Robolectric tests are supposedly supported now by Jetpack Compose, since beta09. But I attempted to implement a very simple test (the test for the feature in AOSP, see runClickScenario()) but it does not work for me. Error I get is:
java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.lang.IllegalAccessException: class androidx.test.espresso.base.ThreadPoolExecutorExtractor$2 cannot access a member of class androidx.loader.content.ModernAsyncTask with modifiers "public static final" java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.lang.IllegalAccessException: class androidx.test.espresso.base.ThreadPoolExecutorExtractor$2 cannot access a member of class androidx.loader.content.ModernAsyncTask with modifiers "public static final" at androidx.test.espresso.Espresso.onIdle(Espresso.java:15) at androidx.test.espresso.Espresso.onIdle(Espresso.java:1) at androidx.compose.ui.test.junit4.android.EspressoLink_androidKt.runEspressoOnIdle(EspressoLink.android.kt:91) at androidx.compose.ui.test.junit4.RobolectricIdlingStrategy$runUntilIdle$1.invoke(RobolectricIdlingStrategy.android.kt:69) at androidx.compose.ui.test.junit4.RobolectricIdlingStrategy$runUntilIdle$1.invoke(RobolectricIdlingStrategy.android.kt:51) at androidx.compose.ui.test.junit4.AndroidSynchronization_androidKt.runOnUiThread(AndroidSynchronization.android.kt:33) at androidx.compose.ui.test.junit4.RobolectricIdlingStrategy.runUntilIdle(RobolectricIdlingStrategy.android.kt:51) at androidx.compose.ui.test.junit4.AndroidComposeTestRule.waitForIdle(AndroidComposeTestRule.android.kt:293) at androidx.compose.ui.test.junit4.AndroidComposeTestRule.waitForIdle(AndroidComposeTestRule.android.kt:286) at androidx.compose.ui.test.junit4.AndroidComposeTestRule.setContent(AndroidComposeTestRule.android.kt:281) (next line in stack trace is my test code.)
I am using:
- compose 1.0.0
- kotlin 1.5.10
- espresso 3.4.0
- robolectric 4.6.1
It did not matter whether I ran the test in AS or on command line.
