+### Testing
+
+You can run the tests in your local environment.
+
+Install [`tmt`](https://tmt.readthedocs.io/en/stable/overview.html#install).
+
+```
+$ sudo dnf install tmt+all
+```
+
+Run the following command to run the tests for Fedora rawhide:
+
+```
+$ tmt -c distro=fedora-rawhide run --all provision -h virtual -i fedora-rawhide plans --default
+/var/tmp/tmt/run-NNN
+...
+```
+
+The tmt's provisioning method virtual (`tmt run provision -h virtual`) must be used, otherwise the tests fail due to known issues with container provisioning method (`tmt run provision -h container`). Also note the `run-NNN` printed on the output of the command. This represents the run ID used with `tmt run --id` option in later steps.
+
+Run the following command to see the report, setting the value of the above run ID to the `--id` option. As this repository doesn't have tmt's plans to run the tests, we need to set the `plans --default` to use the default plans. See [this tmt's document](https://tmt.readthedocs.io/en/stable/stories/cli.html#report) about the `tmt run report` options.
+
+```
+$ tmt run --id run-NNN report -vvv plans --default
+```
