Test that an ElastiCache cluster node is available.

describe aws_elasticache_cluster_node(cache_cluster_id: "my-cluster-123", node_id: "0001") do
    its("status") { should eq 'available' }
end

Test that an Elasticache cluster engine is listening on port 11211.

describe aws_elasticache_cluster_node(cache_cluster_id: "my-cluster-123", node_id: "0001") do
    its("port") { should cmp 11211 }
end

Test that an Elasticache cluster node’s customer availability zone is us-east-2b.

describe aws_elasticache_cluster_node(cache_cluster_id: "my-cluster-123", node_id: "0001") do
    its("customer_availability_zone") { should cmp "us-east-2b" }
end
