Testing
OpenTofu is the open-source, community-driven fork of Terraform, created after HashiCorp changed Terraform's license from MPL to BSL 1.1 in August 2023. If you've been using Terraform — and especially if you've built tests with Terratest or the native .tftest.hcl framework

Writing Ansible roles without tests is a recipe for broken playbooks. Molecule is the official testing framework for Ansible roles and collections. It lets you spin up containers, run your role against them, verify the results, and tear everything down — all with a single command. This guide covers Molecule with
Testing
Most Ansible roles are never tested. You write the role, run it on a server, see that it "works," and commit. The next engineer who touches it runs into a failure on Ubuntu 22 that worked on Ubuntu 20, or discovers the role isn't idempotent — running
Testing
Service meshes like Istio and Linkerd add a powerful layer of infrastructure between your microservices: traffic management, mTLS encryption, observability, and resilience features. But they also add complexity to testing. A service that works fine in unit tests may behave unexpectedly when running behind a mesh proxy. This guide covers
Testing
Most teams treat test environment provisioning as an operations problem: file a ticket, wait for an engineer to spin something up, hope it matches what you actually need. Infrastructure as Code flips this. When your test environments are defined in Terraform, any team member can provision a complete, correctly configured
Testing
Infrastructure code breaks. An S3 bucket gets configured with public ACLs. A security group rule opens port 22 to the world. A load balancer misconfiguration sends traffic to the wrong target group. These aren't hypothetical — they are the kinds of bugs that make it to production because the
