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