| /** |
| * These tests verify that a cloudant redundancy (master/slave) configuration |
| * works as expected. They will only run properly in an environment with two |
| * cloudant containers running concurrently and env var HOST_INDEX set to host0 in |
| * one container and host1 in the other. This test also assumes that redis and |
| * the active endpoint authorization are configured. For the auth set the |
| * ENDPOINT_AUTH env var in your containers to match the testing.auth property |
| * found in your whisk.properties. To configure redis simply set the REDIS_URL |
| * env var in your containers to point to the openwhisk redis container and make |
| * sure the container is deployed. You can run redis.yml to deploy it. |
