+# Stats Spotlight SID Test Suite
+
+## Overview
+This test suite validates the Stats Spotlight SID functionality, specifically testing segment-routing spotlight configuration and sensor management.
+
+## Test File
+- `TEST_Stats_Spotlight_Sid.py` - Main test file for spotlight functionality
+
+## Test Coverage
+
+### 1. `test_enable_spotlight`
+Tests basic spotlight enabling functionality and verifies sensor count increases.
+
+### 2. `test_disable_spotlight` 
+Tests normal spotlight disabling and verifies sensors are reduced.
+
+### 3. `test_spotlight_sensor_management`
+Tests the full lifecycle of sensor count changes during spotlight operations.
+
+### 4. `test_no_segment_routing_config` ✓ **NEWLY COMPLETED**
+Tests the "no segment-routing" command functionality:
+1. Re-enables spotlighting (verifies previous functionality works)
+2. Disables spotlighting using the "no segment-routing" command
+3. Verifies that the correct number of sensors are deleted
+
+**Key difference**: The "no segment-routing" command removes ALL spotlight-related sensors, while normal spotlight disable may leave some sensors active.
+
+## Running the Tests
+
+### Direct execution:
+```bash
+cd tests/Valimar/Stats
+python3 TEST_Stats_Spotlight_Sid.py
+```
+
+### With pytest (if available):
+```bash
+cd tests/Valimar/Stats
+pytest TEST_Stats_Spotlight_Sid.py -v
+```
+
+## Test Results
+All tests currently **PASS** including the newly implemented "no segment-routing" test.
+
+## Implementation Notes
+- Tests use mock implementations for hardware interactions
+- Sensor count tracking simulates real hardware behavior
+- Proper setup/teardown ensures clean test isolation
+- Comprehensive logging for debugging and verification
+
+## Hardware Testing
+These tests use mock implementations. For actual hardware validation:
+1. Replace mock methods with real device communication
+2. Update sensor count retrieval to query actual hardware
+3. Implement real "segment-routing" and "no segment-routing" commands
