+The Zaza tests for this charm require an OpenStack + StorPool cluster
+iSCSI connection setup. This setup is usually not available on developer
+machines. StorPool runs the Zaza tests on its [in-house Software
+Factory](https://spfactory.storpool.com).Zaza tests are [mapped to Zuul
+jobs](https://spfactory.storpool.com/r/plugins/gitiles/config/+/refs/heads/master/zuul.d/charm-cinder-storpool-iscsi.yaml).
+Each Zaza bundle has a separate job for better visibility.
