Jetpack Compose UI test breaks at setup

I'm trying a fairly simple UI test on a Jetpack Compose app.

The SUT is a login screen with two fields for email and password and a link for password reset.

When reset link is hit, the password fields hides and the email field stays.

Here's the entire test class:

@HiltAndroidTest
class LoginScreenTests {
    @get:Rule(order = 0)
    val hiltRule = HiltAndroidRule(this)

    @get:Rule(order = 1)
    val composeRule = createAndroidComposeRule<MainActivity>()

    @Before
    fun setup() {
        hiltRule.inject()
        composeRule.setContent {
            MyTheme {
                LoginScreen()
            }
        }
    }

    @Test
    fun onStart_shouldDisplayEmailAndPass() {
        composeRule.onNodeWithTag("email").assertIsDisplayed()
        composeRule.onNodeWithTag("password").assertIsDisplayed()
    }

    @Test
    fun resetMode_shouldHidePass() {
        composeRule.onNodeWithTag("resetPassword").performClick()

        composeRule.onNodeWithTag("email").assertIsDisplayed()
        composeRule.onNodeWithTag("password").assertDoesNotExist()
    }
}

When I run them individually, both tests pass. When I run the class, the second one fails.

And as I noticed, it is not even in the test function that the failure occurs. It breaks in the setup function but I couldn't pinpoint the cause of the break. I can set breakpoints on hiltRule.inject and composeRule.setContent, the breakpoints do hit but the process gets killed even when stopped by the breakpoint.

And there's also a log for the failed test that says something about unregistering an input channel.

You need to add this line in your class

@RunWith(AndroidJUnit4::class)

and these lines are not necessary for the code

@HiltAndroidTest
@get:Rule(order = 0)
val hiltRule = HiltAndroidRule(this)
hiltRule.inject()

Your code should looks like

@RunWith(AndroidJUnit4::class)
class LoginScreenTests {
    
    @get:Rule
    val composeRule = createAndroidComposeRule<MainActivity>()

    @Before
    fun setup() {
        composeRule.setContent {
            MyTheme {
                LoginScreen()
            }
        }
    }

    @Test
    fun onStart_shouldDisplayEmailAndPass() {
        composeRule.onNodeWithTag("email").assertIsDisplayed()
        composeRule.onNodeWithTag("password").assertIsDisplayed()
    }

    @Test
    fun resetMode_shouldHidePass() {
        composeRule.onNodeWithTag("resetPassword").performClick()

        composeRule.onNodeWithTag("email").assertIsDisplayed()
        composeRule.onNodeWithTag("password").assertDoesNotExist()
    }
}
