From e20b70c2e64b1f5660c6db4acce9d23e79693ac4 Mon Sep 17 00:00:00 2001 From: Ed Santiago Date: Mon, 5 Feb 2024 07:56:47 -0700 Subject: [PATCH] Upgrade tests: reenable, but revamped No longer bother testing any 2.x or 3.x. Only 4.1 and above. Remove all CNI-related code. CNI is gone. Add DatabaseBackend tests, confirming that we can handle both boltdb and sqlite. Require BATS >= 1.8.0, and use "run -0" to do exit-status checks. Update docs.
