The pstore_tests script includes test cases which check pstore's
behavior before crash (and reboot).
The test cases are currently following.
- Check pstore backend is registered
- Check pstore console is registered
- Check /dev/pmsg0 exists
- Write unique string to /dev/pmsg0
The unique string written to /dev/pmsg includes UUID. The UUID is also
left in 'uuid' file in order to enable us to check if the pmsg keeps the
string correctly after reboot.
Example usage is following.
# cd /path/to/selftests
# make run_tests -C pstore (or just .pstore/pstore_tests)
make: Entering directory '/path/to/selftests/pstore'
=== Pstore unit tests (pstore_tests) ===
UUID=b49b02cf-b0c2-4309-be43-b08c3971e37f
Checking pstore backend is registered ... ok
backend=ramoops
cmdline=console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait mem=768M ramoops.mem_address=0x30000000 ramoops.mem_size=0x10000
Checking pstore console is registered ... ok
Checking /dev/pmsg0 exists ... ok
Writing unique string to /dev/pmsg0 ... ok
selftests: pstore_tests [PASS]
make: Leaving directory '/path/to/selftests/pstore'
We can also see test logs later.

To test pstore in earnest, we have to cause kernel crash and check
pstore filesystem after reboot.
We add two scripts:
- pstore_crash_test
This script causes kernel crash and reboot. It is executed by
'make run_pstore_crash' in selftests. It can also be used with kdump.
- pstore_post_reboot_tests
This script includes test cases which check pstore's behavior after
crash and reboot. It is executed together with pstore_tests by
'make run_tests [-C pstore]' in selftests.
The test cases in pstore_post_reboot_tests are currently following.
- Check pstore backend is registered
- Mount pstore filesystem
- Check dmesg/console/pmsg files exist in pstore filesystem
- Check dmesg/console files contain oops end marker
- Check pmsg file properly keeps the content written before crash
- Remove all files in pstore filesystem
Example usage is following.
