tests +3. **OptimizelyUserContextTests_Decide_CMAB.swift** - Integration tests for CMAB decisions +4. **OptimizelyUserContextTests_Decide_Async.swift** - Async decision tests (Note: C# is synchronous) + +### 1.2 Modified Test Files +- **DecisionServiceTests_Experiments.swift** - Added CMAB experiment tests +- **DecisionListenerTests.swift** - Added CMAB notification tests + +### 1.3 Swift Test Coverage Areas + +#### A. **Bucketing Tests** (`BucketTests_BucketToEntity.swift`) +- ✅ Test `bucketToEntityId()` method +- ✅ Bucket to CMAB dummy entity ID +- ✅ Traffic allocation for CMAB experiments +- ✅ Mutex rule checking for CMAB experiments +- ✅ Zero traffic allocation handling +- ✅ Hash generation and bucket value calculation + +#### B. **CMAB Service Tests** (`CmabServiceTests.swift`) +**Cache Management:** +- ✅ Cache hit with matching attributes hash +- ✅ Cache miss when attributes change +- ✅ Cache invalidation options (`ignoreCmabCache`, `resetCmabCache`, `invalidateUserCmabCache`) +- ✅ Cache key generation + +**Attribute Filtering:** +- ✅ Filter attributes based on experiment's `attributeIds` +- ✅ Hash attributes deterministically (same attrs = same hash, different order) +- ✅ Handle missing attributes gracefully + +**API Integration:** +- ✅ Fetch decision from CMAB client +- ✅ Handle CMAB client errors +- ✅ Retry logic and error propagation +- ✅ UUID generation and caching + +**Synchronous/Asynchronous:** +- ✅ Synchronous decision (C# equivalent) +- ✅ Async decision with completion handler (Not needed for C#) + +#### C. **Decision Service Tests** (`DecisionServiceTests_Experiments.swift`) +**CMAB Experiment Flow:** +- ✅ `GetVariation()` with CMAB traffic allocation +- ✅ CMAB experiment with zero traffic allocation +- ✅ CMAB not supported in sync mode (C# is always sync) +- ✅ User bucketed into CMAB variation +- ✅ CMAB service error handling +- ✅ Fall back to standard bucketing on CMAB failure + +**Traffic Allocation:** +- ✅ Full traffic allocation (10000) +- ✅ Zero traffic allocation (0) +- ✅ Partial traffic allocation + +#### D. **User Context Decide Tests** (`OptimizelyUserContextTests_Decide_CMAB.swift`) +**Basic CMAB Decision:** +- ✅ `Decide()` with CMAB experiment +- ✅ Variation key returned correctly +- ✅ CMAB UUID generated and returned +- ✅ Feature enabled status +- ✅ Variables resolved correctly + +**Impression Events:** +- ✅ Impression event sent with CMAB UUID +- ✅ Event metadata includes `cmab_uuid` field +- ✅ Rule type and flag key in metadata +- ✅ Variation key in metadata + +**Multiple Decisions:** +- ✅ `DecideForKeys()` with mixed CMAB/non-CMAB experiments +- ✅ CMAB service called correct number of times +- ✅ Cache shared across multiple decisions + +**Cache Options:** +- ✅ User profile service caching (skip with `ignoreUserProfileService`) +- ✅ CMAB cache options (`ignoreCmabCache`, `resetCmabCache`, `invalidateUserCmabCache`) +- ✅ Cache behavior with repeated decisions + +**Error Handling:** +- ✅ CMAB service returns error +- ✅ Decision reasons include CMAB error message +- ✅ Fallback to null variation on error + +**Notification Tests:** +- ✅ Decision notification includes CMAB UUID +- ✅ Flag decision notification +- ✅ Impression event notification + +--- + +## Phase 2: C# Test Structure

Compilation in Tests +**Important Discovery:** CMAB tests do NOT need `#if USE_CMAB` directives! + +**Reason:** +- Test project (`OptimizelySDK.Tests.csproj`) targets **.NET 4.5 only** +- Production SDK multi-targets (NET35, NET40, NETSTANDARD1_6, NETSTANDARD2_0) +- In production code: `#if !(NET35 || NET40 || NETSTANDARD1_6)` defines `USE_CMAB` +- Tests always run on NET45 where CMAB is **always available** +- Same pattern as ODP tests (no conditionals in `OdpTests/` files) + +**Pattern to Follow:** +```csharp +// ✅ Correct - Like ODP tests +[TestFixture] +public class BucketerCmabTest +{ +

_service.GetDecision(...); + + // Assert - Verify results + Assert.AreEqual(expected, result); + _mockCmabClient.Verify(...); +} +``` + +#### Helper Methods: +```csharp +private ProjectConfig CreateProjectConfig(string ruleId, Experiment experiment, ...) +{ + // Create test configuration +} + +private OptimizelyUserContext CreateUserContext(string userId, ...) +{ + // Create test user
