I believed this too. Then I opened my app on a Pixel 9 Pro Fold and was surprised that the "foldable" layout was skipped, and the "tablet" layout appeared on the screen.

“We don’t have time for visual testing.” That’s what many Android developers say.
Many developers think that creating visual tests is hard, as they require separate test cases, learning new frameworks and approaches, and dealing with flaky CI pipelines.

I’ll be speaking at @droidcon.it in Turin about Android UI testing.
Here’s what I’ll cover:
• Getting started with natural language UI tests
• A technical comparison between Journeys, Espresso, UiAutomator, and Compose UI Test
Spoiler: There’s no one-size-fits-all solution.

Android Studio Narwhal now includes a "Generate Preview" with Gemini.
My thoughts after playing with it:
• It generates fake data for previews
• It struggles with custom types
• It needs modification, but it speeds up the process
In the future, it might be a helpful tool for adding visual tests.
