How to test Jetpack Compose?

Question

I use the new Jetpack Compose, now comes time to test UI. Does anyone know the tools for testing it?
Since Espresso mainly relies on view I don't think that it can help.

For screenshot testing please see [this post](https://stackoverflow.com/a/69176420/8583692). — Mahozad, Sep 14 '21 at 16:25

Android has a code sample (Jetnews) that includes a couple of UI tests. This may help you to set up some tests or in the future, they may add additional code samples around UI testing.

Worth noting that currently there's no way to report on Code Coverage when doing Instrumented Tests with JetpackCompose's Components - so if a code coverage report is something you're interested on you might want to subscribe to [this GitHub issue](https://github.com/jacoco/jacoco/issues/1208) for updates. – Alves RC Aug 07 '22 at 14:00

In goo.gle/compose-testing you'll find the official documentation.

Most of the official code samples have UI tests. Apart from the common UI checks in JetNews, you can find animation+screenshot tests in Rally, Interop tests in Crane, screen recreation and navigation tests in Jetchat, etc.
