Made by Timothy Manning on 04/11/2010 This test is designed to test the response and error handling of the yaffs functions. compile command: make run command: ./quick_tests command line options: -h prints the available command line options. -c tests will continue even if a test fails, rather than exiting the test. -v verbose mode. will print all messages. -q quiet mode. will not print any messages. -t [number] sets the yaffs_trace() function to the number. -n [number] sets the number of randomly selected tests to run after the test has run through after running all of listed tests.

test_yaffs_access_ENOENT_generated_with_a_dangling_symbloic_link Add a truncate function for truncating a file size to -1. What happens if a handle is opened to a file and the file is then deleted? Check to see if yaffs generates an error code for no reason. What happens when a file is opened with no modes set? What happens when yaffs is unmounted twice? What happens when open a handle, unmount yaffs and then try to use the handle? What happens when a mount point is mounted using mount2 with read only mode set and then a file is chmoded? Try to remove lost and found dir and replace it with a file of the same name. Change the mode of the lost and found dir to read only.

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_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_foo.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_foo, test_yaffs_foo_clean, "test_yaffs_foo"}, Also include the test's .h file in the quick_test.h file: #include "test_yaffs_foo.h" The test file should now make and run(you may need to make clean first). PS: yaffs_foo() is a made up function for this README (in case you want to find this function in yaffs).
