From 44da35faf68434a0ef4597dce81dfe01b77eee14 Mon Sep 17 00:00:00 2001 From: Ping Qiu Date: Mon, 2 Mar 2026 15:05:29 -0800 Subject: [PATCH] test: add integration test infrastructure for blockvol iSCSI Test harness for running blockvol iSCSI tests on WSL2 and remote nodes (m01/M02). Includes Node (SSH/local exec), ISCSIClient (discover/login/ logout), WeedTarget (weed volume server lifecycle), and test suites for smoke, stress, crash recovery, chaos, perf benchmarks, and apps (fio/dd).
