+# Running database tests
+
+Running database tests locally require:
+
+* A systemd based Linux distro.
+* A recent version of [rkt](https://github.com/coreos/rkt) installed.
+
+The `standup.sh` script in the SQL directory is used to run databases in
+containers with systemd daemonizing the process.
+
+```
+$ sudo ./storage/sql/standup.sh create postgres
+Starting postgres. To view progress run
+
+  journalctl -fu dex-postgres
+
+Running as unit dex-postgres.service.
+To run tests export the following environment variables:
+
+  export DEX_POSTGRES_DATABASE=postgres; export DEX_POSTGRES_USER=postgres; export DEX_POSTGRES_PASSWORD=postgres; export DEX_POSTGRES_HOST=172.16.28.3:5432
+
+```
+
+Exporting the variables will cause the database tests to be run, rather than
+skipped.
+
+```
+$ # sqlite takes forever to compile, be sure to install test dependencies
+$ go test -v -i ./storage/sql
+$ go test -v ./storage/sql
+```
+
+When you're done, tear down the unit using the `standup.sh` script.
+
+```
+$ sudo ./storage/sql/standup.sh destroy postgres
+```
