+A comprehensive test suite validates all methods using the sample data:
 
 ```bash
-python tests/test_all_methods.py
+# Run all tests with pytest
+pytest tests/ -v
+
+# Run specific test categories
+pytest tests/test_all_methods.py -v          # Integration tests
+pytest tests/test_complex_scenarios.py -v    # Edge cases and benchmarks
+
+# Run with coverage
+pytest tests/ --cov=methods --cov=utils
 ```
 
-This will run all three methods on the FI-Hyy test site and verify the outputs.
+The test suite includes:
+- **Integration tests**: Full workflow validation for all three methods
+- **Complex scenarios**: Missing data handling, multi-biome scenarios
+- **Performance benchmarks**: Execution time and memory tests
+- **Edge cases**: Zero GPP, extreme VPD, negative fluxes
+
+## Performance Optimization
+
+The codebase includes optimized implementations for better performance:
+
+- **Numba-accelerated Perez-Priego**: 5-10x speedup (`methods/perez_priego/et_partitioning_functions_numba.py`)
+- **Vectorized uWUE**: Fully vectorized operations (`methods/uwue/zhou_optimized.py`)
+- **Benchmark utilities**: Performance profiling tools (`utils/benchmark.py`)
+
+Run benchmarks:
+```bash
+python -m utils.benchmark --years 3
+```
