+# Test Generator Examples
+
+Real-world examples of comprehensive test suite generation for frontend components, backend APIs, and test coverage improvement.
+
+## Files in This Directory
+
+### [react-component-testing.md](react-component-testing.md)
+Complete example of generating test suite for React component with TanStack Query - from no tests to 100% coverage. Shows unit tests, integration tests, user interaction tests, and accessibility tests.
+
+**Scenario**: Payment form component with validation, API calls, and error handling - initially untested
+**Result**: 42 tests generated, 100% coverage, caught 3 bugs during testing
+**Technologies**: React 19, Vitest, Testing Library, TanStack Query
+
+### [api-endpoint-testing.md](api-endpoint-testing.md)
+Backend API testing example showing test generation for FastAPI endpoints - authentication, validation, database operations, and error handling.
+
+**Scenario**: User management API endpoints with CRUD operations - 35% test coverage
+**Result**: Coverage improved from 35% → 94%, 67 tests generated, found 5 edge case bugs
+**Technologies**: FastAPI, pytest, SQLModel, PostgreSQL
+
+### [test-coverage-workflow.md](test-coverage-workflow.md)
+Step-by-step workflow for analyzing low-coverage codebase and systematically generating tests to reach 80%+ coverage.
+
+**Scenario**: Legacy codebase with 42% coverage needs improvement for production deployment
+**Result**: Coverage 42% → 87% over 3 days, 156 tests generated, zero production bugs first month
+**Technologies**: Multi-language (TypeScript + Python), Vitest + pytest

+# Test Generator Templates
+
+Copy-paste templates for common testing scenarios - customize for your needs.
+
+## Files in This Directory
+
+### [unit-test-template.md](unit-test-template.md)
+Ready-to-use unit test templates for TypeScript (Vitest) and Python (pytest) with AAA pattern, fixtures, and common test cases.
+
+**When to use**: Creating new unit test files
+**Languages**: TypeScript, Python
+
+### [integration-test-template.md](integration-test-template.md)
+Templates for integration tests covering API endpoints, database interactions, and multi-component workflows.
+
+**When to use**: Testing interactions between components or services
+**Languages**: TypeScript, Python

+
+## Usage
+
+1. **Copy template** to your test directory
+2. **Replace placeholders** (e.g., `ComponentName`, `YourService`)
+3. **Customize** test cases for your specific needs
+4. **Add tests** as you discover edge cases
+
+## Template Conventions
+
+**Placeholders**:
+- `ComponentName` - Replace with your component name
+- `functionName` - Replace with your function name
+- `YourService` - Replace with your service class name
+- `...` - Add more test cases
+
+**Comments**:
+- `// TODO:` - Action items to complete
+- `// CUSTOMIZE:` - Areas to customize for your use case
