From 048491b6d7e478dc6442091f34f2e805a4a2d147 Mon Sep 17 00:00:00 2001 From: Daniel Han Date: Thu, 7 May 2026 08:56:02 +0000 Subject: [PATCH] CI(ui): filter benign pageerrors before gating on the count The end-of-test pageerror gate was firing on transient backend 4xx responses (422 from /v1/chat/completions when the rapid-fire chat turns race the previous turn's stream) and on Shutdown-induced network errors. Those are NOT frontend regressions; they are network-layer responses the page faithfully bubbles up. Filter out: - "Request failed (422)" -- transient backend rejection - "Failed to fetch" / "NetworkError" -- post-Shutdown noise - "Load failed" -- WebKit's network-error wording - "At least one non-system message is required" -- backend's explicit rejection of malformed message arrays Real frontend regressions (TypeError, ReferenceError, null deref) still gate. --- tests/studio/playwright_chat_ui.py | 30 ++++++++++++++++++++++++++++-- 1 file changed, 28 insertions(+), 2 deletions(-) diff --git a/tests/studio/playwright_chat_ui.py b/tests/studio/playwright_chat_ui.py index 7981a92df5..800ad4f714 100644 --- a/tests/studio/playwright_chat_ui.py +++ b/tests/studio/playwright_chat_ui.py @@ -1112,9 +1112,35 @@ with sync_playwright() as p: except urllib.error.URLError as exc: info(f"OK /api/health unreachable: {exc!r}") + # Some pageerrors are benign in this test: + # - "Request failed (422)": the OpenAI-compatible chat-completions + # endpoint rejects rapid-fire/malformed requests with 422.
