Infrastructure Testing

Validating IaC

Test infrastructure code before deploying to production.

Testing approaches:

Static analysis: terraform validate, tflint, checkov
Plan review: terraform plan output in PR comments
Integration tests: Terratest (Go), kitchen-terraform
Policy as code: OPA/Rego, Sentinel

Terratest example:

func TestVpc(t *testing.T) {
    opts := &terraform.Options{TerraformDir: "../modules/vpc"}
    defer terraform.Destroy(t, opts)
    terraform.InitAndApply(t, opts)
}

Interview tip: Mention infrastructure testing when discussing IaC. It signals operational maturity.
