 # Session Log
 
+## Session: 2025-03-20 - API Testing Implementation
+
+### Overview
+Created a comprehensive testing framework for the sim-search API, including automated tests with pytest, a test runner script, and a manual testing script using curl commands.
+
+### Key Activities
+1. **Created Automated API Tests**:
+   - Implemented `test_api.py` with pytest to test all API endpoints
+   - Created tests for authentication, query processing, search execution, and report generation
+   - Set up test fixtures for database initialization and user authentication
+   - Implemented test database isolation to avoid affecting production data
+
+2. **Developed Test Runner Script**:
+   - Created `run_tests.py` to simplify running the tests
+   - Added command-line options for verbosity, coverage reporting, and test selection
+   - Implemented clear output formatting for test results
+
+3. **Created Manual Testing Script**:
+   - Implemented `test_api_curl.sh` for manual testing with curl commands
+   - Added tests for all API endpoints with proper authentication
+   - Implemented colorized output for better readability
+   - Added error handling and dependency checks between tests
+
+4. **Added Test Documentation**:
+   - Created a README.md file for the tests directory
+   - Documented how to run the tests using different methods
+   - Added troubleshooting information for common issues
+
+### Insights
+- The FastAPI TestClient provides a convenient way to test API endpoints without starting a server
+- Using a separate test database ensures that tests don't affect production data
+- Pytest fixtures are useful for setting up and tearing down test environments
+- Manual testing with curl commands is useful for debugging and understanding the API
+
+### Challenges
+- Ensuring proper authentication for all API endpoints
+- Managing dependencies between tests (e.g., needing a search ID to generate a report)
+- Setting up a clean test environment for each test run
+- Handling asynchronous operations in tests
+
+### Next Steps
+1. Run the tests to verify that the API is working correctly
+2. Fix any issues found during testing
+3. Add more specific tests for edge cases and error handling
+4. Integrate the tests into a CI/CD pipeline
+5. Add performance tests for the API
+6. Consider adding integration tests with the frontend
