From f6f15ebd9aac2c7cda1ed32228614791c6cb0ad9 Mon Sep 17 00:00:00 2001 From: Marc Mintel Date: Sat, 2 May 2026 22:10:57 +0200 Subject: [PATCH] =?UTF-8?q?test:=20expand=20LLM=20perception=20suite=20to?= =?UTF-8?q?=2080=20tests=20=E2=80=94=203=20new=20contracts?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CONTRACT 6: extract_json() — LLM Response Sanitizer (9 tests) Previously COMPLETELY untested. Every single LLM response in the entire system passes through this function. Tests: - Clean JSON, markdown fences (json+plain), thinking block purge - Text prefix before JSON, truncated JSON fuzzy recovery - Garbage/empty/None resilience CONTRACT 7: _visual_discovery Pre-Filters (8 tests) The guards INSIDE _visual_discovery() that run BEFORE the VLM ever sees the candidates. If they fail, the VLM gets garbage and hallucinates. Tests: - Area filter: tiny nodes (<200px²) and huge containers (>400000px²) - SystemUI filter: Android system elements, notifications, battery - Strict Button Guard: long text captions excluded for button intents - Grid Item Guard: non-grid elements excluded, fallthrough on no match - Author/Username Guard: nav tabs excluded for author intents CONTRACT 8: verify_success Structural Delta (8 tests) The post-click verification logic that decides if a click actually worked. Tests: - Toggle massive XML shift = navigation error (False) - Toggle small diff = success (True) - Toggle zero diff = inconclusive (None) - Follow success with 'Requested' marker (private accounts) - Follow success with German locale ('Abonniert') - View post with clips_viewer marker (Reels) - View post still on grid = inconclusive (None) - Semantic gate blocks wrong toggle element (caption != like button) --- tests/e2e/test_system_llm_perception.py | 365 ++++++++++++++++++++++++ 1 file changed, 365 insertions(+) diff --git a/tests/e2e/test_system_llm_perception.py b/tests/e2e/test_system_llm_perception.py index babe13d..47327aa 100644 --- a/tests/e2e/test_system_llm_perception.py +++ b/tests/e2e/test_system_llm_perception.py @@ -515,3 +515,368 @@ class TestActionMemoryLifecycle: "view a post", pre_click_xml="", post_click_xml=post_xml_success ) assert result is True + + +# ═══════════════════════════════════════════════════════════════════════ +# CONTRACT 6: extract_json() — LLM Response Sanitizer +# ═══════════════════════════════════════════════════════════════════════ +# +# EVERY LLM response passes through this function.
