# Testing / `fstest` Generic File System Test

This is a generic file system test that derives from `testing/nxffs`. It was
created to test the tmpfs file system, but should work with any file system
provided that all initialization has already been performed prior to starting
the test.

This test a a general test for any file system, but includes some specific hooks
for the SPIFFS file system.

- `CONFIG_TESTING_FSTEST` – Enable the file system example.
- `CONFIG_TESTING_FSTEST_MAXNAME` – Determines the maximum size of names used in
  the filesystem.
- `CONFIG_TESTING_FSTEST_MAXFILE` – Determines the maximum size of a file.
- `CONFIG_TESTING_FSTEST_MAXIO` – Max I/O, default `347`.
- `CONFIG_TESTING_FSTEST_MAXOPEN` – Max open files.
- `CONFIG_TESTING_FSTEST_MOUNTPT` – Path where the file system is mounted.
- `CONFIG_TESTING_FSTEST_NLOOPS` – Number of test loops. default `100`.
- `CONFIG_TESTING_FSTEST_VERBOSE` – Verbose output.

EXAMPLE
  fstest -m /mnt -n 10 – Test /mnt 10 times
  fstest -h            – Get help message
  fstest               – Test path define by `CONFIG_TESTING_FSTEST_MOUNTPT`
                         `CONFIG_TESTING_FSTEST_NLOOPS` times
