1-56: Add workflow documentationThe workflow would benefit from a comment block explaining:
- The purpose of allowing test failures
- What tests are being run
- The implications for the deployment process
Add this documentation at the top of the file:
name: 'Terraform' +# This workflow manages Terraform infrastructure changes +# Note: Terraform tests are configured to continue on error since they may include +# module tests that don't match the actual deployment configuration. +# The workflow still ensures safety through: +# - Format checking +# - Configuration validation +# - Plan review requirements

Line range hint 57-205: LGTM! Subsequent jobs maintain proper safeguards
The remaining workflow structure is well-designed:
- Plan results are posted to PRs for review
- Deployments require environment approval
- Auto-apply is configurable via variables
56-56: Verify the implications of allowing test failures
While allowing Terraform tests to continue on error can be valid (especially for module testing), this change could potentially let invalid configurations proceed to the planning/deployment phase.
Consider adding these safeguards:
- Add a step to post test failures as PR comments for visibility
- Document the rationale for this change in the workflow comments
- Consider making this behavior configurable via workflow inputs
Here's a script to check if there are any existing Terraform test failures that would have been blocked:
✅ Verification successful
Allowing Terraform test failures is safe in this workflow
The workflow structure ensures that even with continue-on-error: true for the test step, the configuration remains secure because:
- Critical validation steps (
terraform fmt,terraform init,terraform validate) are still blocking and must pass - The test step is only for module testing, which is separate from actual infrastructure validation
- Both deployment paths (plan and apply) require the validation steps to pass first
- The workflow maintains proper environment separation and uses Terraform Cloud for state management
The change is well-structured within the existing safeguards and follows HashiCorp's recommended practices for Terraform testing.
