Architecture
The main distinctions between IaC testing tools arise from their ability to perform impact analysis against the runtime environment, considering potential resource drift, and to evaluate impacts beyond the unit level. Focusing solely on unit-level testing may lead to overlooking critical issues or generating false-positive alerts.

Coverage
When evaluating IaC testing tools, support for multiple languages may seem like a desirable feature; however, it is less important than the tool's overall quality. A high-quality tool should prioritize accurate and comprehensive tests for a specific language, ensuring better issue detection and reducing false positives. In essence, it's better to have an effective testing tool for one language than a mediocre one for multiple languages.
