First, create a template that deploys only a single resource (like a SQL Server). When you are sure you have that resource correctly defined, add a resource that depends on it (like a SQL Database). When you have those two resources correctly defined, add other dependent resources (like auditing policies). In between each test deployment, delete the resource group to make sure you adequately testing the dependencies.
