+# Quick Test Reference Guide
+
+## 🚀 Running Tests
+
+### Setup (First Time Only)
+```bash
+# Navigate to project directory
+cd /edge-ai-suites/metro-ai-suite/image-based-video-search
+
+# Create and activate virtual environment
+python3 -m venv ./test-venv
+
+source test-venv/bin/activate
+```
+### Install Requirements 
+```bash
+pip install -r ./test/requirements.txt
+```
+
+### Run All Tests with Coverage
+```bash
+# Note: You must temporarily modify server.py imports before running tests
+# See "Important Notes" section below
+
+# Run all tests with coverage
+pytest test/ --cov=src/feature-matching --cov-report=term-missing
+
+# Run all tests with HTML coverage report
+pytest test/ --cov=src/feature-matching --cov-report=html
+```
+
+### Run Individual Test Files
+```bash
+pytest test/test_encoder.py -v
+pytest test/test_milvus_utils.py -v
+pytest test/test_schemas.py -v
+pytest test/test_server.py -v
+```
+
+### Run Specific Test
+```bash
+pytest test/test_encoder.py::TestBase64ImageProcessor::test_processor_initialization_default_size -v
+```
+
+## 📊 Current Test Results
+
+- **Total Tests:** 92
+- **Passing:** 88 (95.7%)
+- **Failing:** 4 (4.3%)
+- **Overall Coverage:** 95%
+
+### Coverage by Module
+- encoder.py: 100%
+- milvus_utils.py: 100%
+- schemas.py: 100%
+- server.py: 92%
+
+## ⚠️ Important Notes
+
+### Temporary Import Modification Required
+
+Before running tests, you need to temporarily modify `src/feature-matching/server.py`:
+
+**Change FROM (relative imports):**
+```python
+from .encoder import Base64ImageProcessor
+from .milvus_utils import (...)
+from .schemas import PayloadSchema, TensorSchema
+```
+
+**TO (absolute imports):**
+```python
+from encoder import Base64ImageProcessor
+from milvus_utils import (...)
+from schemas import PayloadSchema, TensorSchema
+```
+
+**Quick command to make this change:**
+```bash
+cd src/feature-matching
+cp server.py server.py.bak  # Backup original
+sed -i 's/from \.encoder import/from encoder import/g' server.py
+sed -i 's/from \.milvus_utils import/from milvus_utils import/g' server.py
+sed -i 's/from \.schemas import/from schemas import/g' server.py
+```
+
+**Restore after testing:**
+```bash
+cd src/feature-matching
+mv server.py.bak server.py  # Restore original
+```
+
+### Why This Is Needed
+The `src/feature-matching` directory uses hyphens (not valid in Python module names), so the tests add it to `sys.path` and import directly. The relative imports in `server.py` won't work in this configuration, so we temporarily convert them to absolute imports.
+
+## 📁 Generated Reports
+
+1. **htmlcov/index.html** - Interactive HTML coverage report
+
+### View HTML Report
+```bash
+# Open in default browser
+xdg-open htmlcov/index.html
+
+# Or specify browser
+firefox htmlcov/index.html
+google-chrome htmlcov/index.html
+```
+
+## 🔧 Environment
+
+- Python: 3.12.3
+- Pytest: 8.4.2
+- Virtual Env: test-venv
+- Working Directory: `/edge-ai-suites/metro-ai-suite/image-based-video-search`
+
+## 📚 Additional Resources
