This document describes repeatable tests for the Terraform Best Practices MCP server.

Dependencies for Testing

Build the server:
```
npm run build
```
Reload VS Code so MCP config is reloaded:
- Cmd+Shift+P -> Developer: Reload Window

Use your configured server alias in Copilot Chat (for example @tf-best-practices; aliases are user-configurable).

Analyze Terraform code for modularity issues and suggest refactoring options.

Expected: Structured findings for module boundaries, naming consistency, and maintainability.

Generate a Terraform cost report and highlight optimization opportunities.

Expected: Cost-oriented summary with actionable optimization recommendations.

Suggest security hardening actions for Terraform code handling IAM, networking, and secrets.

Expected: Prioritized security recommendations and risk categories.

Generate a compliance summary from recent Terraform scan results.

Expected: Consolidated compliance output with pass/fail style categorization.

Suggest a Terraform architecture for multi-environment and multi-region deployment.

Expected: Architecture pattern recommendation with tradeoffs.

Analyze Terraform state management and suggest backend/locking improvements.

Expected: State safety findings around remote state, locking, and team workflows.

Run the test suite:

npm test

Run tests with coverage:

npm run test:coverage

npm run lint
npm run build

Ensure required CLI tools are installed and available in PATH
Re-run with optional tools removed from the request to validate core server behavior
