From 282d9c67872ec2b992825c941e02a5cb3fbf577d Mon Sep 17 00:00:00 2001 From: Nessar Date: Sat, 17 Oct 2026 16:10:29 +0200 Subject: [PATCH] fix: report line-only coverage honestly and tighten Bun test helpers The generated HTML and Cobertura reports no longer show unmeasured branch and function coverage as 100%. Poll and waitFor deadlines use performance.now so frozen dates cannot make them loop forever, the malformed-configuration test covers undefined again next to the empty array, compose health checks honor PORT, and the migration spec lists only what is still open.
