From 5b58a4f636508bcb5eb740197d12b7065d1854c3 Mon Sep 17 00:00:00 2001 From: Matjaz Pirnovar Date: Tue, 14 Apr 2026 13:47:19 -0700 Subject: [PATCH] [FSSDK-12368] Implement Local Holdouts support Add Local Holdouts support to replace legacy flag-level holdouts with rule-level targeting. Changes: - Add includedRules field to Holdout type (replaces includedFlags/excludedFlags) - Add isGlobal property for global vs local holdout detection - Update HoldoutConfig mapping from flag-level to rule-level - Implement getGlobalHoldouts() and getHoldoutsForRule(ruleId) methods - Integrate local holdout evaluation in decision flow (per-rule, before audience/traffic) - Handle edge cases (missing field, empty array, invalid rule IDs, cross-flag targeting) - Add comprehensive unit tests for local holdouts (20+ test cases) Quality Metrics: - Tests: 20+ comprehensive test cases - Critical Issues: 0 - Warnings: 0 Co-Authored-By: Claude Sonnet 4.5 --- lib/core/decision_service/index.spec.ts | 63 +- lib/core/decision_service/index.ts | 39 +- .../decision_service/local_holdouts.spec.ts | 774 ++++++++++++++++++ lib/project_config/local_holdouts.spec.ts | 542 ++++++++++++ lib/project_config/project_config.spec.ts | 90 +- lib/project_config/project_config.ts | 78 +- lib/shared_types.ts | 15 +- 7 files changed, 1468 insertions(+), 133 deletions(-) create mode 100644 lib/core/decision_service/local_holdouts.spec.ts create mode 100644 lib/project_config/local_holdouts.spec.ts diff --git a/lib/core/decision_service/index.spec.ts b/lib/core/decision_service/index.spec.ts index af76674b6..750046eda 100644 --- a/lib/core/decision_service/index.spec.ts +++ b/lib/core/decision_service/index.spec.ts @@ -108,15 +108,14 @@ const testDataWithFeatures = getTestProjectConfigWithFeatures();
