Setting requestedOrientation results in crash

[Saral]

I am observing crash with the below AndroidTest code. Could someone please help me in fixing this?

package com.example.sandbox
import android.content.pm.ActivityInfo
import androidx.compose.ui.test.ComposeTimeoutException
import androidx.compose.ui.test.junit4.createAndroidComposeRule
import androidx.test.core.app.ActivityScenario
import org.junit.Rule
import org.junit.Test

class MainActivityTest {
    @get:Rule
    val rule = createAndroidComposeRule<MainActivity>()
    private lateinit var scenario: ActivityScenario<MainActivity>

    @Test
    fun sandboxTest() {
        scenario = ActivityScenario.launch(MainActivity::class.java)
        rule.waitForIdle()
        rule.activity.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
    }
}

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContent {
            SandBoxTheme {
                Scaffold(modifier = Modifier.fillMaxSize()) { innerPadding ->
                    Greeting(
                        name = "Android",
                        modifier = Modifier.padding(innerPadding)
                    )
                }
            }
        }
    }
}

@Composable
fun Greeting(name: String, modifier: Modifier = Modifier) {
    Text(
        text = "Hello $name!",
        fontSize = 40.sp,
        modifier = modifier
            .padding(50.dp)
    )
}

Got it resolved with this suggestion:

Setting requestedOrientation results in crash

I am trying to test an Android app built with Kotlin and Jetpack compose for configuration changes like switching to LANDSCAPE/PORTRAIT mode. When I set the orientation to Landscape/Portrait, I see...

Stack overflow is a pretty good place for development/coding questions. The community seems really nice for the most part.
