Summary

  • keep contract-first Facade generation faithful to the declared contract when ForceAsync is set, avoiding invalid interface implementations
  • add TinyBDD coverage for signature matching failures, task-like comparison, missing-map stubs, dependency field-name collisions, and nullable/struct generic constraints
  • raise FacadeGenerator source coverage from 96.3% to 98.0% in the generator-only report and bring local generator assembly source coverage to 95.0%

Part of #413.

Validation

  • dotnet test test\PatternKit.Generators.Tests\PatternKit.Generators.Tests.csproj --configuration Release --framework net10.0 --filter "FullyQualifiedName~FacadeGeneratorTests" --logger "console;verbosity=minimal"
  • dotnet test test\PatternKit.Generators.Tests\PatternKit.Generators.Tests.csproj --configuration Release --no-restore -p:TestTfmsInParallel=false --collect:"XPlat Code Coverage" --results-directory .\TestResults --logger "console;verbosity=minimal" -- DataCollectionRunSettings.DataCollectors.DataCollector.Configuration.Format=cobertura
  • dotnet tool run reportgenerator -reports:"TestResults*\coverage.cobertura.xml" -targetdir:"coverage-report-generators" -reporttypes:"TextSummary;Cobertura" -assemblyfilters:"+PatternKit.Generators" -filefilters:"-**/.Tests/;-/Tests/;-/obj/;-/bin/;-**/.g.cs"
  • dotnet format PatternKit.slnx --verify-no-changes --verbosity minimal
  • dotnet test test\PatternKit.Generators.Tests\PatternKit.Generators.Tests.csproj --configuration Release --no-restore --no-build -p:TestTfmsInParallel=false --logger "console;verbosity=minimal"
  • dotnet test test\PatternKit.Tests\PatternKit.Tests.csproj --configuration Release --framework net8.0 --no-restore --no-build --logger "console;verbosity=minimal"

Note: dotnet test PatternKit.slnx --configuration Release --no-restore --no-build -p:TestTfmsInParallel=false -m:1 --logger "console;verbosity=minimal" timed out locally while stuck in the PatternKit.Tests net8 vstest process; that assembly passed immediately when run directly. CI remains the full-suite gate.

Pull request overview

This PR strengthens FacadeGenerator edge-case handling and increases generator source coverage by adding TinyBDD scenarios, while adjusting contract-first method emission to keep generated signatures faithful to the declared contract when ForceAsync is enabled.

Changes:

  • Added multiple new FacadeGenerator TinyBDD scenarios covering signature-matching failures, missing-map stub emission with ForceAsync, dependency field-name collisions, and nullable/struct generic constraints.
  • Updated contract-first facade method generation to not treat ForceAsync as changing the contract method’s async-ness (preventing invalid interface implementations).

File Description
test/PatternKit.Generators.Tests/FacadeGeneratorTests.cs Adds new scenarios to cover additional generator branches and edge cases (contract-first and auto-facade).
src/PatternKit.Generators/FacadeGenerator.cs Adjusts contract-first method signature generation so ForceAsync does not alter async detection for contract methods.
