85 check to see if an error code is generated when there isn't an error.
89 First create the test .c and .h file.
90 The file name and test function name should be the same.
91 This name should follow one of these formats:
92 Test_yaffs_[function of yaffs which is been tested]
93 Test_yaffs_[function of yaffs which is been tested]_[error trying to be generated]
95 The .c file needs to contain two functions.
96 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.
97 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.
98 This second function needs to return -1 on a failure and 0 or greater on success.
100 The name of first function needs to be called the same as the file name (without the .c or .h)
101 The second function's name needs be the same as the first function but with "_clean" added on the end.
103 So if a test is been created for the yaffs function yaffs_fish() then create these files
105 Contains int test_yaffs_fish(void); int test_yaffs_fish_clean(void);
107 Which includes "lib.h", "yaffsfs.h" header files.
109 Next write the test code in these files then add these files to the Makefile.
111 Add the name of the test files' object file (test_yaffs_fish.o ) to the TESTFILES tag around line 50 of the Makefile.
115 Now add the test functions to the test_list[] array in quick_tests.h
116 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.
117 This array consists of: {[test function], [the clean function], [name of the tests which will be printed when the test fails]},
119 So add this line to the test_list[]: {test_yaffs_fish, test_yaffs_fish_clean, "test_yaffs_fish"},
121 Also include the test's .h file in the quick_test.h file: #include "test_yaffs_fish.h"
123 The test file should now make and run(you may need to make clean first).
127 PS: yaffs_fish() is a made up function for this README (in case you want to try and find this function in yaffs).
131 bug with opening a file with a name of 1,000,000 char long with no errors.
132 bug with unlinking a file with 1,000,000 get the error ENOENT but should be geting ENAMETOOLONG.
133 bug with mounting a too long non-existant mount point. there are two errors here, ENOENT and ENAMETOOLONG.
134 bug with mounting a non-existing mount point get the error ENODEV. should be getting ENOENT.
136 WARNING- If yaffs is unmounted then most functions return ENODIR.
138 FIXED-remove the printf which prints yaffs_mounting.
139 FIXED-ENOSPC error in programs test_yaffs_open_ENOTDIR and test_yaffs_open_ENOENT.
140 FIXED-ENOENT been returned by yaffs_read but the handle is good and the yaffs_open function does not return an error.
