288 Add a truncate function for truncating a file size to -1.
290 What happens if a handle is opened to a file and the file is then deleted?
291 Check to see if yaffs generates an error code for no reason.
292 What happens when a file is opened with no modes set?
293 Add a test where a directory is moved. /fluffy/box. move "fluffy" to "/fluffy/frog".
294 What happens when yaffs is unmounted twice?
296 What happens when open a handle, unmount yaffs and then try to use the handle?
298 What happens when a mount point is mounted using mount2 with read only mode set and then a file is chmoded?
301 First create the test .c and .h file.
302 The file name and test function name should be the same.
303 This name should follow one of these formats:
304 Test_yaffs_[function of yaffs which is been tested]
305 Test_yaffs_[function of yaffs which is been tested]_[error trying to be generated]
307 The .c file needs to contain two functions.
308 The first function needs to contain the code for the main test and will
309 return -1 on a failure and 0 or greater on a success.
310 The second function needs contain the code for cleaning up after the test.
311 Cleaning up may include closing some open handles, recreating a file, ect.
312 This second function needs to return -1 on a failure and 0 or greater on success.
314 The name of first function needs to be called the same as the file
315 name (without the .c or .h)
316 The second function's name needs be the same as the first function but
317 with "_clean" added on the end.
319 So if a test is been created for the yaffs function yaffs_foo() then
322 Contains int test_yaffs_foo(void); int test_yaffs_foo_clean(void);
324 Which includes "lib.h", "yaffsfs.h" header files.
326 Next write the test code in these files then add these files to the Makefile.
328 Add the name of the test files' object file (test_yaffs_foo.o ) to the
329 TESTFILES tag around line 50 of the Makefile.
331 Now add the test functions to the test_list[] array in quick_tests.h
332 The order of the tests matters. The idea is to test each yaffs_function
333 individualy and only using tested yaffs_components before using this new
335 This array consists of:
336 {[test function], [the clean function], [name of the tests which will be printed when the test fails]},
338 So add this line to the test_list[]: {test_yaffs_foo, test_yaffs_foo_clean, "test_yaffs_foo"},
340 Also include the test's .h file in the quick_test.h file: #include "test_yaffs_foo.h"
342 The test file should now make and run(you may need to make clean first).
346 PS: yaffs_foo() is a made up function for this README (in case you want
347 to find this function in yaffs).
