What this fork adds

plexinc/Maestro tracks upstream Maestro and layers on the capabilities we need ahead of upstream:

• Apple TV (tvOS) support — a tvOS driver, device management (start-device --platform tvos), an RN Expo tvOS demo app, and tvOS e2e flows.
• Amazon Vega (Fire TV) support — a driver for Amazon's Vega OS (a Linux/React Native OS, not Android), driven through the vega/vda CLI: view hierarchy from the on-device automation toolkit, D-pad/touch/swipe/text input, and screenshots.
• Canvas-based UI (web) support — for D-pad-driven TV web apps (e.g. Lightning/WebGL): data-testid-first element selection, D-pad/arrow-key mapping (with Menu→back), URL-shaped appId detection, a focused: selector, and --platform web device selection.
• Bundled Maestro Studio, restored and TV-aware — re-adds the local maestro studio web IDE that upstream removed, plus a "TV mode" (auto-on for tvOS, toggleable for web) where taps/swipes and physical arrow keys / Enter / Esc drive the D-pad / select / back.
• major.minor.patch.build versioning — CLI_VERSION tracks upstream Maestro; a fork-owned PLEX_BUILD segment lets us ship fork-only builds without drifting from the inherited version.
• GitHub-direct distribution — install/uninstall scripts, CLI self-update, and releases all resolve straight from plexinc/Maestro releases (no external proxy).

Why Maestro?

Maestro is built on learnings from its predecessors (Appium, Espresso, UIAutomator, XCTest, Selenium, Playwright) and allows you to easily define and test your Flows.

By combining a human-readable YAML syntax with an interpreted execution engine, it lets you write, run, and scale cross-platform end-to-end tests for mobile and web with ease.

• Cross-platform coverage – test Android, iOS, and web apps (React Native, Flutter, hybrid) on emulators, simulators, or real devices.
• Human-readable YAML flows – express interactions as commands like launchApp, tapOn, and assertVisible.
• Resilience & smart waiting – built-in flakiness tolerance and automatic waiting handle dynamic UIs without manual sleep() calls.
• Fast iteration & simple install – flows are interpreted (no compilation) and installation is a single script.

Simple Example:

# flow_contacts_android.yaml

appId: com.android.contacts
---
- launchApp
- tapOn: "Create new contact"
- tapOn: "First Name"
- inputText: "John"
- tapOn: "Last Name"
- inputText: "Snow"
- tapOn: "Save"

Maestro Studio – Test IDE

Maestro Studio Desktop is a lightweight IDE that lets you design and execute tests visually — no terminal needed. It is also free, even though Studio is not an open-source project. So you won't find the Maestro Studio code here.

• Simple setup – just download the native app for macOS, Windows, or Linux.
• Visual flow builder & inspector – record interactions, inspect elements, and build flows visually.
