# Test Master Checkpoint: Issue #41 - DeepSeek API Support
|
|
|
|
**Agent**: test-master
|
|
**Date**: 2025-12-26
|
|
**Status**: RED phase complete - 43 tests created
|
|
|
|
## Summary
|
|
|
|
Created comprehensive test suite for Issue #41 - DeepSeek API Support and Alternative Embedding Models.
|
|
|
|
## Test Coverage
|
|
|
|
### Total: 43 tests across 8 test classes
|
|
|
|
1. **TestDeepSeekInitialization** (4 tests)
|
|
- DeepSeek provider uses ChatOpenAI
|
|
- Correct base_url configuration
|
|
- Custom headers for attribution
|
|
- Both LLM models initialized
|
|
|
|
2. **TestAPIKeyHandling** (4 tests)
|
|
- Missing API key error handling
|
|
- Valid API key acceptance
|
|
- Empty API key rejection
|
|
- OpenAI key not used for DeepSeek
|
|
|
|
3. **TestModelFormatValidation** (3 tests)
|
|
- deepseek-chat format
|
|
- deepseek-reasoner format
|
|
- Alternative model names
|
|
|
|
4. **TestEmbeddingFallback** (6 tests)
|
|
- OpenAI embeddings when key available
|
|
- HuggingFace fallback without OpenAI
|
|
- Memory disabled when no backend
|
|
- HuggingFace embedding dimensions (384)
|
|
- Graceful degradation messages
|
|
- OpenAI priority over HuggingFace
|
|
|
|
5. **TestConfiguration** (6 tests)
|
|
- Case-insensitive provider names
|
|
- Default DeepSeek models
|
|
- Custom backend URL
|
|
- Empty backend URL handling
|
|
- None backend URL handling
|
|
|
|
6. **TestErrorHandling** (5 tests)
|
|
- Network error handling
|
|
- Rate limit error handling
|
|
- Invalid model error
|
|
- Invalid provider error
|
|
- HuggingFace import error
|
|
|
|
7. **TestHuggingFaceIntegration** (5 tests)
|
|
- SentenceTransformer initialization
|
|
- Encode method usage
|
|
- Batch embedding
|
|
- Model caching
|
|
- Embedding normalization
|
|
|
|
8. **TestEdgeCases** (7 tests)
|
|
- Empty model names
|
|
- Special characters in models
|
|
- URL trailing slashes
|
|
- Empty collection queries
|
|
- Zero matches requested
|
|
- Very long text embedding
|
|
- Unicode text embedding
|
|
- Embedding fallback with partial failure
|
|
|
|
9. **TestChromaDBCollectionHandling** (3 tests)
|
|
- get_or_create_collection usage
|
|
- Idempotent collection creation
|
|
- Multiple collections coexist
|
|
|
|
## Test Results (RED Phase)
|
|
|
|
- **Failed**: 23 tests (expected - no implementation yet)
|
|
- **Errors**: 9 tests (expected - SentenceTransformer not imported yet)
|
|
- **Passed**: 11 tests (edge cases that don't depend on DeepSeek implementation)
|
|
|
|
### Key Failures (Expected):
|
|
- "Unsupported LLM provider: deepseek" - Main implementation needed
|
|
- "AttributeError: 'SentenceTransformer'" - HuggingFace fallback not implemented
|
|
|
|
## Implementation Requirements
|
|
|
|
Based on test expectations:
|
|
|
|
1. **trading_graph.py**: Add DeepSeek provider case
|
|
- Use ChatOpenAI with base_url
|
|
- Require DEEPSEEK_API_KEY
|
|
- Set custom headers (optional)
|
|
- Models: deepseek-chat, deepseek-reasoner
|
|
|
|
2. **memory.py**: Add embedding fallback chain
|
|
- Try OpenAI embeddings first
|
|
- Fall back to HuggingFace SentenceTransformer
|
|
- Use all-MiniLM-L6-v2 model (384 dims)
|
|
- Disable memory gracefully if both fail
|
|
|
|
## Next Steps
|
|
|
|
1. Implement DeepSeek provider in trading_graph.py
|
|
2. Implement HuggingFace embedding fallback in memory.py
|
|
3. Run tests to verify GREEN phase
|
|
4. Refactor if needed
