Story MP-010: Develop Unit Tests for Adapters, Stages, and Exporter

Description:
Build comprehensive unit test coverage for adapters, processing stages, and the export system. Focus on reliability and reproducibility using mock API responses.

Tasks:

• Configure pytest environment and test discovery under /tests/
• Write adapter tests using mock responses (YFinance, AlphaVantage, FMP)
• Add stage tests for NaNProcessing, Deduplication, and QualityAssurance
• Test exporter output schema and unique key deduplication logic
• Set coverage goal ≥ 80% and integrate with CI pipeline

Acceptance Criteria:

• All critical modules pass unit tests
• Mock APIs simulate expected responses correctly
• Test coverage ≥ 80%
• CI pipeline runs tests automatically on push

Estimation: 3 days
Dependencies: MP-004, MP-007
Status: Planned
