Subject: [PATCH 1/2] Add comprehensive test suite with 33 unit tests

- Created test_main.py with full test coverage for all API endpoints
- Added tests for chat tools (create_issue, list_repos, list_issues, etc.)
- Added tests for authentication and repository management
- Added pytest and pytest-asyncio to requirements.txt
- All 33 tests passing successfully

+# Testing Guide
+
+This document describes the test suite for the OMI GitHub Issues Integration application.
+
+## Overview
+
+The project includes a comprehensive test suite with **33 unit tests** covering all major functionality:
+
+- ✅ API endpoint testing
+- ✅ Chat tools functionality
+- ✅ Authentication flows
+- ✅ Repository management
+- ✅ Error handling
+- ✅ Input validation
+
+## Running Tests
+
+### Prerequisites
+
+Install the test dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+This installs:
+- `pytest==7.4.3` - Testing framework
+- `pytest-asyncio==0.21.1` - Async test support
+
+### Run All Tests
+
+```bash
+pytest test_main.py -v
+```
+
+### Run Specific Test Classes
+
+```bash
+# Test health endpoint only
+pytest test_main.py::TestHealthEndpoint -v
+
+# Test create issue tool
+pytest test_main.py::TestCreateIssueTool -v
+
+# Test authentication
+pytest test_main.py::TestAuthEndpoints -v
+```
+
+### Run with Coverage (optional)
+
+```bash
+pip install pytest-cov
+pytest test_main.py --cov=main --cov-report=html
+```
+
+## Test Structure
+
+### Test Classes
+
+The test suite is organized into the following test classes:
+
+| Test Class | Tests | Description |
+|------------|-------|-------------|
+| `TestHealthEndpoint` | 1 | Health check endpoint |
+| `TestRootEndpoint` | 3 | Homepage and authentication UI |
+| `TestOmiToolsManifest` | 3 | Chat tools manifest validation |
+| `TestGetRepoForRequest` | 3 | Repository selection logic |
+| `TestSetupEndpoint` | 2 | Setup completion checks |
+| `TestUpdateRepoEndpoint` | 2 | Repository update functionality |
+| `TestRefreshReposEndpoint` | 2 | Repository list refresh |
+| `TestCreateIssueTool` | 4 | Issue creation via chat |
+| `TestListReposTool` | 2 | Repository listing |
+| `TestListIssuesTool` | 2 | Issue listing |
+| `TestGetIssueTool` | 2 | Get issue details |
+| `TestAddCommentTool` | 2 | Add comments to issues |
+| `TestListLabelsTool` | 1 | List repository labels |
+| `TestAuthEndpoints` | 2 | OAuth authentication flow |
+| `TestAnthropicKeyEndpoints` | 2 | API key management |
+
+**Total: 33 tests**
+
+### Key Features Tested
+

+- ✅ `list_issues` - List repository issues
+- ✅ `get_issue` - Get issue details
+- ✅ `add_comment` - Add comments to issues
+- ✅ `list_labels` - List repository labels
+
+#### 2. Authentication
+- ✅ OAuth flow initiation
+- ✅ Callback handling
+- ✅ User authentication checks
+- ✅ Error handling for missing credentials
+
+#### 3. Repository Management
+- ✅ Default repository selection
+- ✅ Repository override via parameters
+- ✅ Repository list refresh
+- ✅ Error handling for missing repositories
+
+#### 4. API Key Management
+- ✅ Save Anthropic API key
+- ✅ Delete Anthropic API key
+- ✅ Key validation
+
+#### 5. Error Handling
+- ✅ Missing required parameters
+- ✅ Unauthenticated users
+- ✅ Invalid requests
+- ✅ GitHub API errors
+
+## Test Coverage
+
+Current test coverage includes:
+
+- **Endpoints**: All public API endpoints
+- **Chat Tools**: All 7 chat tools defined in manifest
+- **Authentication**: OAuth flow and session management
+- **Validation**: Input validation for all tools
+- **Error Cases**: Common error scenarios
+
+## Test Data
+
+Tests use mock objects and fixtures:
+
+```python
+@pytest.fixture
+def mock_user():
+    """Mock authenticated user with repositories"""
+    return {
+        "uid": "test-user-123",
+        "access_token": "mock_token_123",
+        "github_username": "testuser",
+        "selected_repo": "testuser/test-repo",
+        "available_repos": [...]
+    }
+```
+
+## Environment Setup
+
+Tests automatically set up required environment variables:
+
+- `OPENAI_API_KEY` - Mock OpenAI API key
+- `GITHUB_CLIENT_ID` - Mock GitHub OAuth client ID
+- `GITHUB_CLIENT_SECRET` - Mock GitHub OAuth client secret
+
+These are set to dummy values for testing purposes.
+
+## Continuous Integration
+
+To integrate with CI/CD pipelines (GitHub Actions, etc.):
+
+```yaml
+# .github/workflows/test.yml
+name: Run Tests
+
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      - name: Set up Python
+        uses: actions/setup-python@v2
+        with:
+          python-version: '3.10'
+      - name: Install dependencies
+        run: pip install -r requirements.txt
+      - name: Run tests
+        run: pytest test_main.py -v
+```
+
+## Adding New Tests
+
+When adding new features, follow this pattern:
+
+```python
+class TestNewFeature:
+    """Tests for new feature."""
+    
+    @patch('main.some_dependency')
+    def test_feature_success(self, mock_dep, client):
+        """Test successful feature execution."""
+        mock_dep.return_value = expected_value
+        
+        response = client.post("/endpoint", json={...})
+        assert response.status_code == 200
+        assert "expected" in response.json()
+    
+    def test_feature_error(self, client):
+        """Test error handling."""
+        response = client.post("/endpoint", json={})
+        assert response.status_code == 200
+        assert response.json().get("error") is not None
+```
+
+## Test Results
+
+All 33 tests pass successfully:
+
+```
+============================= test session starts ==============================
+test_main.py::TestHealthEndpoint::test_health_check PASSED               [  3%]
+test_main.py::TestRootEndpoint::test_root_without_uid PASSED             [  6%]
+[... 31 more tests ...]
+============================== 33 passed in 0.61s ===============================
+```
+
+## Troubleshooting
+
+### Import Errors
+
+If you see `ModuleNotFoundError`, ensure all dependencies are installed:
+
+```bash
+pip install -r requirements.txt
+```
+
+### Environment Variable Errors
+
+Tests should automatically set dummy environment variables. If you see errors about missing API keys, check that `test_main.py` sets them before importing `main`.
+
+### Mock Failures
+
+If mocks aren't working correctly, ensure you're patching the correct path:
+
+```python
+# Correct: Patch where it's used
+@patch('main.SimpleUserStorage.get_user')
+
+# Incorrect: Patching the original definition
+@patch('simple_storage.SimpleUserStorage.get_user')
+```
+
+## Future Improvements
+
+Potential enhancements to the test suite:
+
+- [ ] Integration tests with real GitHub API (using test tokens)
+- [ ] End-to-end tests for complete workflows
+- [ ] Performance/load testing
+- [ ] Test coverage reporting in CI
+- [ ] Mutation testing for test quality validation
+
+## Contributing
+
+When contributing new tests:
+
+1. Follow existing naming conventions
+2. Use descriptive test names: `test_<feature>_<scenario>`
+3. Add docstrings explaining what each test validates
+4. Group related tests in classes
+5. Mock external dependencies (GitHub API, OpenAI, etc.)
+6. Ensure tests are independent and can run in any order
