[U-Boot] [PATCH v3 23/26] test/py: convert fs-test.sh to pytest
Akashi, Takahiro
takahiro.akashi at linaro.org
Tue Sep 11 06:59:19 UTC 2018
From: AKASHI Takahiro <takahiro.akashi at linaro.org>
In this commit, the same set of test cases as in test/fs/fs-test.sh
is provided using pytest framework.
Actually, fs-test.sh provides three variants:"sb" (sb command), "nonfs"
(fatxx and etc.) and "fs" (hostfs), and this patch currently supports
only "nonfs" variant; So it is not a replacement of fs-test.sh for now.
Simple usage:
$ py.test test/py/tests/test_fs [<other options>]
You may also specify filesystem types to be tested:
$ py.test test/py/tests/test_fs --fs-type fat32 [<other options>]
