End to End tests fail in the more recent compose versions

[NunoPontes]

Hello Philipp,

I've really enjoyed this course, congrats.

I've been upgrading the dependencies on this project to test something, and when I upgrade:

Gradle to 7.2.1
Kotlin to 1.6.21
Compose to 1.2.0-beta03

When running the TrackerOverviewE2E tests I get the following error:

com.plcoding.calorytracker.MainActivity@24abf32 has already set content. If you have populated the Activity with a ComposeView, make sure to call setContent on that ComposeView instead of on the test rule; and make sure that that call to setContent {} is done after the ComposeTestRule has run at androidx.compose.ui.test.AndroidComposeUiTestEnvironment$AndroidComposeUiTestImpl.setContent(ComposeUiTest.android.kt:470) at androidx.compose.ui.test.junit4.AndroidComposeTestRule.setContent(AndroidComposeTestRule.android.kt:200) at com.plcoding.calorytracker.TrackerOverviewE2E.setUp(TrackerOverviewE2E.kt:101)

Hi @NunoPontes,

This is how it can be fixed. Please follow the following steps:

1. Change the composeRule to the following type. Please replace ... inside <...> by ComponentActivity
   @get:Rule
   val composeRule = createAndroidComposeRule<...>()

2. Add the following dependency to your app module build.gradle.kts:
   debugImplementation("androidx.compose.ui:ui-test-manifest:1.3.0-rc01")

Enjoy.

Actually that approach didn't work but this did the trick

basically composeRule.activity.setContent { }
instead of composeRule.setContent { }`
