+
+
+ mirror_tests is designed to check that yaffs behaves the same way as linux.
+ This is done by applying the same command to both linux and yaffs and
+ then checking the output of the functions.
+ The default place for creating linux files is direct/timothy_tests/mirror_tests/tests/
+ This directory is removed and is recreated at the beginning of each test,
+ However some of the files may be read only and cannot be deleted.
+ It is much better to remove this directory via the command line.
+
+ rm test/*;rmdir test/;./mirror_tests -n 100 -v
+
+Command line arguments
+ -yaffs_path [PATH] //sets the path for yaffs.
+ -linux_path [PATH] //sets the path for linux.
+ -p [NUMBER] //sets the print level for mirror_tests.
+ -v //verbose mode everything is printed
+ -q //quiet mode nothing is printed.
+ -n [number] //sets the number of random tests to run.
+ -s [number] //seeds rand with the number
+ -t [number] //sets yaffs_trace to the number
+ -clean //removes emfile and test dir
+
BUGS
- In yaffs having a pathname "yaffs2/tests//.." appears to create a file called ".." unstead of going back a directory.
+ NO Bugs.
