Subject: [Buildroot] [git commit] support/testing: add fs tests
Date: Sun, 7 May 2017 22:04:54 +0200	[thread overview]
Message-ID: <20170507200503.01FB7827D5@busybox.osuosl.org> (raw)

commit: https://git.buildroot.net/buildroot/commit/?id=bf4a6490e4ee70f0a46e588602995ba34e6c872a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This commit adds a number of test cases for various filesystem formats:
ext2/3/4, iso9660, jffs2, squashfs, ubi/ubifs and yaffs2. All of them
except yaffs2 are runtime tested. The iso9660 set of test cases is
particularly rich, testing the proper operation of the iso9660 support
with all of grub, grub2 and isolinux.
