e2e just passed 10,000 GitHub stars, and @kacperkapusciak is going live to show how to use it.
From npx e2e init to results on every pull request and run one test on web, iOS and Android. Then it's open Q&A.

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

e2e just crossed 500k weekly downloads on npm 🔥
check it out: github.com/tester-army/e2e
You can now run e2e tests inside @smolmachines microVMs.
Each test gets its own sandbox on your computer, with its own browser and its own database, ready in a couple of seconds.
Several agents can test separate copies of the same app at once without clicking through each other’s sessions, and every sandbox is wiped when its test ends.

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

Yesterday I had a livestream session covering intro to e2e.

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!

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

- @testmuai device provider package
- Performance & reliability improvements
try it now: ~/ npx e2e init
TesterArmy (YC P26) retweeted
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

Introducing /migrate-to-e2e
Allow your agent to migrate your existing end-to-end test suite to agentic e2e one slice at a time.
~/ npx skills add tester-army/e2e --skill migrate-to-e2e

Who's testing the code your agents write? @SzymonRybczak of @TesterArmy explains AI testing for web and mobile apps, including test plans built around each pull request.
