## Quick Start



### Run All Tests



```bash

# Run core tests (fast, high-value)

python tests/0.core/caching/runner.py



# Run unit tests

python tests/1.unit/caching_unit/runner.py



# Run integration tests

python tests/2.integration/caching/runner.py



# Run advance tests (v1.0.0+)

python tests/3.advance/caching/runner.py

```



### Using Pytest Directly



```bash

# Run all caching tests

pytest tests/ -m xwsystem_caching -v



# Run core tests only

pytest tests/0.core/caching/ -m xwsystem_core -v



# Run security tests

pytest -m "xwsystem_security and xwsystem_caching" -v



# Run performance tests

pytest -m "xwsystem_performance and xwsystem_caching" -v

```



## Test Categories

- **Markers:** `xwsystem_core`, `xwsystem_caching`



### 🧩 Unit Tests (`1.unit/caching/`)

- **Purpose:** Component-level validation

- **Speed:** < 5 minutes total

- **Focus:** Individual classes and methods

- **Markers:** `xwsystem_unit`, `xwsystem_caching`



### 🔗 Integration Tests (`2.integration/caching/`)

- **Purpose:** End-to-end scenarios

- **Speed:** < 15 minutes total

- **Focus:** Real-world workflows

- **Markers:** `xwsystem_integration`, `xwsystem_caching`



### 🎓 Advance Tests (`3.advance/caching/`)

- **Purpose:** Excellence validation (v1.0.0+)

## Installation Verification



```bash

python tests/verify_installation.py

```



Expected output:

```

================================================================================

🔍 Verifying xwsystem installation...

================================================================================



Testing Import...

✅ Import successful



Testing Caching Functionality...

✅ Caching functionality works



Testing Dependencies...

✅ pytest available



================================================================================

🎉 SUCCESS! xwsystem is ready to use!

================================================================================

```



## Markers



All tests use pytest markers for categorization:



```ini

xwsystem_core           # Core functionality tests

xwsystem_unit           # Unit tests

xwsystem_integration    # Integration tests

xwsystem_advance        # Advance tests (v1.0.0+)

xwsystem_security       # Security excellence (Priority #1)

xwsystem_performance    # Performance excellence (Priority #4)

xwsystem_caching        # Caching module specific

slow                   # Slow tests (> 1 second)

```



## Common Commands



```bash

# Run specific markers

pytest -m xwsystem_core

pytest -m xwsystem_security

pytest -m "xwsystem_unit and not slow"



# Stop on first failure

pytest -x



# Show local variables on failure

pytest -l



# Very verbose

pytest -vv



# With coverage

pytest --cov=exonware.xwsystem.caching --cov-report=html

```



## Test Quality Standards



Following **GUIDELINES_TEST.md**:



✅ **Root Cause Fixing** - Never rig tests, always fix problems  

✅ **Stop on First Failure** (`-x`) - Fast feedback  

✅ **No Warning Suppression** - Warnings indicate real issues  

✅ **Comprehensive Coverage** - 80%+ for critical modules  

✅ **Security First** - Priority #1 testing  

✅ **Performance Benchmarks** - O(1) LFU validation  



## Performance Targets



- **Core Tests:** < 30 seconds

- **Unit Tests:** < 5 minutes

- **Integration Tests:** < 15 minutes

- **Advance Tests:** < 30 minutes



## Contributing



When adding new tests:



1. Place in correct layer (core/unit/integration/advance)

2. Use appropriate markers

3. Follow naming convention: `test_<action>_<expected>`

4. Add docstrings explaining purpose

5. Include Given/When/Then for integration tests

6. Update this README if adding new test categories



## Notes



- **Advance tests** are OPTIONAL until v1.0.0

- **All tests** must pass before releases

- **No rigged tests** - fix problems, don't hide them

- **Security tests** have highest priority (#1)
