From e8c53fcc5177a92d886ebf5957e4747add6e88e5 Mon Sep 17 00:00:00 2001 From: Vinayak Papnoi Date: Fri, 22 Jun 2018 17:37:44 +0530 Subject: Quota : test case with creation of file larger than quota limit If a limit is set and a file of size larger than limit is created then the file creation will stop when it will reach the limit. - Enable Quota - Create a directory from mount point - Set a limit of 10 MB on the directory - Set Quota soft-timeout and hard-timeout to 0 seconds - Create a file of size larger than the Quota limit eg. 20 MB file - Perform Quota list operation to check if all the fields are appropriate such as hard_limit, available_space, sl_exceeded, hl_execeeded, etc. Change-Id: I44d7e23e60589cbe022735e9b4b5f3bfd1b7458e Signed-off-by: Vinayak Papnoi --- .../quota/test_quota_file_larger_than_limit.py | 180 +++++++++++++++++++++ 1 file changed, 180 insertions(+) create mode 100644 tests/functional/quota/test_quota_file_larger_than_limit.py diff --git a/tests/functional/quota/test_quota_file_larger_than_limit.py b/tests/functional/quota/test_quota_file_larger_than_limit.py new file mode 100644 index 000000000..d354f7155 --- /dev/null +++ b/tests/functional/quota/test_quota_file_larger_than_limit.py @@ -0,0 +1,180 @@ +# Copyright (C) 2017-2018 Red Hat, Inc. +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2 of the License, or +# any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
