WireMock VS json-schema-spec

This article reveals how to integrate WireMock into Fastify with ease, enabling developers to effortlessly generate mock responses for external services. Join us as we explore the straightforward process of seamlessly integrating and optimizing Fastify applications using WireMock for enhanced testing capabilities.

https://github.com/wiremock/wiremock is one such tool.

Me and my company use WireMock a lot, it's nice tool but didn't find any nice ways to integrate with PHPUnit. What is WireMock you may ask - it's tool for mocking http requests/responses, like 3-rd apis https://wiremock.org. Wanted to use our tool which was under private repository in other projects I work in, so decided to release our own in-house WireMock integration with PHPUnit as library so it can be used by other people - https://packagist.org/packages/cobiro/wiremock, features are pretty simple:

A nightmare indeed! Try wiremock

Yes I agree, mocking is a bit of an overloaded term, and the libraries we used for stubbing like gRPC Mock and WireMock also have `mock` in their name, even though they are real servers with stubbing

Yep and that comes from JSON Schema: https://json-schema.org/

I believe recent versions of OpenAPI are "compatible" with JSON Schema (at least they "wanted to be" last I checked as I was implementing some schema converters).

Even TypeScript is not enough to represent all of JSON Schema! But it gets close (perhaps if you remove validation rules and stuff like that it's a full match).

But even something like Java can represent most of it pretty well, specially since sealed interfaces were added. I know because I've done it :).

models.tf where I centralized all the Data model that API Gateway uses to perform input and output checks. Those use the JSON-schema specification. GitHub - psantus/serverless.api-gateway-dynamodb-integration.terraform

In the meantime, we are going to expand our backend with two endpoints: one for fetching data and another one for creating data. Fastify provides out-of-the-box support for API serialization and validation through its schema-based approach built on top of JSON Schema. Through the schema option, we can attach a schema definition to each route.

JSON-schema to define templates for request and response contents.

The syntax used to define the output is called JSON Schema. It is a standard way to define the structure of a JSON object. If you know zod, the spirit is similar. Based on Swarmion's roadmap, it will be possible to use zod schemas to defined contracts in the future, which will be super cool!

Essentially, all it does is attempt to generate the parameters to hypothetical or potential functions, which you using a JSON schema describe to ChatGPT.
