Quadrastack – CLI tool for mocking and testing APIs with YAML playbooks

Summary: Quadrastack is a command-line interface for defining, running, and automating API tests using readable YAML playbooks. It integrates mocking, load testing, and CI workflows while enabling collaboration between developers and QA through a single test format.

What it does

Quadrastack lets users write API tests in YAML that include requests, assertions, and scenarios. It provides a built-in mock server, load testing with concurrency control, and a VS Code extension to run tests directly from the editor.

Who it's for

It is designed for development and QA teams needing a unified, readable test format that works across CI pipelines and local environments without cloud dependencies.

Why it matters

It addresses fragmented API testing workflows by consolidating tests into a single, readable format that both developers and QA can maintain and execute consistently.
