🧪 Testing and Validation Strategy

GenDI uses layered validation:

This validation matrix aligns with the canonical Phase 6 status source in /home/runner/work/GenDI/GenDI/docs/ROTEIRO_FASE6.md (including 4.6 marked as delivered).

1️⃣ Generator behavior tests​

Projects:

  • GenDI.SourceGenerator.CoverageEnabled.Tests
  • GenDI.SourceGenerator.CoverageDisabled.Tests
  • GenDI.SourceGenerator.NoCoverageAttribute.Tests

Coverage includes:

  • ✅ generated coverage attribute behavior
  • ✅ constructor/init-property activation generation
  • ✅ ordering rules (Group, Order, name)
  • ✅ contract discovery and fallback behavior
  • ✅ registration strategy policy coverage (RegistrationMultiplicity, RegistrationEmissionStrategy)
  • ✅ OptionConfig evolution scenarios (optional key fallback and eligibility constraints)

2️⃣ Runtime integration tests​

Project:

  • GenDI.Integration.Tests

Covers realistic IServiceCollection composition, including open generic manual registrations and mixed generated/non-generated dependencies.

3️⃣ Publish compatibility tests​

Project:

  • GenDI.Phase3.Validation.Tests

Executes trim/AOT publish verification paths.

4️⃣ Platform/framework validation​

Projects:

  • GenDI.Phase6.MinimalApiValidation.App
  • GenDI.Phase6.WorkerValidation.App
  • GenDI.Phase6.BlazorWasmValidation.App
  • GenDI.Phase6.PlatformValidation.Tests

Covers:

  • ✅ Minimal API publish validation
  • ✅ Worker Service publish validation
  • ✅ Blazor WebAssembly publish validation
  • ✅ F# exploration proving generated AddGenDIServices() is currently unavailable in fsproj

5️⃣ Testing ergonomics (GenDI.Testing)​

Projects:

  • GenDI.Testing.Tests
  • GenDI.Testing.Example.Tests

Covers:

  • ✅ ServiceBuilder fluent helper for test-time IServiceCollection composition
  • ✅ Integration with DI abstractions descriptor helpers (TryAdd, Replace, TryAddEnumerable)
  • ✅ Real-world xUnit usage with generated AddGenDIServices and property injection
