Testing

Unit tests

rasdaemon provides cmocka groups for core data structures, trace-event handlers, optional feature modules, vendor decoders, and database backends. Event-handler tests use scripted trace records, so they do not require a kernel tracefs instance or injected hardware errors.

Install libcmocka-devel or libcmocka-dev to enable the tests. Build and run the hermetic suite with:

$ make
$ meson test -C build --print-errorlogs

List the groups present in the selected Meson configuration or run one group directly with:

$ ./build/unittest --list-groups
$ ./build/unittest --group events

SQLite is included in the hermetic Meson suite. Its group can also be run directly:

$ ./build/unittest --group sqlite3

The MySQL/MariaDB and PostgreSQL groups use real database servers and must be run explicitly after provisioning their test databases:

$ ./build/unittest --group mysql
$ ./build/unittest --group postgresql

Error injection

contrib/edac-fake-inject injects EDAC errors when the kernel was built with CONFIG_EDAC_DEBUG and an EDAC driver is running. Run it as root while rasdaemon is active:

# contrib/edac-fake-inject

External injection tools are available for other error sources:

• MCE: https://git.kernel.org/pub/scm/utils/cpu/mce/mce-inject.git

• APEI: https://git.kernel.org/pub/scm/linux/kernel/git/gong.chen/mce-test.git/

• AER: https://git.kernel.org/pub/scm/linux/kernel/git/gong.chen/aer-inject.git/
