Maestro is a declarative mobile and web UI automation framework designed for end-to-end testing. It operates by querying the native accessibility tree of an application, allowing for black-box testing without requiring source code instrumentation or platform-specific dependencies.
The framework distinguishes itself through a unified command syntax that abstracts interactions across Android, iOS, and web environments. It features a dynamic synchronization engine that automatically pauses test execution to account for non-deterministic animations and network-dependent content loading, ensuring stability without manual delays. Additionally, it provides system-level device orchestration, enabling the simulation of real-world conditions such as permission handling, geolocation, and media storage manipulation.
Maestro supports complex test scenarios through modular, reusable flows and an integrated scripting engine that allows for conditional logic, branching, and dynamic data generation. It includes built-in capabilities for visual regression testing, AI-driven verification, and seamless integration into continuous integration and deployment pipelines.
The project is configured via human-readable configuration files and provides a command-line interface for managing test execution, environment settings, and reporting across distributed infrastructure.
