.NET 6 Minimal APIs: Testing Strategies

Minimal APIs are great, but how do you test them without a `Startup` class?

WebApplicationFactory

You must expose the internal `Program` class to your test project.

// Program.cs
var app = builder.Build();
// ...
app.Run();

// Hack to make it visible
public partial class Program { }

Now you can use `WebApplicationFactory<Program>` in xUnit to spin up the in-memory server.
