Summary

  • add Flyweight generator scenarios for no-TryGet output, duplicate factories, cache name conflicts, and invalid factory signatures
  • add Composite generator scenarios for abstract-class contracts, custom generated names, ignored properties, unsupported events, and name conflicts
  • fix Composite abstract-class contract generation so generated abstract bases override inherited abstract properties

Refs #413

Verification

  • dotnet test test\PatternKit.Generators.Tests\PatternKit.Generators.Tests.csproj --configuration Release -p:TestTfmsInParallel=false --filter "FullyQualifiedNameFlyweightGeneratorTests|FullyQualifiedNameCompositeGeneratorTests"
