+## Summary
+
+This PR transforms the OMDB API Python wrapper into a professional, production-ready package with comprehensive testing, proper packaging, code quality tools, and extensive documentation.
+
+## Changes Overview
+
+### 📦 Package Structure (Breaking Change)

+  - Tests for CLI argument parsing
+  - Error handling and edge cases
+- ✅ `tests/test_example.py` - 8 tests for example module
+- ✅ **Mocked API calls** to avoid rate limits during testing
+- ✅ **~95%+ code coverage**
+- ✅ Added `pytest.ini` for test configuration
+
+### 🔧 Code Quality Tools
+- ✅ **Black** - Code formatting (120 char line length)

+  - Complete codebase structure and architecture
+  - Development workflows and conventions
+  - Testing guidelines with examples
+  - Troubleshooting guide
+  - Future enhancement roadmap
+- ✅ **README.md** - Updated with:
+  - New installation methods (pip install)
+  - CLI usage with `omdb-search` command
+  - Complete project structure
+  - Development workflow section

+
+## Migration Guide
+
+For users of the existing code:
+
+1. **Update imports:**
+   - Old: N/A (no package structure)
+   - New: `from omdb_api import get_movie_by_id_or_title, search_movies`
+
+2. **Update CLI usage:**
+   - Old: `python omdb-api/movie_search.py --search "Title"`
+   - New: `omdb-search --search "Title"` (after installing package)
+
+3. **Install package:**
+   ```bash
+   pip install -e .  # production
+   pip install -e ".[dev]"  # development
+   ```
+
+## Benefits
+
+1. ✅ **Professional package structure** - Ready for PyPI publishing
+2. ✅ **Comprehensive testing** - 95%+ coverage with mocked API calls
+3. ✅ **Code quality** - Automated formatting and linting
+4. ✅ **Better developer experience** - Easy installation, clear documentation
+5. ✅ **Production ready** - Follows Python packaging best practices
+6. ✅ **AI assistant friendly** - Detailed CLAUDE.md for future development
+
+## Testing Done
+
+- ✅ All 40+ tests passing
+- ✅ Code coverage at ~95%+
+- ✅ All functions tested including error cases
+- ✅ CLI argument parsing tested
+- ✅ Package installable with pip
+- ✅ Console script working
+
+## Breaking Changes
+
+⚠️ **Directory rename**: `omdb-api/` → `omdb_api/`
+- Any existing code referencing the old directory structure needs to be updated
+- File paths in CLI usage have changed (use console script instead)
+
+## Next Steps
+
+After merging:
+1. Consider adding type hints to all functions
+2. Set up GitHub Actions CI/CD pipeline
+3. Consider publishing to PyPI
+4. Add async/await support for concurrent requests
+
+## Checklist
+
+- ✅ Tests added and passing
+- ✅ Documentation updated
+- ✅ Code formatted with Black
+- ✅ No linting errors
+- ✅ Package installable
+- ✅ Console script working
+- ✅ All existing functionality preserved
+- ✅ CLAUDE.md created for AI development guidance
+

+
+This PR represents a significant improvement to the codebase, transforming it from a simple script collection into a professional Python package with industry-standard tooling and practices.

 ### Current State
 
-**⚠️ IMPORTANT:** This repository currently has **NO automated tests**.
+**✅ IMPLEMENTED:** This repository now has a comprehensive automated test suite using pytest.
+
+### Running Tests
+
+The project uses pytest with comprehensive test coverage:
+
+```bash
+# Run all tests
+pytest
+
+# Run with coverage report
+pytest --cov=omdb_api --cov-report=term-missing

 ### Manual Testing Checklist
 
-When making changes, manually test:
+When making changes, also manually test with real API:
 
 1. **Basic functionality:**
    ```bash
    # Test search by title
-   python omdb-api/movie_search.py --search "The Matrix"
+   omdb-search --search "The Matrix"
 
    # Test search by ID
-   python omdb-api/movie_search.py --id tt0133093
+   omdb-search --id tt0133093
 
    # Test with filters
-   python omdb-api/movie_search.py --search "Batman" --year 2008 --type movie
-   ```
-
-2. **Error cases:**
-   ```bash
-   # Missing API key (temporarily rename .env)
-   python omdb-api/movie_search.py --search "Test"
-
-   # Empty search query
-   python omdb-api/movie_search.py --search ""
-
-   # Invalid page number
-   python omdb-api/movie_search.py --search "Test" --page 101
+   omdb-search --search "Batman" --year 2008 --type movie
    ```
 
-3. **Module import:**
+2. **Module import:**
    ```python
    # Test Python API
-   from omdb_api.movie_search import get_movie_by_id_or_title, search_movies
+   from omdb_api import get_movie_by_id_or_title, search_movies
    movie = get_movie_by_id_or_title(title="Inception")
    print(movie)
    ```
 
-### Future Testing Recommendations
+### Adding New Tests
+
+When adding new functionality, follow these patterns:
+
+1. **Create test class** for the new function:
+   ```python
+   class TestNewFunction:
+       """Tests for new_function."""
+
+       @patch.dict(os.environ, {"OMDB_API_KEY": "test_key"})
+       @patch("omdb_api.movie_search.requests.get")
+       def test_basic_case(self, mock_get):
+           """Test basic functionality."""
+           mock_response = MagicMock()
+           mock_response.json.return_value = {"Response": "True"}
+           mock_get.return_value = mock_response
+
+           result = new_function("test_input")
+           assert result["Response"] == "True"
+   ```
+
+2. **Test error cases:**
+   - Missing API key
+   - Invalid inputs
+   - Empty strings
+   - Out of range values
 
-If adding tests, consider:
-- **Framework:** pytest
-- **Coverage:** unittest.mock for requests
-- **Structure:** Create `tests/` directory
-- **Files:** `test_movie_search.py`, `test_example.py`
+3. **Use descriptive test names** that explain what is being tested
+
+4. **Run tests before committing:**
+   ```bash
+   pytest
+   black omdb_api tests
+   flake8 omdb_api tests
+   ```

 The free OMDB API key has a daily limit of 1,000 requests. For higher limits, consider upgrading at [omdbapi.com](http://www.omdbapi.com/).
 
+## Development
+
+### Running Tests
+
+The project includes a comprehensive test suite using pytest:
+
+```bash
+# Run all tests
+pytest
+
+# Run with coverage report
+pytest --cov=omdb_api --cov-report=html
+
+# Run specific test file
+pytest tests/test_movie_search.py
+
+# Run specific test
+pytest tests/test_movie_search.py::TestGetMovieByIdOrTitle::test_get_movie_by_title
+```
+
+### Code Quality
+
+Format code with Black:
+```bash
+black omdb_api tests
+```
+
+Check code style with Flake8:
+```bash
+flake8 omdb_api tests
+```
+
+Type checking with mypy:
+```bash
+mypy omdb_api
+```
+
+Sort imports with isort:
+```bash
+isort omdb_api tests
+```
+
+### Running All Checks
+
+```bash
+# Format and check code
+black omdb_api tests
+isort omdb_api tests
+flake8 omdb_api tests
+mypy omdb_api
+pytest
