect IntegrationTests

[adelaserna82]

Hello,

first of all, thank you very much for creating a template with this type of software architecture.
I downloaded the template and everything works great, but there's a problem in the integration test project with the Testing class.
The Startup class doesn't exist in the API. I understand that when you migrated it from .NET 6.0 to 7.0, this issue might have been left pending.
This is the file location: VerticalSliceArchitecture/tests/Application.IntegrationTests/Testing.cs

Thanks
