# Testing / `smart` SMART File System

This is a test of the SMART file system that derives from `testing/nxffs`.

- `CONFIG_TESTING_SMART` – Enable the SMART file system example.
- `CONFIG_TESTING_SMART_ARCHINIT` – The default is to use the RAM MTD device at
  `drivers/mtd/rammtd.c`. But an architecture-specific MTD driver can be used
  instead by defining `CONFIG_TESTING_SMART_ARCHINIT`. In this case, the
  initialization logic will call `smart_archinitialize()` to obtain the MTD
  driver instance.
- `CONFIG_TESTING_SMART_NEBLOCKS` – When `CONFIG_TESTING_SMART_ARCHINIT` is not
  defined, this test will use the RAM MTD device at `drivers/mtd/rammtd.c` to
  simulate FLASH. In this case, this value must be provided to give the number
  of erase blocks in MTD RAM device. The size of the allocated RAM drive will
  be: `CONFIG_RAMMTD_ERASESIZE * CONFIG_TESTING_SMART_NEBLOCKS`.
- `CONFIG_TESTING_SMART_MAXNAME` – Determines the maximum size of names used in
  the filesystem.
- `CONFIG_TESTING_SMART_MAXFILE` – Determines the maximum size of a file.
- `CONFIG_TESTING_SMART_MAXIO` –  Max I/O, default `347`.
- `CONFIG_TESTING_SMART_MAXOPEN` – Max open files.
- `CONFIG_TESTING_SMART_MOUNTPT` – SMART mountpoint.
- `CONFIG_TESTING_SMART_NLOOPS` – Number of test loops. default `100`.
- `CONFIG_TESTING_SMART_VERBOSE` – Verbose output.
