| # Block device testing |
| |
| __WARNING: All of the following tests are destructive, and they may not |
| ask for confirmation before executing. Run at your own risk.__ |
| |
| ## Protocol testing |
| |
| *blktest* is an integration which may be used to check adherence to the block protocol. |
| |
| ```shell |
| $ blktest -d /dev/class/block/000 |
| ``` |
| |
| ## Filesystem testing |
| |
| *fs-test* is a filesystem integration test suite that can be used to verify |
| Fuchsia filesystem correctness on a filesystem. |
| |
| To avoid racing with the auto-mounter, it is recommended to run this |
| test with the kernel command line option "zircon.system.disable-automount=true". |
| |
| TODO(ZX-1604): Ensure this filesystem test suite can execute on large |
| partitions. It is currently recommended to use this test on a 1-2 GB GPT |
| partition on the block device. |
| |
| ```shell |
| $ /boot/test/fs/fs-test -d /dev/class/block/000 -f minfs |
| ``` |
| |
| ## Correctness testing |
| |
| *iochk* is a tool which pseudorandomly reads and writes to a block device to check for errors. |
| |
| ```shell |
| $ iochk -bs 32k -t 8 /dev/class/block/000 |
| ``` |
| |
| ## Performance testing |
| |
| *iotime* is a benchmarking tool which tests the read and write performance of block devices. |
| |
| ```shell |
| $ iotime read fifo /dev/class/block/000 64m 4k |
| ``` |
| |
