Summary

Implements Issue #18 — Integration test suite for the full audio-to-task pipeline. Connects programmatically-generated audio PCM WAV fixtures to speech-to-text engines, transcript batch writers, scheduled task extractors, rule-based NLP classifiers, and database tables.

Changes

Integration Testing

• Created tests/integration/test_pipeline.py implementing:
  • Synthetic sine-wave audio PCM WAV generation for test inputs.
  • Chunked reading of WAV waveforms mapped to float32 numpy arrays.
  • Mock vosk.KaldiRecognizer class tracking indices globally to return exactly 5 representative speech sentences:
    1. "I must immediately buy groceries today." (Urgent + Important)
    2. "We need to plan a strategic roadmap." (Important + Not Urgent)
    3. "I need to tell John to fix the website right now." (Delegate + Urgent)
    4. "I should maybe write a funny story eventually." (Low Importance + Not Urgent)
    5. "We have to urgently write the report before noon." (Urgent + Important)
  • Integration of TranscriptWriter to write speech segments to database.
  • Integration of ExtractionScheduler running _run_extraction_cycle() headlessly to extract task lists and map them.
  • Assertions verifying correct database record inserts in transcripts, tasks, and matrix_entries tables, ensuring check constraint mapping values match the expected target quadrants (urgent_important, important_not_urgent, urgent_not_important, neither).

Configuration & Tooling

• Updated Makefile test target to run the entire test suite pytest tests/ -v.
• Updated GitHub Actions CI workflow .github/workflows/ci.yml to run the entire test suite on Linux/Windows matrices.

Verification Results

• All integration and unit tests pass locally:

  tests\integration\test_pipeline.py .                                     [  0%]
  ...
  ============================ 151 passed in 14.12s =============================
  Required test coverage of 80% reached. Total coverage: 83.63%
  

• No memory leaks, resource warnings (connection is cleanly yielded and closed), or display errors.

Closes #18
