GM.Testing

Shared testing utilities for the GM.* ecosystem — the dependency-light core. Typed HttpClient/HttpResponseMessage assertion helpers that combine a status-code check and body deserialization in one call (ShouldBeOkAsync<T>, ShouldHaveStatus, ...), for terse, readable API integration tests. No GM runtime dependencies, so it's safe to reference from any test project. The heavier helpers live in sibling packages: GM.Testing.AspNetCore (WebApplicationFactory base), GM.Testing.Fakes (in-memory GM abstraction doubles), GM.Testing.Messaging (published-event capture), GM.Testing.EntityFramework (ephemeral DB fixtures). Test-only (DevelopmentDependency).
