Quality Assurance Agent: Reimagining Software Quality with AI-Driven Autonomous Testing
LinkedIn built an autonomous QA Agent using AI and vision-language models to test its apps across the huge range of UI permutations that manual and scripted testing can't keep up with. It runs a multi-model setup (planning, error detection, and a fine-tuned model that converts instructions into screen coordinates) and a hybrid “System 1/System 2” architecture: fast deterministic replay when the UI is unchanged, and slower agentic reasoning when it shifts.
