Pull request overview
This PR introduces 8 new packages for advanced experimentation scenarios including rollout management, targeting, distributed state, audit logging, REST API administration, multi-armed bandit algorithms, and automatic stopping rules. The changes add comprehensive BDD-style tests achieving 95%+ code coverage and full documentation integrated into the docfx structure.
Key Changes
- Added rollout packages (ExperimentFramework.Rollout) for percentage-based and time-staged deployments
- Implemented targeting system (ExperimentFramework.Targeting) with rule-based user segmentation
- Created distributed state management with Redis backend support
- Added audit, admin API, bandit algorithms, and auto-stop functionality
- Integrated configuration extensibility through handler interfaces
- Added comprehensive test coverage using TinyBDD framework

Add tests for: - BanditServiceCollectionExtensions (8 lines previously uncovered) - ConfigurationExtensionRegistry (7 lines previously uncovered) - ConfigurationExtensionServiceCollectionExtensions (8 lines previously uncovered) - TargetingSelectionModeHandler Apply method (4 lines previously uncovered) Improves overall patch coverage toward 95%+ target.
Add /p:BuildInParallel=false to both build commands in the CI workflow to prevent race conditions when building ExperimentFramework.Generators. The source generator's deps.json file was being accessed simultaneously by multiple build nodes, causing intermittent build failures.
- Add AddTrial<StableService> to tests that use ExperimentFrameworkBuilder.Define() since Define() calls Build() internally which requires at least one trial - Fix Apply_uses_targeting_modes_constant test to correctly compare ModeType (lowercase "targeting" for YAML) with TargetingModes.Targeting (capitalized) using case-insensitive comparison
Add tests for: - Built-in configuration handlers (timeout, custom, logging) via registry - Data package AddExperimentDataConfiguration method - CircuitBreakerDecoratorHandler edge cases (unsupported types) - OutcomeCollectionDecoratorHandler edge cases (unsupported types) These tests exercise internal handlers indirectly through the ConfigurationExtensionRegistry, covering previously untested code paths like type resolution failures and unsupported option types.
