Autonomous AI Testing Tool

DRCODE's main product — agents that test APIs and UIs on their own. I built the UI-testing toolkit from scratch and fixed/improved the API E2E side.

Overview

Two halves: an API E2E tester (a Chrome extension captures real calls, the server generates input variants and test cases), and a UI-testing toolkit I built from the ground up — Playwright driven as an MCP by an agent that mimics a tester's clicks, then tries to break the flow, saving each attempt as a script.

On the API side I fixed bugs in the E2E flow and improved test-case generation. Tests ran only against staging/dev with dedicated credentials.
