A domain-specific language (DSL) expresses infrastructure resources through a higher-level configuration format, commonly YAML or JSON, rather than a general-purpose programming language. section 2.3.2
DSL-based infrastructure requires tooling that validates syntax, enforces formatting, and checks configuration values before deployment. Linting rules can also enforce security standards and run through Git hooks or continuous delivery workflows. section 2.3.2
Testing a Terraform DSL configuration
Store a network definition as Terraform-compatible JSON, then use pytest to parse the file and check the network name, subnet count, and IP address ranges. Generate a Terraform dry run when required values appear only after planning, and parse its JSON output without deploying resources. section 6.2.2
