From 9e33824449903981fd4b8852941a96ecfd157847 Mon Sep 17 00:00:00 2001 From: claude Date: Sat, 23 May 2026 01:26:10 +0000 Subject: [PATCH] Add comprehensive user-test tier for REST + MCP surfaces Adds tests/user/ with end-to-end subprocess-driven coverage: - test_rest_full.py: every Flask endpoint, response envelopes, snapshot lifecycle, observe diff, Prometheus metrics. - test_mcp_protocol.py: NDJSON framing, all 49 MCP tools smoked, stdout purity (logs to stderr). - test_predicates_full.py: all 9 assert_state predicate kinds plus AND. - test_element_actions_full.py: focus/set_value/invoke/select/hover/drag/ key_into/clear_text/propose-confirm flow. - test_scenarios_user.py, test_trace_replay.py, test_ascii_render_snapshot.py, test_budget_redaction_audit.py, test_setup_config_live.py. - Optional-deps tests (test_ocr_real_tesseract.py, test_vlm_real_ollama.py, test_ollama_setup_live.py, test_xvfb_live.py) skip gracefully without the underlying binaries / daemons. Adds pytest.ini with markers (user, slow_llm, slow_vlm, needs_display, needs_tesseract). Updates ci.yml to run the new tier alongside regression.
