This means that configuration backend tests no longer use stubs and (mostly) avoid internal dependencies in the tests. Instead of stubs and mock-fs, the tests use [testfs](https://github.com/balena-io-modules/mocha-pod#working-with-the-filesystem) which allows working with a real filesystem and ensuring everything is re-set between tests. This is the last change needed in order to be able to merge #1971. Here is the list of changes - [x] Migrate splash image backend tests - [x] Migrate extlinux backend tests - [x] Migrate config.txt backend tests - [x] Migrate extra-uenv config tests - [x] Migrate odmdata config tests - [x] Migrate config utils tests - [x] Migrate device-config tests Change-type: patch
