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