What if writing an @e2e test started with simply using your app? 🧪 Meet Testing Studio in Mobile Dev Record a flow → view & edit the steps → run it. All inside your ADE. Don't want to record? An agent can capture the flow for you. See the 🧵

Coding agents write mobile code faster than any team can review it. 🙌 Introducing Expo Simulators: cloud simulators built for agents. Your agent runs its change on a cloud simulator or emulator and brings back the recording before it asks for your attention.

Often the best way to optimize something is to do less With e2e filters you can drastically cut your end-to-end CI times by only running tests relevant to your change

e2e x agent-desktop 🧪 Weekend experiment: e2e tests for native desktop apps. the new engine protocol in e2e lets an engine run in its own process, in any language. Here's a demo of a small Rust engine on top of agent-desktop. github.com/tester-army/e2e

Introducing agent-desktop agent-browser, for your whole computer → Computer Use for any coding agent → macOS, Windows and Linux → Runs in bg while you keep working → Agents use your computer in parallel, each with its own cursor

The best way to speed up your CI is to run only the tests that matter. I wrote a blog post on how to do it with e2e and the Filters API
How to make your CI 10x faster with e2e?

You can now iterate faster while writing e2e tests Agents (and humans!) can use `--watch` to rerun only the e2e tests that changed ~/ npx e2e run --watch

Going live tomorrow to show how I use e2e day to day We'll go through the setup, replaying verified agent steps without the model, and running it on GitHub Actions CI Then open Q&A, so bring your questions! 📅 Thu, Oct 22 · 9 AM PT / 6 PM CEST tester.army/e2e/sessions/int…

Payments are notoriously difficult to end-to-end test iframes inside of iframes, iframe for every field… hell on earth for developers but not for agents! define e2e tests in plain english and agents take care of the rest ~/ npx e2e init

One of the most powerful features of agentic e2e are *personas* Your agent larps as an architect in Lyon who only speaks French or pharmacist in Cairo who only reads Arabic Great for catching missing i18n or broken RTL and you still write tests in English

In e2e, you can use one model to run `agent.act`s, and a different one to answer `agent.assert`ions That way you can use faster model for navigating your app and smarter model for checking if the app actually works according to your spec
