- Move tests to use std::env::temp_dir() instead of ./tmp
- Generate test certificates on-demand with openssl
- Create isolated test environments with automatic cleanup
- Add comprehensive config validation integration tests
- Temporarily simplify rate limiting test (complex TLS testing deferred)
- Tests now work out-of-the-box for fresh repository clones
- Run tests sequentially to avoid stderr mixing in parallel execution
- Update README.md to mention Python 3 requirement for integration tests
- Make rate limiting test skip gracefully if Python 3 is not available
- Move and rename test helper script to tests/gemini_test_client.py
- Update test to use new script path
- Improve test documentation and error handling
- Test concurrent requests with max_concurrent_requests = 1
- Verify 1 successful response and 4 rate limited responses
- Use python test script for TLS Gemini requests
- Test runs with 3-second processing delay for proper concurrency
- Validates rate limiting behavior end-to-end
