+This directory provides Amulet tests that focus on verification of
+quantum-gateway deployments.
+
+If you use a web proxy server to access the web, you'll need to set the
+AMULET_HTTP_PROXY environment variable to the http URL of the proxy server.
+
+The following examples demonstrate different ways that tests can be executed.
+All examples are run from the charm's root directory.
+
+  * To run all tests (starting with 00-setup):
+
+      make test
+
+  * To run a specific test module (or modules):
+
+      juju test -v -p AMULET_HTTP_PROXY 15-basic-trusty-icehouse
+
+  * To run a specific test module (or modules), and keep the environment
+    deployed after a failure:
+
+      juju test --set-e -v -p AMULET_HTTP_PROXY 15-basic-trusty-icehouse
+
+  * To re-run a test module against an already deployed environment (one
+    that was deployed by a previous call to 'juju test --set-e'):
+
+      ./tests/15-basic-trusty-icehouse
+
+For debugging and test development purposes, all code should be idempotent.
+In other words, the code should have the ability to be re-run without changing
+the results beyond the initial run.  This enables editing and re-running of a
+test module against an already deployed environment, as described above.
+
+Manual debugging tips:
+
+  * Set the following env vars before using the OpenStack CLI as admin:
+      export OS_AUTH_URL=http://`juju-deployer -f keystone 2>&1 | tail -n 1`:5000/v2.0
+      export OS_TENANT_NAME=admin
+      export OS_USERNAME=admin
+      export OS_PASSWORD=openstack
+      export OS_REGION_NAME=RegionOne
+
+  * Set the following env vars before using the OpenStack CLI as demoUser:
+      export OS_AUTH_URL=http://`juju-deployer -f keystone 2>&1 | tail -n 1`:5000/v2.0
+      export OS_TENANT_NAME=demoTenant
+      export OS_USERNAME=demoUser
