From e6dc3ab2bfcf45db4d303aef0d9aba9df8b1911b Mon Sep 17 00:00:00 2001 From: royavrahami Date: Mon, 1 Jun 2026 14:34:02 +0300 Subject: [PATCH] test: raise coverage 48% -> 64% (collectors, scheduler, digest) Mirror of the QA agent coverage work. Add tests for the previously-untested I/O and orchestration layers (network/DB/LLM mocked), taking real coverage from 48% to 64% (97 tests, up from 78): - Arxiv collector: collect_all parses + persists papers, dedup, static helpers. - GitHub collector: trending HTML scrape + search-API JSON path, auth headers. - Scheduler: AgentScheduler registers the job and starts (no blocking loop). - Daily digest agent: enrichment/statistics builders + date formatting. Raise pytest --cov-fail-under 45 -> 60 to lock in the gain.
