details below:
some of the test case just chose random 10 and do it
1. Initialize disk
1) delete simulated disk file "[login to view URL]"
2) run program "sfstest"
3) type command "i" -> "1"
2. Create file
1) (positive case)type command "m" -> "0" -> "/file1" -> success
2) (positive case)type command "m" -> "0" -> "/file2" -> success
3) (negative case)type command "m" -> "0" -> "/aaabbbccc" -> exceed maximal characters
4) (negative case)type command "m" -> "0" -> "aaa" -> error -> invalid path
3. Open file
1) (positive case)type command "o" -> "/file1" -> get file descriptor "0"
2) (positive case)type command "o" -> "/file2" -> get file descriptor "1"
3) (negative case)type command "o" -> "/abc" -> file not exist
4. Read/Write file
1) (positive case)type command "w" -> file descriptor "0" -> start location "-1" -> length "5" -> "12345" -> success
2) (positive case)type comamnd "r" -> file descriptor "0" -> start location "0" -> length "5" -> show "12345"
3) (positive case)type command "w" -> file descriptor "0" -> start location "2" -> length "2" -> "aa" -> success
4) (positive case)type comamnd "r" -> file descriptor "0" -> start location "0" -> length "5" -> show "12aa5"
5) (negative case)type command "w" -> file descriptor "0" -> start location "10" -> length "2" -> "aa" -> file is not long enough
5. Close file
1) (positive case)type command "c" -> get file descriptor "0" -> success
2) (negative case)type command "c" -> get file descriptor "5" -> invalid file descriptor
6. Delete file
1) (positive case)type command "d" -> "file1"-> success
2) (negative case)type command "d" -> "file2" -> file is in use
1. Create hierarchy directories and files as following structure
/
|---/dir1
|---/sub1
|---file1
|---file2
|---/dir2
|---file3
1) Create directory "/dir1"
2) Create directory "/dir2"
3) Create directory "/dir1/sub1"
4) Create regular file "/dir1/sub1/file1"
5) Create regular file "/dir1/file2"
6) Create regular file "/file3"
7) (negative case) type command "m" -> "/dir3/sub2" -> 1 -> give error msg
8) (negative case) type command "m" -> "/dir3/file4" -> 0 -> give error msg
2. Open directories and files
1) Open root directory: "o" -> "/" -> get file descriptor "0"
2) Open directory: "o" -> "/dir1" -> get file descriptor "1"
3) Open sub directory: "o" -> "/dir1/sub1" -> get file descriptor "2"
4) Open regular file: "o" -> "/dir1/sub1/file1" -> get file descriptor "3"
5) (negative case): "o" -> "/dir3" -> not exist
3. Read directory
1) Read root directory: "R" -> "0" -> display the first entry "dir1" -> "R" -> "0" -> display the second entry "dir2" -> "R" -> "0" -> display the third entry "file3"
2) Read directory "/dir1": "R" -> "1" -> display the first entry "sub1" -> "R" -> "1" -> display the second entry "file2" -> "R" -> "1" -> display no more entry
4. File type
1) Type of root directory: "t" -> "/" -> DIRECTORY
2) Type of regular file: "t" -> "/dir1/sub1/file1" -> REGULAR
3) (negative case): "t" -> "/dir1/file4" -> not exist
5 File size
1) Size of root directory: "s" -> "/" -> should be 3 in this case
2) Size of "/dir1": "s" -> "/dir1" -> should be 2 in this case
3) Size of regular file: "w" -> "3" -> "-1" -> "5" -> "12345" -> "w" -> "3" -> "-1" -> "2" -> "ab" -> "s" -> "/dir1/sub1/file1" -> should be 7
4) Repeat test 3) through overwriting some chars
5) (negative case) give a file not exist
6. Close and delete directory
1) (negative case): "d" -> "/dir1" -> give error of directory/file in use
2) (negative case): close all directory and files -> "d" -> "/dir1" -> give error of directory not empty
3) (positive case): "c" -> "3" -> "d" -> "/dir1/sub1/file1" -> "c" -> 2 -> "d" -> "/dir1/sub1" -> "d" -> "/dir1/file2" -> "c" -> "1" -> "d" -> "/dir1"
7. No data lost after restarting
1) create some files/directories; kill the file system program and restart it; files/directories still exist
8. All test cases listed in part 2 are also required in final evaluation.
