201 |
202 | ## Progress Tracking & Resume
203 |
204 | The loader automatically saves progress to a checkpoint file:
205 |
206 | ```json
207 | {
208 | "timestamp": "2024-01-15T10:30:00",
209 | "total_symbols": 100,
210 | "processed_symbols": 75,
211 | "successful_symbols": 73,
212 | "completed_symbols": ["AAPL", "MSFT", ...],
213 | "failed_symbols": ["BADTICKER", "ANOTHERBAD"],
214 | "errors": [...],
215 | "elapsed_time": 3600
216 | }
217 | ```
218 |
219 | To resume an interrupted load:
220 | ```bash
221 | python scripts/load_tiingo_data.py --resume --checkpoint-file load_progress.json
222 | ```
223 |
224 | ## Error Handling
225 |
226 | ### Automatic Retry Logic
227 | - **Exponential Backoff**: 1s, 2s, 4s delays between retries
228 | - **Rate Limit Handling**: Automatic delays when rate limited
229 | - **Connection Errors**: Automatic retry with timeout handling
230 |
231 | ### Error Reporting
232 | - **Detailed Logging**: All errors logged with context
233 | - **Error Tracking**: Failed symbols tracked in checkpoint
234 | - **Graceful Degradation**: Continue processing other symbols on individual failures
235 |
236 | ## Performance Optimization
237 |
238 | ### Database Optimizations
239 | - **Bulk Inserts**: Use PostgreSQL's UPSERT for efficiency
240 | - **Connection Pooling**: Reuse database connections
241 | - **Batch Processing**: Process multiple symbols together
242 | - **Index Creation**: Automatically create performance indexes
243 |
244 | ### Memory Management
245 | - **Streaming Processing**: Process data in chunks to minimize memory usage
246 | - **Garbage Collection**: Explicit cleanup of large DataFrames
247 | - **Connection Limits**: Prevent connection exhaustion
248 |
249 | ### Monitoring
250 | ```bash
251 | # Monitor progress in real-time
252 | tail -f tiingo_data_loader.log
253 |
254 | # Check database stats
255 | python scripts/load_tiingo_data.py --database-stats
256 |
257 | # Monitor system resources
258 | htop # CPU and memory usage
259 | iotop # Disk I/O usage
260 | ```
261 |
262 | ## Examples and Testing
263 |
264 | ### Interactive Examples
265 | ```bash
266 | # Run interactive examples
267 | python scripts/load_example.py
268 | ```
269 |
270 | The example script provides:
271 | 1. Load sample stocks (5 symbols)
272 | 2. Load sector stocks (technology)
273 | 3. Resume interrupted load demonstration
274 | 4. Database statistics viewer
275 |
276 | ### Testing Different Configurations
277 | ```bash
278 | # Test with small dataset
279 | python scripts/load_tiingo_data.py --symbols AAPL,MSFT --years 1 --batch-size 10
280 |
281 | # Test screening only (no new data)
282 | python scripts/load_tiingo_data.py --symbols AAPL --years 0.1 --run-screening
283 |
284 | # Test resume functionality
285 | python scripts/load_tiingo_data.py --symbols AAPL,MSFT,GOOGL,AMZN,TSLA --batch-size 2
286 | # Interrupt with Ctrl+C, then resume:
287 | python scripts/load_tiingo_data.py --resume
288 | ```
289 |
290 | ## Troubleshooting
291 |
292 | ### Common Issues
293 |
294 | #### 1. API Token Issues
295 | ```bash
296 | # Check if token is set
297 | echo $TIINGO_API_TOKEN
298 |
299 | # Test API access
300 | curl -H "Authorization: Token $TIINGO_API_TOKEN" \
301 | "https://api.tiingo.com/tiingo/daily/AAPL"
302 | ```
303 |
304 | #### 2. Database Connection Issues
305 | ```bash
306 | # Check database URL
307 | echo $DATABASE_URL
308 |
309 | # Test database connection
310 | python -c "from maverick_mcp.data.models import SessionLocal; print('DB OK')"
311 | ```
312 |
313 | #### 3. Rate Limiting
314 | If you're getting rate limited frequently:
315 | - Reduce `--max-concurrent` (default: 5)
316 | - Increase `--batch-size` to reduce total requests
317 | - Consider upgrading to Tiingo's paid plan
318 |
319 | #### 4. Memory Issues
320 | For large loads:
321 | - Reduce `--batch-size`
322 | - Reduce `--max-concurrent`
323 | - Monitor memory usage with `htop`
324 |
325 | #### 5. Checkpoint Corruption
326 | ```bash
327 | # Remove corrupted checkpoint
328 | rm load_progress.json
329 |
330 | # Start fresh
331 | python scripts/load_tiingo_data.py --symbols AAPL,MSFT --no-checkpoint
332 | ```
333 |
334 | ### Performance Benchmarks
335 |
336 | Typical performance on modern hardware:
337 | - **Small Load (10 symbols, 1 year)**: 2-3 minutes
338 | - **Medium Load (100 symbols, 2 years)**: 15-20 minutes
339 | - **Large Load (500 symbols, 2 years)**: 1-2 hours
340 | - **Full Load (3000+ symbols, 2 years)**: 6-12 hours
341 |

1 | # ExaSearch Research Integration Testing Strategy
2 |
3 | This document outlines the comprehensive testing strategy for validating the ExaSearch integration with the MaverickMCP research agent architecture.
4 |
5 | ## Overview
6 |
7 | The testing strategy covers all aspects of the research system with ExaSearch provider:
8 | - **DeepResearchAgent** orchestration with ExaSearch integration
9 | - **Specialized Subagents** (Fundamental, Technical, Sentiment, Competitive)
10 | - **Parallel Research Orchestration** and task distribution
11 | - **Timeout Handling** and circuit breaker patterns
12 | - **MCP Tool Integration** via research router endpoints
13 | - **Performance Benchmarking** across research depths and configurations
14 |
15 | ## Test Architecture
16 |
17 | ### Test Categories
18 |
19 | 1. **Unit Tests** (`pytest -m unit`)
20 | - Individual component testing in isolation
21 | - Mock external dependencies
22 | - Fast execution (< 30 seconds total)
23 | - No external API calls
24 |
25 | 2. **Integration Tests** (`pytest -m integration`)
26 | - End-to-end workflow testing
27 | - Real ExaSearch API integration
28 | - Multi-component interaction validation
29 | - Requires `EXA_API_KEY` environment variable
30 |
31 | 3. **Performance Tests** (`pytest -m slow`)
32 | - Benchmark different research depths
33 | - Parallel vs sequential execution comparison
34 | - Memory usage and timeout resilience
35 | - Longer execution times (2-5 minutes)
36 |
37 | 4. **Benchmark Suite** (`scripts/benchmark_exa_research.py`)
38 | - Comprehensive performance analysis
39 | - Cross-configuration comparison
40 | - Detailed metrics and reporting
41 | - Production-ready performance validation
42 |

383 | ```
384 |
385 | 2. **Import Errors**
386 | ```
387 | ImportError: No module named 'exa_py'
388 | Solution: Install dependencies with `uv sync` or `pip install -e .`
389 | ```
390 |
391 | 3. **Timeout Failures**
392 | ```
393 | Error: Research operation timed out
394 | Solution: Check network connection or reduce research scope
395 | ```
396 |
397 | 4. **Memory Issues**
398 | ```
399 | Error: Memory usage exceeded limits
400 | Solution: Reduce parallel agents or test data size
401 | ```
402 |
403 | ### Debug Mode

442 | ## Continuous Integration
443 |
444 | ### CI/CD Integration
445 |
446 | The test suite is designed for CI/CD integration:
447 |
448 | ```yaml
449 | # Example GitHub Actions workflow
450 | - name: Run ExaSearch Tests
451 | env:
452 | EXA_API_KEY: ${{ secrets.EXA_API_KEY }}
453 | run: |
454 | python scripts/run_exa_tests.py --unit
455 | python scripts/run_exa_tests.py --integration
456 | python scripts/benchmark_exa_research.py --quick
457 | ```
458 |
459 | ### Test Markers for CI
460 |
461 | Use pytest markers for selective testing:
462 |
463 | ```bash
464 | # Fast tests only (for PR validation)
465 | pytest -m "not slow and not external"
466 |
467 | # Full test suite (for main branch)
468 | pytest -m "not external" --maxfail=5
469 |
470 | # External API tests (nightly/weekly)
471 | pytest -m external
472 | ```
473 |
474 | ## Maintenance and Updates
475 |
476 | ### Adding New Tests
477 |
478 | 1. **Extend existing test classes** for related functionality
479 | 2. **Follow naming conventions**: `test_[component]_[scenario]`
480 | 3. **Use appropriate markers**: `@pytest.mark.unit`, `@pytest.mark.integration`
481 | 4. **Mock external dependencies** in unit tests
482 | 5. **Include error scenarios** and edge cases
483 |
484 | ### Updating Test Data
485 |
486 | 1. **Mock responses** should reflect real ExaSearch API responses
487 | 2. **Test queries** should cover different complexity levels
488 | 3. **Performance baselines** should be updated as system improves
489 | 4. **Error scenarios** should match actual failure modes
490 |
491 | ### Performance Regression Detection
492 |
493 | 1. **Baseline metrics** stored in benchmark results
494 | 2. **Automated comparison** against previous runs
495 | 3. **Alert thresholds** for performance degradation
496 | 4. **Regular benchmark execution** in CI/CD
497 |
498 | ## Conclusion
499 |
500 | This comprehensive testing strategy ensures the ExaSearch integration is thoroughly validated across all dimensions:
501 |
502 | - ✅ **Functional Correctness**: All components work as designed
503 | - ⚡ **Performance Characteristics**: System meets timing requirements
504 | - 🛡️ **Error Resilience**: Graceful handling of failures and edge cases
505 | - 🔗 **Integration Quality**: Seamless operation across component boundaries
506 | - 📊 **Monitoring Capability**: Detailed metrics and reporting for ongoing maintenance
507 |
