What is it?

e2e is an end-to-end testing framework for web and mobile apps. Tests are written in TypeScript and can combine agent steps, where a goal is described in natural language and an agent operates the app to reach it, with conventional locators and assertions in the same test.

An agent step that a later assertion verifies records its actions, and subsequent runs replay those actions without model calls until the app changes. Tests without agent steps do not need a model. Model access can come from a subscription, an API key, or a local model.

The web engine runs on Chromium, Firefox, and WebKit through Playwright, and the mobile engine drives iOS simulators and Android emulators through agent-device. Running `npx e2e init` sets up a config and example test, and the repository includes example projects for Vite, Next.js, Astro, Expo, SwiftUI, Jetpack Compose, Kotlin Multiplatform, Flutter, and .NET MAUI.

  • 05Works with a subscription, an API key, or a local model.
  • 06Includes a GitHub reporter that posts results as a pull request comment.

Use cases

  • End-to-end testing of a web app's critical user flows such as checkout or billing upgrades.
  • Running the same test suite across web and iOS/Android apps.
  • Adding automated UI checks to pull requests in CI.
  • Writing tests in plain language when selector-based scripts are hard to maintain.

Quick start

  1. 1
