Add comprehensive test suite with 100+ tests

New test files:
- test_edge_cases.py: Edge cases, error handling, validation (60+ tests)
- test_web_routes.py: Web pages and HTML endpoints (40+ tests)
- conftest.py: Shared fixtures and configuration
- README.md: Test documentation and usage guide

Test coverage includes:
- API endpoints (all endpoints)
- Edge cases and error handling
- Book abbreviations and normalization
- Search functionality
- Content validation
- Web page routes
- HTML structure and metadata
- Navigation and accessibility
- Performance with large datasets
- Boundary conditions

Fixtures (shared via conftest.py):
- client: TestClient for requests
- sample_verses: Common verse references
- sample_books: Sample book names
- book_abbreviations: Abbreviation mappings
- bible_facts: Known Bible facts

Updated test_api.py to use shared fixtures from conftest.py.

Run with: uv run pytest tests/ -v

+# KJV Study API Tests
+
+Comprehensive test suite for the KJV Study API and web application.
+
+## Test Files
+
+### `test_api.py`
+Core API endpoint tests covering:
+- Health checks
+- Verse endpoints (single, range, verse of the day)
+- Book endpoints (list, details, chapters, full text)
+- Bible endpoint (entire Bible)
+- Search functionality
+- Interlinear data
+- Cross-references
+- Topics and reading plans
+- Book name normalization
+
+### `test_edge_cases.py`
+Edge case and error handling tests:
+- Invalid inputs and error responses
+- Verse range edge cases
+- Book abbreviations (comprehensive)
+- Search functionality edge cases
+- Book boundaries (shortest, longest, etc.)
+- Cross-references edge cases
+- Interlinear data edge cases
+- Topics and reading plans edge cases
+- Performance tests with large data
+- Content validation
+
+### `test_web_routes.py`
+Web page and HTML endpoint tests:
+- Homepage
+- Book listing and detail pages
+- Chapter and verse pages
+- Search pages
+- Topics and reading plans pages
+- Resource pages
+- 404 handling
+- Redirects
+- HTML structure and metadata
+- Navigation elements
+- Accessibility features
+- Content types
+
+### `conftest.py`
+Shared pytest configuration and fixtures:
+- `client` - TestClient for API requests
+- `sample_verses` - Common verse references
+- `sample_books` - Sample book names
+- `book_abbreviations` - Abbreviation mappings
+- `bible_facts` - Known Bible facts for validation
+
+## Running Tests
+
+### Run all tests
+```bash
+uv run pytest tests/ -v
+```
+
+### Run specific test file
+```bash
+uv run pytest tests/test_api.py -v
+```
+
+### Run specific test class
+```bash
+uv run pytest tests/test_api.py::TestVerseEndpoints -v
+```
+
+### Run specific test
+```bash
+uv run pytest tests/test_api.py::TestVerseEndpoints::test_get_single_verse -v
+```
+
+### Run with coverage
+```bash
+uv run pytest tests/ --cov=kjvstudy_org --cov-report=html
+```
+
+### Run tests in parallel (faster)
+```bash
+uv run pytest tests/ -n auto
+```
+
+## Test Categories
+
+### Functional Tests
+- API endpoints return correct data
+- Web pages load correctly
+- Search functionality works
+- Data integrity
+
+### Edge Cases
+- Invalid inputs
+- Boundary conditions
+- Error handling
+- Performance with large datasets
+
+### Integration Tests
+- Book name normalization
+- Cross-references linking
+- Interlinear data availability
+- Content validation
+
+## Fixtures
+
+Fixtures are defined in `conftest.py` and automatically available to all test files:
+
+- **client**: FastAPI TestClient for making requests
+- **sample_verses**: Dictionary of common verse references
+- **sample_books**: Dictionary of sample book names
+- **book_abbreviations**: Mapping of abbreviations to full names
+- **bible_facts**: Known facts about the KJV Bible
+
+## Best Practices
+
+1. **Use fixtures** - Leverage shared fixtures from conftest.py
+2. **Descriptive names** - Test names should describe what they test
+3. **Arrange-Act-Assert** - Follow AAA pattern in tests
+4. **One assertion per concept** - Keep tests focused
+5. **Test edge cases** - Don't just test happy paths
+6. **Use parametrize** - For testing multiple similar cases
+
+## Adding New Tests
+
+When adding new functionality:
+
+1. Add API tests to `test_api.py`
+2. Add edge case tests to `test_edge_cases.py`
+3. Add web route tests to `test_web_routes.py`
+4. Update fixtures in `conftest.py` if needed
+5. Run tests to ensure they pass
+6. Add documentation if needed
+
+## CI/CD Integration
+
+These tests are designed to run in CI/CD pipelines:
+
+```yaml
+# Example GitHub Actions workflow
+- name: Run tests
+  run: uv run pytest tests/ -v --cov
+```
