+Made by Timothy Manning <timothy@yaffs.net> on 04/11/2010
+
+
+
+
+How to add a test
+	First create the test .c and .h file.
+	The file name and test function name should be the same. 
+	This name should follow one of these formats: 
+	Test_yaffs_[function of yaffs which is been tested]
+	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
+		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]},	
+	
+	So add this line to the test_list[]: {test_yaffs_fish, test_yaffs_fish_clean, "test_yaffs_fish"},
+
+	Also include the test's .h file in the quick_test.h file: #include "test_yaffs_fish.h"
+
+	The test file should now make and run. 
+	
+	
+	
+
+
+
+	PS: yaffs_fish() is a made up function for this README (in case you want to try and find this function in yaffs). 
+
+
+BUGS
+	Needing to include int random_seed; and int simulate_power_failure = 0; in any main program using yaffsfs.h
+	ENOSPC error in programs test_yaffs_open_ENOTDIR and test_yaffs_open_ENOENT.
+	ENOENT been returned by yaffs_read but the handle is good and the yaffs_open function does not return an error.
