Context: The port's graceful-failure contract was implicit in the way each strategy returns None/[] on malformed input, but without tests it was an accidental property that could regress silently. Codify it. Two invariants, each backed by a fixture: 1. Junk email → empty list, never raise. `unparseable.eml` is a pure-marketing IE newsletter with no order data. All three strategies try and fail; parse_invest_engine_email returns []. No exception leaks. 2. Partial HTML email → intact orders only. `html_partial_match.eml` has two nested summary tables: one with a valid VUAG order, one that is missing both the ticker and "Bought N @ £P" rows (simulates IE dropping content mid-render). The parser returns just the VUAG order. No implementation change needed — the behaviour existed as a side effect of _try_html_summary_table returning None on missing fields. These tests lock it down so future refactors can't quietly break it. Test plan: poetry run pytest tests/providers/parsers/ -q → 8 passed in 0.19s poetry run mypy broker_sync/providers/parsers/invest_engine.py tests/providers/parsers/test_invest_engine.py → clean poetry run ruff check broker_sync/providers/parsers/invest_engine.py tests/providers/parsers/test_invest_engine.py → All checks passed! poetry run yapf --diff → clean (no diff) Manual verification: - Load unparseable.eml → parse returns []. - Load html_partial_match.eml → parse returns exactly 1 activity (VUAG). |
