check to see if an error code is generated when there isn't an error.
Test_yaffs_[function of yaffs which is been tested]_[error trying to be generated]
The .c file needs to contain two functions.
- The first function needs to contain the code for the main test and will return -1 on a failure and 0 or greater on a success.
- The second function needs contain the code for cleaning up after the test. Cleaning up may include closing some open handles, recreating a file, ect.

This second function needs to return -1 on a failure and 0 or greater on success.
- The name of first function needs to be called the same as the file name (without the .c or .h)
- The second function's name needs be the same as the first function but with "_clean" added on the end.

- So if a test is been created for the yaffs function yaffs_fish() then create these files
- Test_yaffs_fish.c
- Contains int test_yaffs_fish(void); int test_yaffs_fish_clean(void);
- Test_yaffs_fish.h
+ So if a test is been created for the yaffs function yaffs_foo() then
+ create these files
+ test_yaffs_foo.c
+ Contains int test_yaffs_foo(void); int test_yaffs_foo_clean(void);
+ test_yaffs_foo.h
Which includes "lib.h", "yaffsfs.h" header files.
Next write the test code in these files then add these files to the Makefile.
- Add the name of the test files' object file (test_yaffs_fish.o ) to the TESTFILES tag around line 50 of the Makefile.

Now add the test functions to the test_list[] array in quick_tests.h
- The order of the tests matters. The idea is to test each yaffs_function individualy and only using tested yaffs_components before using this new yaffs_function.
- This array consists of: {[test function], [the clean function], [name of the tests which will be printed when the test fails]},

The test file should now make and run(you may need to make clean first).
- PS: yaffs_fish() is a made up function for this README (in case you want to try and find this function in yaffs).

-BUGS AND WARNINGS
- bug with opening a file with a name of 1,000,000 char long with no errors.
- bug with unlinking a file with 1,000,000 get the error ENOENT but should be geting ENAMETOOLONG.
- bug with mounting a too long non-existant mount point. there are two errors here, ENOENT and ENAMETOOLONG.
- bug with mounting a non-existing mount point get the error ENODEV. should be getting ENOENT.
-
- WARNING- If yaffs is unmounted then most functions return ENODIR.
-
- FIXED-remove the printf which prints yaffs_mounting.
- FIXED-ENOSPC error in programs test_yaffs_open_ENOTDIR and test_yaffs_open_ENOENT.
- FIXED-ENOENT been returned by yaffs_read but the handle is good and the yaffs_open function does not return an error.
