How do I validate multiple resources at once?

The skill can help you write complex 'assert' blocks using HCL functions like 'alltrue' and 'for' loops to validate configurations across entire resource collections.

What versions of Terraform does this skill support?

This skill focuses on the native testing framework introduced in Terraform 1.6.0, including advanced mocking features from 1.7.0 and parallel execution from 1.9.0.

Can I test Terraform modules without creating real cloud resources?

Yes, this skill provides guidance on using 'plan' mode within run blocks and implementing mock providers to validate logic without provisioning actual infrastructure.

Where should I store my Terraform test files?

Terraform looks for test files with the .tftest.hcl or .tftest.json extension, typically organized within a 'tests/' directory at the root of your module.

安全与测试

Validates infrastructure-as-code configurations using the native Terraform testing framework and .tftest.hcl patterns.

This skill equips Claude with the specialized knowledge required to implement robust testing suites for Terraform modules. It provides deep guidance on writing and executing .tftest.hcl files, covering both unit tests (plan-based) and integration tests (apply-based). By leveraging core concepts like run blocks, assertion logic, and provider mocking introduced in Terraform 1.7.0+, this skill helps developers ensure infrastructure stability, validate complex logic without creating real resources, and troubleshoot execution syntax. It is an essential companion for module authors who need to maintain high-quality, regression-free infrastructure configurations.
