From 95300f203f3249ffb7a08222dc4d8106c5a6ceeb Mon Sep 17 00:00:00 2001 From: Kory Maincent Date: Tue, 4 May 2021 19:31:23 +0200 Subject: pytest: add sandbox test for "extension" command This commit extends the sandbox to implement a dummy extension_board_scan() function and enables the extension command in the sandbox configuration. It then adds a test that checks the proper functionality of the extension command by applying two Device Tree overlays to the sandbox Device Tree.
