From d864756e8734b22a9e7825c0fa46c7459a7ad105 Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Mon, 9 Oct 2023 15:43:26 -0300 Subject: [PATCH] tests/qtest/migration: Add a test for the analyze-migration script Add a smoke test that migrates to a file and gives it to the script. It should catch the most annoying errors such as changes in the ram flags. After code has been merged it becomes way harder to figure out what is causing the script to fail, the person making the change is the most likely to know right away what the problem is.
