Linux kernel block layer testing framework

blktests

blktests is a test framework for the Linux kernel block layer and storage stack. It is inspired by the xfstests filesystem testing framework.

Getting Started

The dependencies are minimal, but make sure you have them installed:

• bash 4
• GNU coreutils
• GNU awk
• util-linux
• fio

Add the list of block devices you want to test on in a file named config:

TEST_DEVS=(/dev/nvme0n1 /dev/sdb)

And as root, run the default set of tests with ./check.

Note that these tests are destructive, so don't add anything to the TEST_DEVS array containing data that you want to keep.

See here for more detailed information on configuration and running tests.

Adding Tests

The ./new script creates a new test from a template. The generated template contains more detailed documentation.

Pull requests on GitHub and patches to [e-mail] are both accepted. See here for more information on contributing.
