Auto-generate load tests/synthetic test data from OpenAPI spec/HAR file
Hey HN, We just shipped a new AI-powered feature... BUT the "AI" piece is largely in the background. Instead of relying on a chatbot, we've integrated AI (with strict input & output guardrails) into a workflow to handle two specific tasks that would be difficult for traditional programming: 1. Identifying the most relevant base URL from HAR files, since it would be tedious to cover every edge case or scenario to omit analytics, tracking, and other network noise. 2. Generating synthetic data for API requests by passing the API context and faker-js functions to GPT-4. The steps are broken down…

In plain words
This tool automatically generates load tests and synthetic test data from OpenAPI specifications or HAR files. It uses AI to extract relevant base URLs from HAR files while filtering out analytics and tracking noise, then generates realistic synthetic data for API requests using GPT-4 with strict safeguards. Designed for developers who need to create API tests quickly, it focuses on reducing manual work and cognitive load through a guided workflow where users verify AI-generated outputs at each step.

Auto-generate an OpenAPI spec by listening to localhost2024 · github.com · ▲178Hey HN! We've developed OpenAPI AutoSpec, a tool for automatically generating OpenAPI specifications from localhost network traffic. It’s designed to simplify the creation of API documentation by just using your website or service, especially useful when you're pressed for time. Documenting endpoints one by one sucks. This project originated from us needing it at our past jobs when building 3rd-party integrations. It acts as a local server proxy that listens to your application’s HTTP traffic and automatically translates this into OpenAPI 3.0 specs, documenting endpoints, requests, and…
We built a tool that automatically generates API tests2022 · stepci.com · ▲108Hi, this is Mish and Sebastian. We are working on Step CI - a fully automated API testing platform for developers. Step CI works programming-language independent and for different API paradigms (REST, GraphQL, XML). Our CLI and test runner are available on GitHub (https://github.com/stepci) under the MPLv2 license. Since our last launch, Step CI is now able to generate automated tests for your API based on your OpenAPI (Swagger) spec. This saves you a lot of time as you never have to write and maintain your tests again! We would like to invite you to try our tool and give us…
