07/13/2023, 8:28 AMIn an Android project, is it possible to run Compose UI tests without a device (or emulator), on just the JVM? Sounds like it should be possible but I can’t find information on that.

07/13/2023, 10:24 AMPaparazzi looks good, but since official screenshot testing from Google should be coming soon, I’d rather wait for that.

07/13/2023, 10:25 AMIf I was more interested here in tests that interact with the component, not screenshot tests, it looks like Robolectric is the only way? I would have imaged that since Android Studio can run Compose previews, and Compose can also run on the Desktop target, tests should be able to run without a device too.

07/13/2023, 3:06 PM@Marcin Wisniowski we are working on just that, host side screenshot testing without need for a device. It’s not ready yet though.

09/28/2023, 2:33 PM@Chris Sinco [G] Is there anywhere I can “star”/follow progress/get notified about Compose screenshot testing when it’s released?

09/28/2023, 7:38 PMWe don’t have a public issue tracking this unfortunately. We hope to release something in canary in Q1 2024 but no promises. We do plan to discuss more of the details though at droidCon London at the end of October.
