FileSystemTest

Are you building your own filesystem?
It is very difficult to test a filesystem.
Don't worry. FileSystemTest will help you.

Execution

FileSystemTest.exe [base_directory] [option] 
base_directory is mandatory it is the path where the tests will be runned
option list
#  -v [ --version ]          print the version number
#  -d [ --duration ]         print the api duration
#  -t [ --time ]             print the output with time as prefix of lines
#  -c [ --case ] arg         Run only the specified case.
#  -s [ --statistics ]       print api statistics
#  -f [ --full-log ]         print everything include utility functors.
#  -i [ --io-test ]          The program will run only for testing io performance.
#  -r [ --createfile-test ]  The program will run only for testing createfile.
#  -l [ --filelist-test ]    The program will run only for testing filelist.
#  -o [ --openfile-test ]    The program will run only for testing open files.
#  --starttime arg           The program will run on specified time.
#  --endtime arg             The program will run on specified time.
#  -q [ --quiet ]            print only test number and result in stdout (stderrstill have some detail) to compare results on 2 file system

Basic Example

# `C:\test_base_directory` is a filesystem base directory you want to test.
# It can be a NTFS volume, or Windows network(SMB) or your own filesystem.
# (You need to mount your filesystem first.)
# In this example, it points a `NTFS` volume(C:)
C:\YourPath> FileSystemTest.exe C:\test_base_directory -t -d -s -f

Result

The above command tries all APIs on the C:\test_base_directory (NTFS volume in this case) using all combinations of parameters and prints the results.
The result of the API can be either success or failure. (API fails doesn't mean the test failed)
You should also run this test on your own filesystem and compare it with NTFS's result using any diff tool you prefer.
If the result is different, your file system is not NTFS compliant and applications will not work properly.

If your file system is a network file system, it is better to compare it to the SMB(Windows Network Drive) rather than to NTFS.
