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>] Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>lime2-spi
