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

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 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
