TesterArmy

TesterArmy provides an open source AI testing framework that caches agent actions to replay them without model calls.

TesterArmy is a customizable TypeScript testing framework for web and mobile applications that combines deterministic assertions with agentic steps. The framework remembers agent actions and replays them when possible to reduce repeated reasoning and lower token costs. Users can choose their preferred AI model, connect through a gateway, and define testing goals in plain language. It supports web testing, iOS simulators, and Android emulators through a shared API and custom execution backends. Migration guides are available for Playwright, Cypress, Selenium, Detox, and Maestro.
