android - Run Jetpack compose tests with AndroidJunit4 and no device

Question

I'm new to android testing and no idea whether this can happen or not.
Is it possible to run Jetpack compose unit tests using androidx.test.ext AndroidJunit4 runner?

So we don't need to run instrumentation tests and use a device.

Here's what I've tried:

app/src/test/:

@RunWith(AndroidJUnit4::class)
class ExampleUnitTest {

    @get:Rule
    val activityScenarioRule = ActivityScenarioRule(MainActivity::class.java)

    @get:Rule
    val composeTestRule = createAndroidComposeRule<MainActivity>()
    // createComposeRule() if you don't need access to the activityTestRule

    @Test
    fun greeting_showsGreetingText() {
        // Start the app
        composeTestRule.setContent {
            analyzerTheme {
                // A surface container using the 'background' color from the theme
                Surface(color = MaterialTheme.colors.background) {
                    Greeting("Android")
                }
            }
        }
        composeTestRule.onNodeWithText("Hello Android!").assertIsDisplayed()
    }
}

Running the test I get the following error:

No tests found for given includes: [greeting_showsGreetingText]
