+#### Testing with a rpms/ruby pull-request
+
+Run a scratch build x86_64 on the branch used for the rpms/ruby pull-request
+that you want to test:
+
+```
+$ fedpkg --release rawhide scratch-build --srpm --arches x86_64
+```
+
+Run the following command with the above build's x86_64 task ID (not build ID)
+to download the RPM packages. Remove the SRPM file to keep only binary RPM files
+in the `/path/to/packages` directory to avoid an error on the later `tmt`
+command.
+
+```
+$ pwd
+/path/to/packages
+$ koji download-task TASK_ID
+$ rm *.src.rpm
+```
+
+Run the following command to run the tests with the above RPM files.
+
+```
+$ tmt -c distro=fedora-rawhide run --all \
+  prepare --insert --how install -D /path/to/packages \
+  provision -h virtual -i fedora-rawhide
