Regarding testing with the `AndroidComposeTestRule`: What is the reason that I cannot declare `&lt;activity android:name="androidx.activity.ComponentActivity" /&gt;` in the `androidTest/AndroidManifest.xml` but have to do it in `main/AndroidManifest.xml` ? :thinking_face:

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

<@U011E3QASP8> 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 &gt; New &gt; Import Sample &gt; type "Jetnews")

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`:man-shrugging:
