# TestFlow

> TestFlow is the AI-native platform for electronics and semiconductor test automation. You connect your lab instruments, tell an AI agent what to test in plain English, and TestFlow generates the complete automation scripts and workflow in seconds, then runs them on your bench. It works with instruments from any vendor (Keysight, Tektronix, Keithley, Rohde & Schwarz, and more), with no vendor lock-in. There is a free version to start.

## About

TestFlow replaces unstructured, Excel-and-script-based lab validation with structured, repeatable, AI-generated test workflows. Instead of hand-writing SCPI commands or building tests in proprietary tools, a validation engineer connects their instruments, describes the test in plain English, and TestFlow produces the executable automation scripts and workflow, runs them in the lab, and returns analytics and audit-ready reports. The product is AI-native, built for this from the ground up rather than bolted on. Primary users are validation engineers, system application engineers, and hardware R&D leads at fabless semiconductor and electronics companies.

## Core capabilities

- Spec-to-test automation: upload a spec, get an executable validation plan and instrument scripts
- Universal instrument control across major lab hardware vendors
- Structured, reusable test flows instead of one-off scripts
- Automated analytics and report generation
- Team workflows with audit-ready execution
