From 78aa0427fc0e9ce27fbd40c6dc3ace0d89d9c62c Mon Sep 17 00:00:00 2001 From: anandgupta42 Date: Wed, 4 Mar 2026 22:28:03 -0800 Subject: [PATCH] test: add E2E tests for npm install pipeline Add test suite exercising the three key install components (postinstall script, bin wrapper, publish output) by building fake npm layouts in temp dirs and running the real scripts as subprocesses. Catches the class of failure where an expired npm token causes optionalDependencies to fail silently, leaving the postinstall script to crash. 24 tests across 4 files, no build step or network access required.
