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