Hi guys, is it possible to run UI tests from Fleet? I followed a few tutorials and docs but I always end up with this error:

Cannot invoke "String.toLowerCase(java.util.Locale)" because "android.os.Build.FINGERPRINT" is null
java.lang.NullPointerException: Cannot invoke "String.toLowerCase(java.util.Locale)" because "android.os.Build.FINGERPRINT" is null

AFAIK, Common UI testing can only test Compose UI not full intergration tests.
https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-test.html

If you want to test a UI flow navigating around interacting on a "device" then you still need to write tests in androidIntergrationTest src set.

It is also experimental so YMMV, and probably issues, create tickets on YouTrack the team is pretty responsive.

Maybe I'm wrong but I'm testing just a Composable like the example, this should be fine, right?

[Antonio Acuña Prieto]

import androidx.compose.ui.test.ExperimentalTestApi
import androidx.compose.ui.test.runComposeUiTest
import kotlin.test.Test
import androidx.compose.material.Text

class AppShould {
    @OptIn(ExperimentalTestApi::class)
    @Test
    fun `should show a test`() = runComposeUiTest {
        setContent {
            Text("1234")
        }
    }
}

This breaks with the error

Honestly without seeing the entire project setup, couldn't tell you....

this looks like a general issue https://kotlinlang.slack.com/archives/C3PQML5NU/p1714730508460919

is there a way to disable uiTests for android target and just use jvm?
