From 00fbe7f6add0ac58556e9fe3354d300294e6c3ef Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Thu, 10 Mar 2022 17:18:14 +0000 Subject: [PATCH] tests: expand the migration precopy helper to support failures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The migration precopy testing helper function always expects the migration to run to a completion state. There will be test scenarios for TLS where expect either the client or server to fail the migration. This expands the helper to cope with these scenarios. Signed-off-by: Daniel P.
