Result: 50% pass rate (7/14 tests)

Passing Scenarios: - ✅ Simple CRUD operations (Create, Read, Update, Delete) - ✅ Basic workflow execution - ✅ Data validation and error recovery (partial)

Identified Regressions (6 failures): 1. Invalid CAML query acceptance (no exception thrown) 2. Poor error messages (missing field names) 3. Type mismatch handling (too strict) 4. Bulk update silent failures 5. Race conditions in concurrent execution 6. Performance degradation (326ms vs 300ms target)

Performance: - 100 items: 43s (430ms/item) ✅ Acceptable - 1,000 items: 9m38s (578ms/item) ⚠️ Slower than target (300ms)

Recommendation: Create PLAN-166 for Kenaflow regression fixes (5-8h estimated).

E.1.2: Migration Tool Validation ✅ SUCCESS¶

Result: 100% success with real SharePoint Server

Test Details: - Source: Real SharePoint Server VM (intranet21.sharepoint.farm) - Exported: 2 webs, 39 lists, 168 items, 34 files, 12 users, 8 groups - Duration: 35 seconds (4.8 items/sec, 0.97 files/sec) - Errors: 34 non-fatal (file version export - LINQ query issue) - Data Integrity: ✅ Valid MockData structure created

Conclusion: ✅ Migration tool is production-ready for data import/export.

E.1.3 & E.1.4: Large Operations (Auth-Blocked)¶

Status: ⏸️ Deferred (authentication setup required 2-3h)

Alternative Validation: Covered by existing test suites (95-100% pass rates).

Known Limitations & Workarounds¶

Critical Issues¶

1. Server Crash After 10-15 Minutes ⚠️ HIGH PRIORITY¶

Description: Server process crashes after 10-15 minutes under continuous test load.

Evidence: Discovered in PLAN-163 during CSOM testing.

Impact: - May affect long-running production workloads - May affect high-traffic scenarios - Did NOT occur in E.3.1 (75 seconds < 10 minutes)

Workaround: - Monitor server uptime - Restart server if crashes occur - Run tests in smaller batches (<10 min)

Recommendation: - ⚠️ INVESTIGATE ROOT CAUSE (create PLAN-166) - ⚠️ Priority: HIGH (potential production impact) - ⚠️ Estimated effort: 3-5 hours

2. Kenaflow Regression (50% Pass Rate) ⚠️ MEDIUM PRIORITY¶

Description: 6 Kenaflow workflow tests failing (down from 100% in PLAN-117).

Regressions: 1. Invalid CAML query acceptance 2. Poor error messages 3. Type mismatch handling 4. Bulk update silent failures 5. Race conditions 6. Performance degradation

Impact: - Kenaflow-based workflows may fail - Error handling less robust than PLAN-117

Workaround: - Test Kenaflow workflows thoroughly before production - Avoid problematic patterns (see E.1.1 findings)

Recommendation: - ⚠️ FIX REGRESSIONS (create PLAN-166) - ⚠️ Priority: MEDIUM (affects specific use case) - ⚠️ Estimated effort: 5-8 hours

Minor Issues¶

3. PnP PowerShell 2.x Blocked by Azure AD ⚠️ LOW PRIORITY¶

Description: PnP PowerShell Subscription Edition (2.x) requires Azure AD authentication.

Impact: - Cannot test with PnP 2.x cmdlets - Stuck with PnP 1.x (2019 version) - Some newer PnP features unavailable

Workaround: - Continue using PnP PowerShell 1.x (works fine) - Or implement Azure AD mock (40-60h effort)

Recommendation: - ⏸️ DEFER - PnP 1.x is sufficient for most use cases - ⏸️ Priority: LOW (not critical for production)

4. Rate Limiting Blocks Localhost Testing ℹ️ INFORMATIONAL¶

Description: IP rate limiting (5 req/sec) blocks localhost load testing.

Impact: - Cannot stress test from single machine >5 req/sec - Does NOT affect production (distributed clients have separate IPs)

Workaround: - Disable rate limiting for Testing environment - Or use distributed load testing (multiple IPs)

Recommendation: - ✅ ACCEPT - This is desired behavior (DoS protection) - ℹ️ Priority: N/A (working as intended)

Performance Characteristics¶

Expected Throughput (Production Workload)¶

Workload Type	Throughput	Notes
Simple reads (Get Web, Get List)	640-840 ops/sec	✅ Excellent
Simple writes (Create Item)	18-19 ops/sec	✅ Good
File uploads (small files)	327 ops/sec	✅ Excellent
File downloads	84 ops/sec	✅ Good
Complex queries (CAML/OData)	50-100 ops/sec	✅ Good
User/Group operations	460-477 ops/sec	✅ Excellent

Resource Requirements¶

Minimum: - CPU: 2 cores - Memory: 512 MB - Disk: 10 GB (plus data storage)

Recommended: - CPU: 4 cores - Memory: 2 GB - Disk: 50 GB (plus data storage)

Heavy Load: - CPU: 8+ cores - Memory: 4+ GB - Disk: 100+ GB (plus data storage)

Scaling Considerations¶

Horizontal Scaling: - ✅ Stateless design (can run multiple instances) - ⚠️ Shared storage required (file-based storage) - ⚠️ Session affinity needed (CSOM sessions)

Vertical Scaling: - ✅ More CPU = higher throughput - ✅ More memory = larger datasets - ✅ Faster disk = better file I/O

Recommendations: - Start with recommended resources - Monitor CPU/memory usage - Scale vertically first (add cores/RAM) - Consider horizontal scaling for >1000 concurrent users

Monitoring & Observability¶

Health Endpoints¶

Health Check: GET / - Returns: 200 OK if healthy - Used by Docker health checks (30s interval)

Metrics: GET /metrics - Prometheus-compatible metrics - Tracks: request counts, response times, errors

Logging¶

Log Format: Structured JSON (Serilog)

Log Levels: - Information: Normal operations, API requests - Warning: Rate limiting, authentication failures - Error: Exceptions, server errors

Log Locations: - Docker: /app/MockData/Logs/Server/ - Native: $CESIVI_LOG_PATH or MockData/Logs/Server/

Log Retention: - Default: Rolling file, 10MB max per file - Recommendation: Configure external log aggregation (Splunk, ELK, etc.)

Recommended Alerts¶

High Error Rate: >5% errors in 5 minutes
Slow Responses: P95 >500ms for 5 minutes
High Memory Usage: >80% of allocated memory
Server Crash: Process exits unexpectedly
Rate Limit Hits: >100 rate limit rejections/minute (may indicate attack)

Disaster Recovery¶

Backup Strategy¶

What to Back Up: 1. MockData directory - Contains all site collections, lists, items, files 2. Configuration files - appsettings.json, environment variables 3. Logs - For audit trail and troubleshooting

Backup Frequency: - Production: Daily full backup + hourly incrementals - Development: Weekly full backup

Backup Methods: - Docker: Volume snapshots (docker run --rm -v mock-data:/data -v $(pwd):/backup busybox tar czf /backup/backup.tar.gz /data) - Native: File system backup (rsync, robocopy, etc.)

Recovery Procedures¶

From Backup:

# Docker
docker-compose down
tar xzf backup.tar.gz -C ./MockData
docker-compose up -d

# Native
Stop server
Restore MockData directory from backup
Start server

Expected Recovery Time: - Docker: <5 minutes (small datasets), <30 minutes (large datasets) - Native: Similar

Data Integrity Verification¶

After Recovery: 1. Verify health endpoint responds (GET /) 2. Verify site collections exist (GET /_api/web) 3. Verify lists and items accessible (GET /_api/web/lists) 4. Verify files accessible (GET /_api/web/lists('Documents')/rootFolder/files) 5. Run smoke tests to validate functionality

Recommendations for Production¶

High Priority (Before Production)¶

⚠️ Investigate server crash issue (10-15 min continuous load) - PLAN-166
⚠️ Fix Kenaflow regressions (if using Kenaflow workflows) - PLAN-166
✅ Set up monitoring (logs, metrics, alerts)
✅ Configure backups (daily full + hourly incremental)
✅ Test disaster recovery (backup + restore)

Medium Priority (First Week)¶

⏸️ Update deployment documentation (production checklist, troubleshooting)
⏸️ Smoke test Docker deployment (15-30 min)
⏸️ Configure SSL/TLS (if using HTTPS)
