From 351255f5f0de0ebd8ff4a6e522a6bb73b9400f37 Mon Sep 17 00:00:00 2001 From: Hal Spang Date: Tue, 20 May 2025 22:28:39 -0700 Subject: [PATCH 1/3] Fix integration test retry extension The integration tests were using a retry extension that was eating exceptions and hiding failures. This commit updates the extension to retry and still report failed tests.
