Regarding testing with the `AndroidComposeTestRule`: What is the reason that I cannot declare

<activity android:name="androidx.activity.ComponentActivity" />

in the

androidTest/AndroidManifest.xml

but have to do it in

main/AndroidManifest.xml

? 🤔

That's not related to Jetpack Compose at all. Also seems like an XY problem (http://xyproblem.info/), I don't understand why you want to do that.

Because this Activity is only used for testing and needed by the AndroidComposeTestRule. And it does work for a regular ActivityRule, that is why I thought it might be a compose problem

@flosch Well, I don't know about this, but the JetNews sample definitely has UI tests, and I can confirm they run: https://github.com/android/compose-samples/tree/cd65f2520db270c95abe3672df751e90a2a8709e/JetNews/app/src You might want to check it out from Android Studio (File > New > Import Sample > type "Jetnews") https://github.com/android/compose-samples/tree/cd65f2520db270c95abe3672df751e90a2a8709e/JetNews/app/src

Yes, thanks, I was looking at that example. I already created my own project and ui tests which all works great, however I think the

Activity

declaration for testing should not be in the production

AndroidManifest

but in the

androidTest

`AndroidManifest`🤷‍♂️

Might make sense to open an issue then
