./gradlew cAT failed in sample

You have no CI support, so I did a test run locally with ./gradlew cAT
But it fails with

> Task :android:connectedDebugAndroidTest
Starting 2 tests on API_30_Google_Api(AVD) - 11

The library has exactly the same limitations as the original and it seems like you hit this: facebook/screenshot-tests-for-android#224 (comment)

You have to do the same as the CI pipeline does:

screenshot-tests-for-android/.github/workflows/pull_request.yml

Lines 160 to 162 in 73f619f

	adb shell settings put global hidden_api_policy_p_apps 1
	adb shell settings put global hidden_api_policy_pre_p_apps 1
	adb shell settings put global hidden_api_policy 1

I hope this helps 🤞

I didn't see that it's a fork. Anyway, thank you !

Btw, this looks very promising https://github.com/android/testing-samples/tree/main/ui/espresso/ScreenshotSample.
It's super fast, but I've to figure out, where the images are stored to be able to grab it from device

Here they are ! It's so easy

Great! I'm happy this works for you as well 🎉

This is indeed a fork of https://github.com/facebook/screenshot-tests-for-android which I had to detach to be able to publish under my own credentials on mavencentral 🤷 The difference in features is this supports Gradle Configuration Cache (facebook/screenshot-tests-for-android#307)

if you're looking for some guidance, I recommend reading their documentation: https://facebook.github.io/screenshot-tests-for-android/#getting-started

However, if you're just considering to add screenshot testing, then I'd probably recommend using a different library: https://github.com/pedrovgs/Shot or even https://github.com/cashapp/paparazzi.
This, while being maintained, has a couple of design flaws that make it non-ideal for long term projects :)
