From 246f48fd2ba88e4edf3e4b4ebd9ddc3ac6043c16 Mon Sep 17 00:00:00 2001 From: Aditya Chhabra Date: Wed, 11 Mar 2026 08:46:12 +0000 Subject: [PATCH] fix(test): align TDD bug #647 assertions with expected-fail inversion flow Updated Behave and Robot TDD tests for issue #648 to assert correct behavior while tagged with tdd_expected_fail, so listener/hook inversion works as intended. Also hardened test isolation and reliability by adding in-memory engine cache cleanup, per-run plan IDs, stricter assertion semantics, reduced Robot timeout, and an issue-resolution markdown response for Coree review comments.
