A comprehensive guide to testing infrastructure as code with Pulumi, covering all three testing layers: unit tests using mocked cloud providers (no credentials needed, runs in milliseconds), integration tests that deploy real resources via the Automation API, and policy-as-code checks that enforce compliance rules on every preview and deploy. Complete runnable examples are provided in Python, TypeScript, Go, C#, and Java. The guide also compares Pulumi's testing approach to Terraform (Terratest and terraform test), highlighting language cohesion as a key advantage — infrastructure, tests, and policies all written in the same general-purpose language using familiar test frameworks like pytest, Mocha, and go test.
