Show HN: Itdoc – Generate OpenAPI docs from your test code

Hey HN!

We built itdoc, generates OpenAPI documentation automatically from your integration tests (Jest or Mocha). No annotations, no manual syncing—just run your tests and get up-to-date API docs.

We were frustrated by outdated Swagger specs and repetitive documentation work. So we made a tool that turns your test cases into the single source of truth.

It outputs valid OpenAPI JSON and beautiful Redoc-style docs with zero extra effort.

In the Spring ecosystem, tools like `restdocs` already support this kind of workflow. But in the JavaScript/TypeScript world, there wasn’t a simple way to keep API docs in sync with real behavior—until now.

We're still in early stages and would love feedback from the community!
