From e1c4f57c353dff6ff15b62331b10f0b1f661151b Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 6 Apr 2022 15:29:06 +1000 Subject: [PATCH] runtime: Don't abuse MockStorageRootPath() for factory tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A number of unit tests under virtcontainers/factory use MockStorageRootPath() as a general purpose temporary directory. This doesn't make sense: the mockfs driver isn't even in use here since we only call EnableMockTesting for the pase virtcontainers package, not the subpackages. Instead use t.TempDir() which is for exactly this purpose. As a bonus it also handles the cleanup, so we don't need MockStorageDestroy any more.
