What if API testing worked like Terraform? (An experiment in Go)

Description and use

An experiment applying Terraform-like plan-first workflow to API testing: scenarios are written in TypeScript, compiled into a static plan, and executed in Go, improving test inspection and maintenance.

Problem

API test suites are hard to inspect, audit, and maintain due to ad-hoc code and lack of a declarative plan.

Outcome

Introduces a plan-first approach to API testing that improves test suite inspection, auditability, and maintainability.

Workflow

• Define API test scenarios in TypeScript.
• Run budment plan to generate and inspect a static execution plan without network calls.
• Compile the plan into a Go executable AST.
• Execute the compiled plan natively in Go to run the tests.
• Review and iterate on the plan as needed.

Evidence

I built a small project. You define workflows in TypeScript, run budment plan to inspect the execution hierarchy and hooks without making network requests, then execute the compiled AST natively in Go.
