From b50438aff3b23f3395c271ec4c4540e8c3bc6986 Mon Sep 17 00:00:00 2001 From: Warm Beer Date: Wed, 28 Jan 2026 10:28:01 +0100 Subject: [PATCH 1/2] refactor: add automatic test isolation for e2e testnets - Generate random ports (20000-60000) for each test run - Create unique temp directories with random suffix - Extract magic numbers into named constants - Move imports to module level per coding standards - Fix dual-stack IPv6 binding issues This prevents test pollution when running tests in parallel.
